Tried em all, raced on the Michelin and Dunlop. Love Metzler rains. Dunlop hands down for me. Quick warm up and very predictable. Awesome feedback. Michelin tend to have more outright grip, but when they let go, forget it. Michelin high sides i used to call em.

Each of these podcasts with Kevin Cameron is a concentrated college-level introductory course on the subject, with the exception that Mr. Cameron is a real expert in the subject matter and can explain things in a thorough yet comprehensible manner. If I had had teachers like Kevin Cameron, I'd be a genius by now.

Reminds me of Burt Munro’s using shoe polish to fill the cracks in his tires (as shown in the World’s Fastest Indian and maybe not true to fact!)

The D364's had that serious pointy tire in the center and wide "sides". I loved the "fall in" when coming off the point to the edges. Not as lot of fun when riding on SoCal grooved freeways, lots of fun in the canyons!

Always avoided Bridgestones in the past because I don't like the way they feel flat when cold. Bought an XR1200 last year, disappointed because it came with Bridgestones BT023Fs. However, they have been great, warm up quickly, plenty of grip and feedback, haven't enjoyed corners so much in years. Shows the improvements over time.

Pirelli MP7 saved my life. 17" came stock on the 89 FZR1000 and everyone hated them as being "TOO AGGRESSIVE." The shape was almost pointed with flat sides at 45 degrees not like the rounded shape even found on slicks today. How that tire design saved my life. I hit a raccoon at the beginning of the apex on a long 100 mph right hander approaching North Street on the Merritt Pky south bound. The impact of hitting the large animal at high speed launched the bike a foot in the air and it landed a half lane over still laid over on a 45 angle at 100 mph, no stand up, no tank slapper. What did happen is the impact had me screaming like my wrists were broken, I couldn't move my hands and the whoopdies were bad at that speed. The tires tracked straight, I was able to slow and downshift with no clutch. Many riders have been dismembered by the I-beam posts of the Armco guardrail. Tires have an optimal tempeture. Car, truck, trailer, tourer or racing motorcycle. Tire flex creates heat that why a trailer tire going flat on the highway blows out the sidewall. An under inflated touring tire on an overloaded bike at 100 mph separates at the nylon cords. The inner part stays inflated while the outer part rips the bike apart until it breaks and gets spat out at Kenly, NC. I'll get off a fast run and touch my tires, truckers do the same touching wheel bearings to. You can add heat by lowering your tire pressure and allowing more flex on a cold day, and the reverse on a hot day at high speed maintain optiminal tire pressure/ tempeture. Here's a good cold tire story. I took a right out of my driveway and put my 98 R1 on one wheel. There's a slight left so just lean a little and ride the curve on the back wheel. It will steer on one wheel if you're not too high with the wheelie. I took it too high and the bike started to fall over to the left, not steering. I closed the throttle on the cold tire and it reverse skidded as I was crashing. I feathered in some throttle and just as the tire hooked up I didn't want to highside so I went to full throttle and spun the tire. The bike whipped back and forth a few times and straightened out. I rode around the block and put it away. The tire was scraped to the edge in the wrong direction like you'd get in a reverse skid from the tie not spinning fast enough.

In the late 80's I had a 750 Ninja GPX (not a ZX7). A buddy of mine used to race one at Willow. He bought a 1987 FZR1000 and started racing that. I took off all of the "go fast" parts from his 750 and put them on mine. He had a set of Marvic rims on his 750 that he was going to use on the FZR, but the front rim didn't fit the FZR. I bought a front Marvic rim for the FZR, we traded front rims and I bought a rear rim for the Ninja. The rim size was 5.5x17 for the rear and 3.5x17 for the front. He had been running Dunlop slicks. At the time there were no "readily avalible" 180x5.5x17 rear street tires for the rim, so I was stuck running a slick on the street for the rear (no fun). I was at the local aftermarket bike parts store (remember them) in Oxnard when the tire guy came in with a new set of Metzler ME33 street tires in the sizes I needed. My buddy bought them with his racers discount and I bought them from him. Mounted them up and for 3 months I was running around with the only 5.5 street tire around. Lots of weird looks and double takes from people at The Rock Store and Nukem's seeing a bike that came with 16/18 rims running 17's with that "wide" rear tire. LOL! They were OK, much better than a slick on the street. When Dunlop came out with the D364's they were the cats meow! I ditched the Metzlers for a set of new D364's and never went back. When Dennis Smith used to run the Dunlop tire truck at the races at Willow he would have a serious amount of D364 take-offs he was selling from the "used tire rack". LOL! We used to buy a bunch of "used" tires from him. Never had an issue with them, you just didn't buy the totally rashed out tires. Dunlop was the tire I used after that. I got out of riding street bikes for years, when I jumped back in I was living in the PNW. That's when I was introduced to the Michelin Pilot Rode tires. Love them in the PNW! Still use Dunlops on the KTM 300 for the PNW singletrack gnar, first the D756 EX and now the AT81 EX!

The first dedicated motorcycle slick was developed by the English Avon company in 1960. Kenny Roberts used slicks from Goodyear when he started riding GP 500 for Yamaha in 1978.

I run tires whìch mimic the beloved dùnlop k81..tìre. This is the shoulder that features..gaps of non conti uous tread....this acknowledges the need for high communication and controlled drift to finish corner properly... Sport tires today feature unbroken high traction cornering surface. This means tire will hang on tenaçiously as loads get higher....when the load maxes and tire lets go tends to snap ..releasing all the force at once! More useful is a tire with less total grip.. but high communication..anď a broad band of disengagement! I raced 20 years..best tire i ever had was a worn beyond use racing wet from our race team....it was incrediable! It was never "hooked up"...never ",unhooked"! Made throttle like a rehostat for pointing the bike!! Great casual fun ..using as a steering tool on my yam tdm 850 sport bike killer! 12:52

I noticed a "change" as soon as we went to radial tyres. It was night and day for me. As of 2000 literally any road tyre could be regarded as "almost" race rubber tyres of old.

I’ve had great experiences with Michelin sport tires and Bridgestone cruiser/touring. Decent with Dunlop American Elite, ME888. Bad experiences with Avon Cobra Chrome, with two fronts cupping really bad and rear flattening off in under 8k miles.

All the talk now adays seems to be about chrome, bling and the last bolt on part you got from your dealer. back in the day we debated topics such as ' by putting naphthalene rich moth balls in your air box does your motor benefit from a bigger fuel charge', discuss.

I would love to hear your thoughts on the "dark side". I don't ride a bike that I would ever do this to. ZX14. But I am one of those rare ones that is a member of the Victory riders group, which some have been going this way. My thoughts are on big cruisers these people can drive straight really well and that is about it.

Gents, my question is about setting tire pressures for street riding. For the purpose of my query let's use the owners manual figures of 36 front / 42 rear. Scenario: the bike is inside the garage overnight, where the ambient temp is 55 degF. The bulk of today's riding will be in 100 degF temps. Shall I set the 36/42 in the cool of the garage, without regard for the hotter temps that will be encountered during the ride? What would the protocol be if the situation is reversed? The bike is stored inside a very hot shed (95 degF) and the riding will be along the chilly Hwy 1 (60 degF). Again, shall I set 36/42 in that hot garage?

@donaldhipple4921 9 ай бұрын

In my experience tires still are not offering great traction below 45°. They certainly much improved in every other aspect. In my early experience there was K81s then K491 then ME33 & 99. Now in the radial era I find Dunlop, Michelin & Metzler all have fine sport/touring choices, but Dunlop tires can be difficult to mount.

Didn't Michelin stop their 3CM automated manufacturing after the Power 2CT recall? I think their radial tyres are still hand made in Spain (and Thailand, sorry I forgot)

I have ridden dirt bikes on pavement with full moto knobby tires for the last 60 years with no surprises ...sure they side with half the traction of street tires ...but when knobbies let go is very gental with a big huge window of drift before catastrophe...giving you plenty of time of feed back to counter react to make the right decision of recovery ... And when this repeats itself and you have adjusted your skills to react with the same types of slides and skids and tire bounce... That's when the game becomes fun as you will catch yourself deliberately going out of control only to throw a big slide playing like your Jay Springsteen on the mile... But only at traffic speeds of 30 to 50 mph on wet pavement ...dry pavement it's the same only at higher speeds to a 100 ... But it's a different story with DOT knobbies .. a completely dangerous situation you throw yourself in that you're not ready for... Dot nobbies are the same patterns as regular Nabis except for one dangerous point...p dot nobbies are much much harder compound.. imagine when he was a kid in first try to ride your bicycle on the rims on blacktop instead of having rubber tires at all. You couldn't even make it up to speed and if you tried and dead then you couldn't stop that describes dot knobbies.. totally unpredictable tires with false sense of security... As one second they're handling great and the next second you're being rushed to the hospital with a broken .

Why do some tyre (pairs) have a silica rich front, but none in the rear?

@JoshNewby84 7 ай бұрын

Because the front is responsible for pushing water out of the way, allowing the rear to grip dry pavement. Silica has a good coefficient of friction on wet tarmac, but loses some grip in the dry. This makes it better suited to the front tire.

@flexjay87 7 ай бұрын

I will concede tire technology may be better than the past, but street tires cost way too much, especially compared to car tires, when you consider how many miles you get out of a set of bike tires. Just middle of the road Bridgestone Sport Touring tires for my bike cost around $ 125.00 - $ 200.00 a piece. Now, that might be okay, if you could get 30,000 miles out of them. But when you consider cheap Car tires are the same price, but are often rated at 60,000 + miles. Also bike shops charge $ 50-100 dollars for mount & balance per tire , compared to $ 20 bucks per tire on cars/ trucks.
