Fitting and Testing 200/60 Profile Tyre on BMW S1000RR - Supercorsa SP V4
HTML-код
- Опубликовано: 18 сен 2024
- I’ve done a lot of miles on the road and on track, but have never ridden on a 60 profile tyre. So In this video we recorded an experiment where we fitted a 200/60 17 Pirelli Diablo Supercorsa SP V4 tyre to the rear of our BMW S1000RR, a 2015/2016 K46 model. The original tyre on the rear is a 200/55 17.
Without making any geometry changes to the bike, I expected it would make the steering feel a little too fast because of the change in rake and trail, but to my surprise the handling was better than it has ever been.
This video provides specific details about how much the rear axle is raised with the profile change, how it handles on a test ride, and what we did to the preload adjustments on this bike. After the ride I spoke with Joe Salter from Ride Dynamics on the Gold Coast to get an understanding as to why the bike actually handled better with the higher profile tyre.

Hey Mate,
Thank you so much for the video. It's surprising how similar our bikes are. Here are a few things to consider:
There's something called an eccentric washer on the shock absorber. Depending on who handled your bike during manufacturing, that washer is often in the "lower" setting. By flipping it, you get the same benefits as going to the taller profile, with one major advantage I'll discuss below.
You didn't mention Traction Control, which I think is an important topic. Our ECU lookup tables are generated by the ABS sensors, meaning they compute slip/speed based on assumptions about tire circumference. By increasing the tire size, the computer allows more slip before activating traction control. Here are two and a half solutions to this problem:
1 Ask your dealership to change your ECU parameters. I went from a 190 to a 200 tire. You likely didn't need to do this because your forged wheels probably come stock for a 200/55 profile. BMW reprogrammed my ECU for the new rear tire size at no charge.
2 The RCK3 (BMW Race ECU software) has a table for tire size for this exact reason. It's not worth it unless you're using other RCK3 features.
3 In User/Slick modes (or all modes if you have your ECU flashed), you can adjust your traction control with 15 steps, giving you a few % more/less slip in absolute terms.
In the real world, tire sizes don't always match their labels. My Pirelli 200 tire is actually around 195 millimeters. This manufacturing "wiggle room" is why people have different opinions on this topic. Some 200 tires are actually 205, others are 195 (and everything in-between) , which affects traction control behavior. BMW allows us to adjust slip manually to account for these variations but you can go only so far before you're up against the wall of -/+7 DTC
P.S. Ask Joe where he thinks the DDC suspension belongs. It might be time for Mupo, my friend
Cheers
Awesome information mate, really appreciate the technical aspects of this. Interesting how sizes don't always match labels. Thanks for the education
Nice video.
I have just done the exact same experiment with my 2019 Tuono V4, except I am running the Corsa 4 instead of the Supercorsa. I have used 190/55, 200/55 and currently the 200/60.
Like you I expected the 200/60 to quicken the steering as it is significantly taller than the 55. However, just like yourself, I found no noticeable difference in turn in compared to the 200/55. The biggest difference was how the bike felt on the side of the tire. It is so stable and confidence inspiring in high speed high angle turns - especially when under acceleration.
Interestingly the 190/55 is the quickest steering tire, which is kind of counterintuitive from a geometry perspective. However, after much chin scratching and dug into the tire specs and discovered that there is a significant difference in weight between all 3 sizes - with the 200/60 being much heavier than the 190/55. All I can assume is the the rotating mass plays a much greater role than geometry in quick side to side transitions.
For me I think I will go back to a 190/55 for general road/canyon use and roll out the 200/60 for the track.
So many variables ay, it's an interesting puzzle. Thanks for the details of what you did mate, appreciate it
Tip for fork geometry, check how much front tyre edge is not being used ,if it is excessive over 5mm you could lower the front end if there is no strip using whole edge front tyre you could raise the front end ,tyre can only be read on fast riders bikes that have been cranking corners and hard braking also. A very fast rider taught me this trick ,bike higher in front end great for late braking but may sacrifice mid corner grip 👍sik bike also
thanks for the tip mate, appreciate it as I am sure other readers will
Thanks for this. Never even considered it. Ill give it a go
@@TheBikeStig very fast rider told me this trick ,only go 2mm at at time based on what you think your bikes doing he also said you don't want to be over the edge no where to lean from there ,I'm going lower front end K8 this week 2mm reckon it will give me better mid corner grip 👍
@TheBikeStig also raising rear of bike have same effect on front tyre something your prob aware of to, good to have a wear indicator for assessment on bikes handling.
@@99gpandy28 keen to hear how it goes mate, I am definitely going to drop that last bit at the front of this bike so I have some data on what it does
I’ve had the pirelli supercorsa V3’s (200/60/17) on my 2017 Suzuki gsxr1000 and I love them.
Love the turn in and edge grip.
I didn’t need to adjust the front forks.
The guys at the bike shop were telling me it won’t be good etc.
I’m glad I didn’t listen. I love the balance of the bike now.
I guess everyone is different on what they prefer though.
It makes the bike longer geared so taking off from a standstill is less aggressive but when it gets going it is even faster than before.
I may change the sprockets up for a better balance.
The 200/60/17 is the same size as a racing slick I think.
I really like these pirelli’s, so much confidence.
The V4’s will be even better.
🇦🇺✝️
its interesting that the expectation is a negative affect on steering but then it turns out to be better, I have the lower gearing mine as well which works a treat.
Thank you for making this video, I'm considering a 200/60 for my RR as well.
its definitely worked for me, Im not going back to the 55 now 🙂
@@TheBikeStig Many thanks. My choice is made, 200/60 it is!
Love your work Jorge 👍
cheers mate
Fantastic info, thanks mate 👍
Thanks for watching mate
cheers mate
This can help that speedometer discrepancy which every bike I've had has.
no mate won't change it, I am fairly confident the speedo is read from the abs ring on the front end of the bike so re gearing and changing profile won't change speedo reading
@TheBikeStig oh snap that sounds right. I was hoping the vehicle speed was calculated inside gearbox somewhere.
@@rtownsend744brad im glad its not lol
I had the thought if you had a steering stabilizer, then that could have dampened the twitchiness of the steering more back to what you normally use or lessen the feel of turn in collapse feel.
Not sure if what I was saying came across properly, there was no twitchiness with the new set up at all, the cause of the feeling of the front wanting to tuck was because of an imbalance between front and rear, we actually fixed that feeling with preload changes. The 60 profile tyre, now in combination with new suspension is spot on. Chers mate
Great video thank you. So what pressure front and back do you usually use on road? 26 on back you mentioned?
I only ride this bike on track or on spirited range rides, have been running 30psi cold front and 26psi cold rear on these Pirellis, I know we all seem to prefer a bit more in the front for track and hard riding.
@@TheBikeStig thank you much for your answer! Appreciate it.
I live in Hong-Kong on hot weather and usually run 30 front 29 back for spirited rides on my 1299 so glad to have your expert feedback
I have the 200/60 on my zx12r. I love the way it handles it is great at low and high speeds and sticks to the road like a fat kid on a cupcake .
Thats awesome, the more I hear about these the more I am convinced of their benefits. Cheers mate
Love the video! I have a question, I've one diablo superbike 190/60 17 (rear). Thinking about going into a track day, do you think that's ok to use this tyre, or should I go for one 200/55 instead? Thanks in advance!
it's a great tyre, personally I wouldn't worry about any size changes unless you are looking for a specific outcome such as more edge grip or geometry changes etc. We run standard 190/55 on our coach bikes at the Superbike school.
@@TheBikeStig Thank you!
I'm using a 200/55 right now, and I just can't get the quick back to back turns in the mountains. I'm thinking of going down to the 190. But then again, I'm no Marquez so it probably won't matter! 😁
haha, might be worth trying the 200/60
What did you think to the supercorsa sp v4? I’m torn between these and the metzler td slick for track
depends on how you ride mate, I am more inclined to use Racetec RRs or Supercorsas for track days, but that's because I prefer the front end stability they provide when braking super hard into corners, the TD feels less stable to me. However, if you aren't out there smashing out super fast times on a 1000 bike, the Metzeler TD slicks are fantastic.
My question would be does a larger tyre affect the tc or dtc? I've an 18 model which uses a 190 55 and having issues getting that size in slicks but i can get a 195 65. Make much difference to the electronics you think?
I have asked around about this, nobody seems to have had any issues, I know I haven't had issues. Would it change things slightly, of course as it is a slightly different tyre profile and when upright will be higher, but when upright DTC isn't engaging. When you get onto the edge it makes sense to me that it is the same as other tyres when it comes to tyre dimensions, it just has a better surface profile for grip. Not an issue for me
@TheBikeStig cheers, seems I need to suck it and see.
@@solo_dingo personally I'd give it a go, just measure the ground to centre of the axle for both so you understand the actual height difference. I wouldn't expect any issues to be honest.
I have a 05 gsxr1000 and by mistake i got a 200 55 17 usually i used 190 looking just to make sure im good with tht supercorsa v3 200 55 17 iguess i should be find i dont push the bike in curves so i should be fine
You will probably be fine with this, I spoke to people from Metzeler and Pirelli and they indicated that there is a range of rim widths that accommodate the various tyre sizes. We've run 200s on 190 rims on the Beemers and do not have an issue.
any updates on this ??
Nothing other than it's my preferred tyre now. set up is great
I tried this tire on my Tuono… Better turn in and hold a line better it seems but sucks at high speeds in a straight line
I have re-geared this bike, it's down 1 tooth at the front and up 1 tooth at the rear, works a treat
Will affect the ABS and traction control ?
a different rear size would affect traction control I believe as it works on rotational speed difference and this changes the relationship between front and back. What we dont talk about is how much does this affect that measure when the tyre is at lean ... my stupid brain says there's an 8mm higher radius when the bike is vertical, but traction control comes into play at lean. I might measure what the difference is at lean one day, I feel it might be less than people think.
OK for the track but less high speed stability for the road.
I probably ride too slow on the road to notice it mate lol
