Royal Enfield Classic 350 16t sprocket upgrade really worth doing? Here is an honest 2000Km opinion

[@dasp125]

I have got the full Hitchcock exhaust system, dna air filter, FuelX pro (set to 2) and a 16 tooth front sprocket. GPS recorded 78 mph top speed. I talked to my local Enfield mechanic and he said the classic 350 is restricted to 80% of its max revs via ECU. Adding a 16 tooth sprocket lowered the revs, meaning you can go faster before the engine reaches the 80% rev range. This also means that you can ride full throttle in 5th gear all day and it won’t harm the bike. Hope this helps.

[@Coastriderscotland]

Hi Mike, good info there from yourself and previous post above regarding the top speed options 👍 A lot to try I hope first someone else gives it a go and posts there results 😁 Thanks for posting this handy info! 😁👍 Cheers Bruce

[@Ernes446]

Loaded camping trip, 1600 miles to Colorado with 16t and DNA filter was a bad experience. I’m 6’ 210lbs, and the bike would max around 55-60mph. Often I had to down shift, canceling out fuel savings. I’ve put the 15t back and easily get to 72mph and keep it there on fifth. I agree you could do a higher top speed with 16t, but I would almost never get there. Ready to do another hiking trip to the mountains with a 15t! Now just need to fix the speedometer

[@vaibhavverma2960]

With everything stock one can't ride the motorcycle at 5th gear on top speed. Would it harm the engine.

[@philthompson2581]

Hello I think if you block every other aperture in the abs disc. You would fool the restrictions. But you would loose your abs.

[@Coastriderscotland]

Be interesting to see it done, hopefully by someone else first 😁👍👍

As a mechanic looking at one of these for here in the US, most of the local roads are 55 an under. But the ability to do 70 is just surviving the the big road in to the city. Its usable but you really need to be able to hit 75 or 80 every now an then. So I put a little though in to how the speed limiter works. But you can only do so much without owning one to actually test on. And there are no local dealers to even look at one. So its all theory. Assuming what people are saying is true that its speed limited using the ABS sensors, thats easy to minipulate. I would not do this other than to test, but someone could unhook the ABS sensors. Your ABS will not work, nor your speedometer, but neither will the limiter. Put a GPS on the bike an see what it will do. Preferabilly somewhre you are not going to need the ABS. You could also unhook one then the other to see if the limiter is using both or just one. The bike will probably turn the ABS light on doing it though. You have some other options for a more long term fix. The easiest is bigger tires. As I understand it from other videos, the speedometer is off by about 5%. Adding 5% bigger tires (outside diameter) that would be fixed an you would be going 5% faster, (what the speedometer actually says.) Two issues though. Will bigger tires fit? An can you get bigger tires? The rear you can but it is running the biggest front tire you can generally find already. To find a bigger tire for the front, you need to buy a classic tire in a no longer common size, an measured in inches. Probably from someone like Coker clasic tire company. My math says something around a 4-19. Would a tire 4 inches wide an 4 inches off the rim fit? This also raises the gear ratio on the bike which you may or may not want. Right about the same change as the 16 tooth gave you. If we knew which ABS sensor is used, changing only one tire is an option. Another option is to change the ABS rings. The ABS counts the holes in the ring as they go by. A ring with 5% fewer holes would do the same thing as getting bigger tires, without changing the gear ratio an buying specal tires. An you could take this a bit firther if you didnt care about the speedomiter being accurate. 20% fewer holes would give you 20% more speed before any speed limiter would kick in. And you could probably get away with that without the ABS acting up. But the ABS will probably fail to work correctly if you take this to extremes. Half as many holes would probably not work well with the ABS. The issue here is the rings. On mosts bikes they are a bolt on piece that is easy to reproduce. The photos I have seen of this one makes it look like the ABS ring is part of the brake disk. Thats a bit harder to reproduce. You can make a ABS ring with whatever holes you want with basic shop tools. Building a brake disk takes some specialty equipment. Again, this is all based on theory of how it should work. I do not have one to test myself.

[@Coastriderscotland]

That’s got to get folks thinking about that top speed what you posted! I’m sure someone will give this a go! Thanks so much for sharing your thoughts! 😁 Cheers Bruce

[@sissonsk]

I plan on traveling 360 miles on back roads in Texas Hill country each weekend that the weather allows. I'm looking for better efficiency and lower revs but I don't plan on going over 65 mph. So going faster isn't what I'm looking for but I'd like my RE Classic 350 to work less doing 65 mph. Adding a tooth to the front sprocket seems to be what I need to do.

[@Coastriderscotland]

Hi, the 16t does give a more relaxed ride with the revs a bit lower 😁👍

[@B0M0A0K]

Two questions for you, unfortunately, not related to the sprocket? Are you still running with the knobbly tyres (the bike seems planted in that mud and grit) and you mentioned in a previous video that you removed the wrap from the exhaust, why was that please? Another great video, clear and to the point. Well done again!

[@Coastriderscotland]

Still on the K60 trail tyres!, I ripped the exhaust wrap underneath when I got the bike stuck in that ditch and it started to unravel, I don’t know if all exhaust wrap is the same but that stuff was real itchy with the fiberglass type material, Cheers Bruce

[@tonylawton6513]

If you want more speed out of the 350 you can change ABS ring on the wheels to one that has an extra hole or two, this is how they restrict it.

[@Coastriderscotland]

Hi Tony I have heard this mentioned already and like to find out where to get them etc 😁🧐 Cheers Bruce

[@tonylawton6513]

@@Coastriderscotland personally i wouldn't want to go fast on this bike its a plodder a bike to chill out on, if your serious about wanting more speed the only correct way is to change the cam, on the 350 J engine its a very easy process, get rid of the cat do the filter and you will be zooming around in no time, or just buy a triumph speed twin 1200. 🙂

[@tanmaysinghal1999]

Hi tony can you tell more about how abs holes and speed restriction work

[@robertadams4415]

Thanks for the info mate

[@Coastriderscotland]

Thanks Robert, glad you find some info of use 😁👍 cheers Bruce

[@justatanu]

Does it effect speedometer?

[@Coastriderscotland]

Hi, Speedometer is not effected by the change to gearing, top speed limiter is also unchanged and remains 73 mph or there abouts

[@Woody_61]

Just curious mate. I have an ad blocker in my browser so I watch all you videos without ads. Does this affect you moneterisation?

[@Coastriderscotland]

Hi Craig, I don’t know but don’t worry about it 😁👍cheers Bruce

[@RockDinosaur695]

My meteor feels a little buzzy and feels like it wants to go into a 6th gear when it gets around 55, what do you think would be the best mod or mods, cheers

[@Coastriderscotland]

Adding a 16t gearbox sprocket would be the cheapest way to drop the revs

[@RockDinosaur695]

Cheers

[@ianhughesroyalenfield]

Morning Bruce, what is it like on slow, very steep inclines, does it bog down ? Cheers

[@Coastriderscotland]

Hi Ian, you have to be in the right gear definitely for slow steep climbs, you will see this in the next film on 2 real steep roads that had WW2 ambush road blocks on them, I’m down to second gear. On big hills into the wind you will have to drop to 4th to maintain 60+ Cheers Bruce

Strangely enough, I have one of these sprockets in my garage, and I’ve done all the other mods, filter, air intake and Hitchcocks stainless exhaust for my Meteor. My other bike is a Bullet 500… love your videos as I can enjoy them when it’s too cold for me to go out on my bikes. (I have emphysema, and don’t breathe too well under 10 centigrade….

[@Karan-iy5mz]

My classic 350 2015 already had 16 front sprocket . Are newer ones coming with 15?

[@Coastriderscotland]

Hi Karan, your 35o if 2015 will be the older generation 350? (Bullet) this is the 2022 onwards J engine Classic 350 with same engine as the Meteor and Hunter 😁👍 Cheers Bruce

[@Karan-iy5mz]

@@Coastriderscotland i did some research online and found that royal Enfield classics before the new one had 16t. Classics production started at around 2011-12 i think. Before that there were only bullets and electras.

Good over view of this mod. Just got a red and Chrome. Pulled off the rear seat and pegs Imho looks way better. Tried removing the air filter cover done the remap tick over. Huge difference,so got the DNA kit arriving this week. Next Hitchcocks cat replacement pipe as I like the silencer as is. May well give the sprocket a whirl . Tried the heel toe shifter dont like it so sell that and use the dosh for a sprocket. Cheers for the post Lee

Hi Lee, it’s a great wee bike that lends itself well to easy to do yourself mods with improving results! 😁👍

Nice one. :) Watching your last sequence there, was in E Linton today at nice wee Cafe, Votadini :) NOT on bike though, as I wimped out with the snow that had fallen. Also was going into Dunnie to have a wee look at the zero waste place :),

[@Coastriderscotland]

I crapped myself driving a loaned auto rear wheel drive to work yest morning! It would have prob been safer and made a hell of a good film on the bike! 😜 I pop into zero waste often, good stuff often pops up there but stuff goes quick so it’s kind of luck being there at the right time 😁 Cheers Bruce

[@richardcrighton8079]

did you do it? if so, what was the effect?

[@ejakeway]

@@richardcrighton8079 no not yet and after more high speed riding I don’t plan to anymore. I was still in my break in period so I didn’t go fast until after posting. I came from a Suzuki 250cc and the classic 350 accelerates much slower then that bike. Slow enough I’m not gonna hinder it any further by changing the front sprocket.

[@TheBggillies]

I've got a sidecar rigged to my RE Classic 350. I'd like to go the other way on the sprocket to get better acceleration. Any recommendations? Also, love the handlebars. Did you paint those yourself?

[@Coastriderscotland]

Hi, I’m sure Hitchcocks UK will sell a 14t lower than stock gbox sprocket, i know they-do a larger rear sprocket 👍

[@TheBggillies]

Thanks. I will check it out.

Hi Stuart. I have a clasic 350 fitted with a sidecar, would fitting the 16 tooth sprocket help the bike for a little bit of touring. ?

90 mph were reached by a Brasilian rider after an ECU flashing which has removed the speed limit 😉

@@Coastriderscotland It likely would be costly. I mentioned it only to make a point that perhaps a smaller rear sprocket would be more effective 😎

[@timsatchell6713]

Does the sprocket swap effect speedo readings. Thanks for posting.

[@Coastriderscotland]

Hi Tim, the speedo is controlled I believe through the ECU and ABS rings on the wheels. Which is also how the top speed is restricted to approx 73mph, with the higher gearing the bike pulls higher speeds in each gear and is less buzzy cruising along at 50 mph 😁👍 cheers Bruce

[@elwood62]

I purchased a 16T last year, but for various reasons never got to put it in. I think you give good reasons for doing it or not. I have an air filter and fuelx coming, my only hesitation is that I currently have a Meteor and have considered trading it for a classic. The parts are interchangeable so they would work if I did make the switch. Still winter here so I have some time to think about it.

[@Coastriderscotland]

Hi Elwood thanks for watching the film and your comment 👍 as you say you will be not riding as much or perhaps at a faster speed being winter so your sprocket can keep for summer or a new bike 👍😁 Cheers Bruce
