Contact Patch: Michelin Power Cup 2 Tire Test Intro

INTRO: full video here davemosstuning.com/contact-pa...
Mr. Moss decided to test Michelin's new Power Cup 2 race DOT tires. While it is a track oriented tire, in the United States that "DOT" label (Department Of Transportation) means these bad boys are technically street legal.

Dave, tks u so much for this & all the others videos you do. tks! tks! tks! your work bring so much to those who try to be better riders and could remind to most of riders that a motorbike is neither a simple transport mode, nor a "way of life", nor a funny/risky game, nor i don't know what else.. It's Motorbike and that's imply a certain consiousness of such a lot of things, like when you're a sailor or a plane pilot. you can agree or desagree, but as soon your wheels turn here on earth, you're dealing with a lot's of complexe and interactive phenomène. tks for helping us to get a better conscience and betterknowledge of motorbike, in thisgreat pedagogical simplicity that's yours! tks!

[@JamesTPzRoC]

Dave Moss Tuning You got it, man. Very informative video! I do have a question tho, Im still using Power RS for track now, and I think I will mostly like to get the Power GP to replace it later this year (Cup 2 is too sticky for my stock suspension). What tire pressure will you recommend for the RS and GP?

[@JamesTPzRoC]

@@CatalystReactionSBW Saw your tire pressue video, I got it now!

[@PAD32]

For those interested, here is my little contribution. I just went from Power RS to Power Cup 2. While the first one is great on the road, the feeling difference is huge on track. The rear never slipped while applying lots of throttle, even while cornering. It felt like I was far from the limits. Also the front feels a lot more stable under heavy breaking. That's very subjective, but that's what I felt. After 2 track days, the front is like new, and the rear is just starting to wear a little, it can do a lot more (intermediate group). I was worried about the wear after reading people talking about track tyres, but it can last several track days with no issue, at least at my level. I also had a slightly wet track the first day, it was raining a little. Even if I was riding relatively slow, the tires gave me confidence. I tried to find the limits by applying full throttle on straights, but no way, it has tons of grip, even on the wet with 165 HP... I'm totally happy with it so far. Just one consideration. 190/50 is not available, so I had to put a 190/55, it didn't fit and I had to modify the mudguard XD.

[@CatalystReactionSBW]

Thank you for sharing your experiences for others and paying it forward for others to benefit from!

[@jimcarroll2557]

Thanks for your contribution. I'm more confident making the same switch as you going from the RS to the Cup 2. Great video with clear temps and pressures. I'm looking forward to my next track days with this tire. Cheers!

The front really really holds , I had it leaned over this weekend and I thought for sure it would go . I was racing with buddies at a trackday and came in way faster than normal and hit a bumpy patch tire never even slid a bit. I’ve done same thing on same corner with the rs11 and they skipped and slipped . Same bike same suspension these are good tires. Rear is picky and needs a good setup it will tell you if your off.

[@AdryDoic]

im on the end with my RS11 on yamaha R1 and think about to try these Cup2 ! what about durability? because my RS11 have super Grip but with some street use they flat spot in middle very fast. thanks Man

[@DylanGSXR]

Rs11 are not great on track imo , had a massive off in Spain from the front Letting go. The bad thing about this situation was I had power cups waiting to go on but thought I'd get one more day from rs11 , as my pace increased rs11 could not cut it . So as I stud at the side of the track looking at my brand new gsx-r with only 400 miles on it plus a broken hand I didn't feel to good and keep thinking why didn't I put the cups on ..

nice use of a contour gauge!

[@justaguy4real]

1:11 seeing the rotor there, do all bikes make a sort of grinding rubbing sound when free rolling, or are my calipers too tight?

[@KR4Z3D666]

All brakes will make a slight scuffing noise when free spinning as the pad is always in light contact with the rotor due to the design of the caliper piston seal :) If that scuffing noise is excessive or it doesn't spin freely then you can have slightly stuck on pistons, warped rotors, misaligned fork legs etc Hope this helped :)

[@KeyserSoze5421]

Recommended front pressures cold for track from Michelin are 30.5 and not 32.

[@justaguy4real]

0:17 seeing the tire bounce like that, wonder if there's a way to see how big patch is on my bike with my weight and psi, and how much it morphs like shown there, and if there's a way to determine what would be too small of a patch aside from low siding haha. I really need more education and experience for gaining more faith in tires and curves in general. Ive seen regular cruiser bikes handle turns and curves just like the sport bikes in front of them without problem, and even seen a couple cruisers with sport tires. 1:22 Interesting seeing the compound difference down the middle there.

[@applebitefool]

Great video. It’s pronounced Me-Che-LIN with an emphasis on the final syllable.

[@CatalystReactionSBW]

Merci!

[@TheLiddleBigChannel]

Does the carcass affect the fact that the front was still riding high after the initial geometry change?

[@CatalystReactionSBW]

Soft rear carcass = more deflection so that leaves the fork "higher" and therefore the bike requires more energy to steer.

[@jmannUSMC]

I think you can still use that profile tool for the rear tire, just use it to trace from the middle to one side, as the tire is symetrical.

[@CatalystReactionSBW]

Agreed! Dave wants to wait for the full size one......

[@jmannUSMC]

@@CatalystReactionSBW Us boys need our toys 😂

[@raynic1173]

You will then need to make sure the tires are level/plumb and then make sure that the gauge is level. Being that you cannot balance the gap difference for proper alignment and comparison. The gauge has to be square to the tires radial centerline. Or use straight edges and a square for any kind of accuracy.

[@Fee.1]

Off topic question for you, would you say in your experience bikes are steadily lighter, unlike cars which have done the opposite, or were there bikes lighter than today’s just 20 years ago even ? In any given segment although I’m focusing on low cc sport bikes and general consumer stuff not exotic materials like carbon fiber and high end

[@CatalystReactionSBW]

Bikes have been getting lighter since 2000, then it became a marketing point on how much lighter you were than the competition. That grew into composites and here we are now where bikes are mostly the same weight. Now, the war is for features!

[@GetHighspeed]

Is with the Supercorsa SP V3 more lean angle possible? The front tire from the Michelin looks "flat".

[@CatalystReactionSBW]

Both the PC2 and V3 are soft carcass tires. More lean angle requires firmer carcass.

[@RONIN-ff9sd]

Yo dave! How would you compare these to the Q4 sportmax? Or am i comparing apples to oranges...? I hope not. I'm looking for a really good track day tire before my next track day

[@braddavies137]

I run Q4s and haven’t had any issues. IMO I like them.

[@CatalystReactionSBW]

Carcass is completely different on the Q4's. Very soft so they are pressure sensitive. Not compared geometry yet but contacting Dunlop for a set to test.

[@ahmadyaqeenmohammad6564]

I'm confused why is the tire pressure on the rear is lower than the front.. Does it have to be like that just on the track? or can it be used on the street?

[@CatalystReactionSBW]

Pressures are set at Manufacturer's recommended, then I test from there based on carcass temps and feel. Fronts are normally higher from braking and cornering forces.

[@devinsmith3645]

On the Michelin power slick 2 what tire pressures would you recommend cold and hot?

[@CatalystReactionSBW]

Cold is what you choose based on where you are in the World and what road or track environment you are in. or you follow recommendations from Michelin to start. Hot is always 4-5psi more than cold.

[@czierwo]

I'm about to go for my third track day next weekend on my PowerRS's. I'm running intermediate upper mid pack with still very soft throttle application. On a hot day (30degC) ran 30f-28r psi cold. RS's felt like on rails. Will see how my third track day goes. Love RS's, but certainly for the next season, I may go Power Cup2. Not even sure if it's worth with my kind of speed lol!

[@CatalystReactionSBW]

Total gain cold to hot is 4-5psi, tested at the end of the 11am session (#3) and 3-4pm session in the afternoon so you can compare. We are slower in the mornings and faster up to a point in the afternoon. Quality over quantity regarding laps - don't stay out and embed mistakes as a standard behavior. Cost per lap should not be relevant.

[@czierwo]

@@CatalystReactionSBW next time I'll start on same tire psi as before, but not sure what hot psi should be for optimum performance. Will aim for no more than 35f and 33r psi hot... Tires developed some mice poo roll off, but not too thick or thin. Track is rather small (basically 2nd and 3rd gear) and abrasive with full on acceleration and braking. Pity I cannot attach pictures here 😏

[@CatalystReactionSBW]

@@czierwo Street - 3-4psi gain over cold is ideal. Check after 30-45 minutes of riding.

[@czierwo]

@@CatalystReactionSBW Problem is, we only get 15 minute stints per rotation. Up here north, in Canada. Not sure what my "hot" pressure target should be... Tires feel great anyways, and will stick to my current observation.

How/why or by what metric are you describing the tire in when you say “it’s drops off from 130 out”. Are you using a clock ? Or 360 degrees? If a clock (not sure how you describe that metric) how....like wheres 12 and wheres 6. Same question regardless of the metric I suppose

It is a clock face and 12 in top dead center of the tire

i know its an older video , but power gp vs power cup2 which has higer throttle to tarmac feel. i dunno if this is correct but im asking which is better in giving the feel that the bike just went warp speed ? not due to sheer acceleration but due to tire-tar feel or as i have now learnt, which track-road tire has the highest drive grip ? across the market Thanks

[@CatalystReactionSBW]

Power Cup 2 should start at 22 cold rear and 32 cold front for that event. Gain should be 4-6psi checked at after your 11am and 2pm sessions.

[@larsr.9310]

Hello, your video was just recommended to me. very interesting approach, although I find it a bit too theoretical. However, geometry etc. is not about the last second either. What I'm missing is a clear statement of where the tire stands in comparison to the Pirelli supercorsa road, where does the tire stand in comparison to the Bridgestone rs10/rs11. no criticism, just a suggestion. I'll be riding the cup² soon on a 2002 fazer 1000 street machine, rebuilt, with a different spring strut and fork and what Michelin recommends in Germany, you can use it without tire warmers. Many thanks for your approach and greetings from Germany ps: your test motorcycle is an R6 (?), can a 600 push these modern street legal racing tires to their limits at all, or is it more about the front brake?

[@CatalystReactionSBW]

Thank you for your constructive feedback Lars. Yes, the test motorcycle is a 2012 R6. A good rider with this motorcycle can certainly go beyond the limits with their skill level and/or the use of TC etc.

Slower turning is you decide where the bike goes via your inputs. Faster turn in is a match of bar energy and lean angle based on profile and fork position.

[@justaguy4real]

How easily, and what would the consequences be, for a rider to out ride or over perform a regular street tire like Michelin Pilot Roads as opposed to Pilot Powers and others? Could a sport bike rider actually low side or take a corner too fast and slide or lose control on Roads than Powers? I really had a lot of confidence on my Pilot Power 2's, and same or more nite on my Battlax S22. And couldn't a Pilot Road have as much traction with a lower psi (hence greater contact patch) as a Pilot Power ith higher? Just how much different can the rubber actually be between them all? Every new model comes out claiming better wet and dry traction. But of course they do otherwise what's the point? And I see riders riding ultra aggressive on tires of way older iterations without problems. 1:22 Interesting seeing the compound difference down the middle there.

[@CatalystReactionSBW]

I understand your thought process and the physics that you "see" as possible projections. You did not include carcass structure nor suspension set up and geometry. All tires will fail on grip at a given moment, hypersport tires having a higher grip/traction coefficient that single compound. All tires will fail earlier due to poor set up. Over riding would most commonly be low side as over 64% of all motorcycle single vehicle accidents worldwide are loss of control on corner entry.

[@kevincraig8257]

How come pressure are reversed on the track is it because of weight transfer

[@CatalystReactionSBW]

Braking stability requires less carcass flex and we do a lot of braking at the track. Hence therefore the higher pressure. Throttle inpts are generally smooth and metered so lower pressure and more grip = better control.

What’s the difference between 190/55 and 180/55 on the r6 rear?

[@CatalystReactionSBW]

aspect ratio (or height) of the tyre is represented as a percentage of the width of the tyre. In this example then, the height of the tyre is 55% of 180mm, which equates to 99mm. Do the same mathematics for the 190 so the 190 has more surface area to contact the ground.

[@richbonesjones4729]

@Dave Moss Tuning this was Michelins reply For more details, if wanted : The radial construction uses a ply running from bead to bead at 90 degrees to the direction of rotation and this is the basis of a radial tyre. This can be accompanied by reinforcing plies laid at much shallower angles, but a ply running at 0 degrees to the direction of rotation is always used. Michelins high performance radial tyres such as those that you enquired about all use a zero degree belt made of aramid. This offers greater strength for a lower weight than a steel belt, and it's also more flexible, allowing for a large and even contact patch and reducing wheel inertia and gyroscopic effects to give light and confident handling with easy changes of direction."

@@juicer404 Heat cycles are a thing of the past as tires have a lot of silica in them, so there is not much oil at all.

Hello, I'm writing from Germany :-) it might be difficult to describe... but my question is which tire is better... handling... grip...etc...pirelli spv3 or powercup 2. For the street Greetings :)

[@CatalystReactionSBW]

SP V3 and MPC2 are both soft carcass tyres. The MPC2 has no tread pattern on the sides therefore it will offer more rubber on the ground and a better contact with the road.

[@mauriiruam7146]

@@CatalystReactionSBW Many thanks for the quick response. :-) Agility? Change speed? Trust? Which one would be better?... I know that's a matter of taste...feeling...but you're the professional :-) thank you very much

[@CatalystReactionSBW]

@@mauriiruam7146 Stiffer carcass = more agility, so V3

[@mauriiruam7146]

@@CatalystReactionSBW thank you very much 😊 👍🤜🤛

[@miguellopez20111]

I thought that the 190 is the width ( horizontal) and the 60 is the height ( vertical ) , please correct me if I’m wrong , I know it’s an old video, I just subbed

[@CatalystReactionSBW]

Thanks for subscribing! Ratio between tire section height and nominal section width is correct!

What is their lifespan? I mean by riding only on twisty roads and race tracks.

[@CatalystReactionSBW]

I have 5 track days at A pace out of the set. No street miles.

[@DavourisRX8]

@@CatalystReactionSBW 5 track days at high pace is a lot. Thank you! 😊

Power 5 rear Diablo 4 front: a problem?

[@CatalystReactionSBW]

Tires are matched sets for roll profile. Different tires within a brand/family have similarities. Across brands would be less likely. Does it mean you cannot ride this combination? No - approach with diligence and see if the front or rear lead on turn in.

[@alangolightly9850]

Guess I'll stick with diablo 4 rear. Picked up a nail on rear. Afraid to repair.

[@CatalystReactionSBW]

@@alangolightly9850 There are very advanced items for tyre repairs now verses the car tyre plug. eg: Tire Repair Patch Plug 1/4" Auto Automotive Tubeless Tyre Repair Plug Patch 6mm Mushroom Nail Boot Kit Wired for Tire Repairs. I've used these many, many time with no issues at all. BUT, your mind has the last word......

Bought another Diablo 4.

HELP ME MR WIZARD!!! I need the extended life on the Pirelli Diablo Sueprcorsa SP's please! cuz 1700 miles doesn't work, they gettin spensive today.. help me please, I no can run the Michelin Highsiders, new bike spensive.. I needs grip them M's skeer me.. how to get more miles from the Diablo please

[@CatalystReactionSBW]

1. Set preload and damping. 2. Assess fork and shock travel used. 3. Optimize fork and shock travel. 4. Set cold pressures at 36 front and rear and ride. 5. Set cold pressures at 38 front and rear and test. Take notes on ambient temperature and the cold pressure you preferred. The hotter it gets, the higher the cold pressure must be.

[@MrCanonballs]

At 3:25 you are describing the cross section not the profile. The profile is merely the distance between the rim and the road... You may have heard the term "Low Profile Tyre". Another example is 190 50 17... the 50 describes the profile NOT THE SHAPE OF THE CROSS SECTION. ;-/ Having said that, it is only "nomenclature" and I don't dispute your great knowledge of how tyres work... but still it would be best if people are not confused by your malapropism.

[@JamesBrown-ux9ds]

Amateur vs. best in class professionals? Amateur rarely wins. May we say 'we knew before'? (Experiance, not guessing) If Michelin provides such a pair i try 'use as is' first - just because it's likely the quicker way to experiance. And we all know, you are you are just the same, but you wanted to show us spectators the basic principles and how to take action and responseability.

[@JamesBrown-ux9ds]

And I think Dunlop builds its motorcycle racing tyres according to this philosophy now for fourty plus years - at maximum average lean angle (now and then) they want to provide the customer 'with a side flat' - 'maximum rubber on the street'. And this typical maximum leanangle with predictably 'maximum rubber to the street' is for the rider easy to reproduce in every next corner, 'i know my lean angle, apply it' - a. quick for many, b. sales advantage (even if the driver does not reflect why) - 'i want me good Dunlop feeling again/back'. For some professional a reason to buy Michelin - 'i want it definitely best performance under each and all conditions, not 'reproduction of a feeling. Reproduction of a feeling 'is for amateurs'.'

[@Piridajac]

Why Michelin didn’t make 200/60 I want to try those tires on panigale but 200/55 it is not for that bike…???

[@CatalystReactionSBW]

Compare circumference side by side with other tires to see if they are the same diameter as a 200/60

[@raydolinger1980]

Uhhgg Uhhgg BASICALLY :)
