Yes interesting thought
Stock bikes with stock trim, I can wholeheartedly say that changing to a 55 profile will cause issues with blipper and quickshift to some degree
3 bikes 3 different tyres sizes, 3 different results. Good week
Those your groups bikes or the Bridgestone teams bikes in the picture?
For your group, what bikes and what tyre sizes and whats the feedback and verdict?
bike1 running 120/70/17 sc1 190/55/17 sc2
bike2 running 120/70/17 sc1 200/55/17 sc2
bike3 running 120/600/17 200/655/17 vo2’s
Was the 190/55 close enough to stock to have the bike work properly?
And the 200/55 & 200/655? They leave the electronics all confused?
Traction control work ok?
How about ABS controlled rear wheel lift mitigation? Did that kick in correctly or was the rear tyre all up in the air under suicide braking?
The only bike with no faults was the one on v02’s
The bike with 200/55/17 sc2 went into fault within 20 meters with a permanent line on gear indicator.
Needed a reset to clear, it then had shift issues and very intrusive tc
The bike with the 190/55/17 was fine until tyre wear seemed to cause shifter issues. Tc working fine.
What are the bikes? 2017/8/9? SP1's?
Thats odd that the bike on 200/655 tyre had no issues. What TC settings? I have 2 buddies here in the USA that when they run 200/655 the bikes never trigger Traction Control - ever. The bikes can carry the spinning tyre to stupid levels almost spitting them off many times. Switch to 190/50 and it intervenes as expected.
The 190/55 should have got closer to stock tyre height as it wore so not sure how it would be the cause of shifter issues while the overly tall 200/655 had no shifter issues.
Maybe Honda system is just fucked.
Strange ain’t it? All bikes 2018 sp1’s
It may of just been a one off on the 190/55 but not worth risking so blipper got turned off just in case.
We can only put it down to the change with the bigger front and rear on the v02’s maybe helping with wheel speed sensor?
Possibly. But to draw any meaningful conclusion we really need the 'as fitted' diameter and width of each tyre. As you can see the V02 may be dimensionally smaller than the Diablo, but that does not explain why the stock tyres work. These dimensions I have below are those published by the manufacturers themselves.
Then again the key may very well be wheel speed sensor ring diameter vs fitted tyre diameter. I will dig the rings out and do that maths later.
P1relli Diablo Supercorsa SP (SP1 Honda fittment 96.2% front/rear)
120/70ZR17 612mm x 134mm**
120/70ZR17 604mm x 121mm (Measured)
190/50ZR17 636mm x 208mm** (120/70 front is 96.2% of rear height)
190/50ZR17 628mm x 193mm (Measured - 120/70 front is 96.1% of rear height)
P1relli Diable Supercorsa Racing SC0/1/2
120/70ZR17 612mm x 133mm**
190/55ZR17 656mm x 203mm** (120/70 front is 93.2% of rear height)
200/55ZR17 668mm x 216mm** (120/70 front is 91.6% of rear height)
** this is a 'max width in service' dimension which I believe is the maximum stretched width Pirelli support vs the relaxed installed width on the correct width wheel.
Br1dgestone RS10 (SP1 Honda fitment 95.1% front/rear)
120/70ZR17 601mm x 121mm
190/50ZR17 632mm x 191mm (120/70 front is 95.1% of rear height)
190/55ZR17 650mm x 190mm (120/70 front is 92.5% of rear height)
200/55ZR17 655mm x 200mm (120/70 front is 91.7% of rear height)
120/70R17 604mm x 119mm
190/55R17 651mm x 187mm (120/70 front is 92.7% of rear height)
200/55R17 655mm x 196mm (120/70 front is 92.2% of rear height)
120/600R17 603mm x 117mm
200/655R17 655mm x 194mm (120/600 front is 92.1% of rear height)
You have saved me loads of time by posting this, cheers. I’m just trying to take it in and work out a plan. Keep it coming
So there is 1.5% difference from the 2 factory tyres
I am not sure. My P1relli (and I do the 1 instead of the i so the damn advert links dont get inserted) are not on the wheels any more and the resting diameter not installed is 605mm tall - yet the P1relli book shows 612mm.
We need proper 'as installed measurements' for proper comparison.
I can do that once the bikes are back from Spain, what I would like to do is find some other options for a track focused tyre that’s closer to the sp and Rs10
Just popped down to the local Honda shop and did took some measurements of the P1relli SC SP on a SP1 and SP2. Updated the post above.
The rear is probably not as accurate as I wanted - measured the tyres on the bike, measuring the wheels off the bike will of course be the most accurate.
The videos have started from the s22 test at Jerez, 44 teeth have just posted on Instagram
Keep a eye on them tyre sizes
So far all that sup is a picture of a helicopter ride to Jerez
Unless its not that 44teeth
They have done a walk by on all the bikes fitted with the s22’s
@44teeth on Instagram?
Ok I see the problem.
Different shit on the Instagram versus the Youtube vs the Facebook.
Pick a fuggen platform and run with it
