Hi Everyone, Need some advice on Rear Tyres please... Standard rear road tyres are 190x50x17 Fitted Dunlop GP Racer D212 190x55x17 (Electronics seem to work fine albeit size slightly different) Fitted Pirelli Diablo 200x60x17 (Electronics worked for 2 sessions and then seemed to suddenly realise that it couldn't cope with the tyre size - No ABS, No traction control and no quick-shifting Up or Down) Question is... is it likely to be the width of the tyre, the profile or a combination of both that the bike doesn't like? I'm concerned that reverting back to Dunlop's MAY not resolve the issue - Even though they worked fine last time - particularly if it's the profile size that is key. I don't have 100% faith in the electronics to be honest given the Pirelli's worked fine for a couple of sessions (perhaps until the electronics were called into action?) Thanks.
Hi and welcome. Unfortunately I can’t help with your question but I’m sure I’ve seen a post relating to it on here before. A quick search should uncover something. Failing that I’m sure another member with a better memory will be along soon
Ooohhh you've just re opened the can of worms that's had a lid on it all summer! Long and short of it is....... Don't change the tyre size and everything will work as it should do! Welcome to the forum anyhow!
I was thinking the same. If you go from a 190 50 to a 200 60 then the rear is spinning more slowly, so the electronics are gonna think that something is wrong.
Hi and welcome. Yes, extensively covered. See these: https://www.1000rr.co.uk/threads/2017-cbr1000rr-rear-tire-size-problem.34969/#post-499325 https://www.1000rr.co.uk/threads/2017-18-ecu-thread.37550/ Best advice is to revert to standard size.
Thanks All, So does no-one run the SP1 on Slicks - On the basis you cant get any 190x50's? When they did the original testing in Portamao, they spoke about the great V02 slicks! Quote: "Later on, we get a few sessions on the SP version – and the performance is noticeably cranked up. Much of that is from a cunning tyre swap – Honda has fitted Bridgestone V02 slicks, and they are a revelation in grip and sharpness, with no noticeable decline in stability." I'll get two sets (Probably the Dunlop 190x55 Slicks and a set for the road as spares) and see how we go in Portimao in November.
this is a sore subject with people wanting to change their tyre profile and honda electronics not paying along. The change from 190/50 to 200/60 must have made a difference in the OD to stop the elctronics working properly. On the plus side without ABS and electronic aids maybe you can enjoy the raw bike now
