Do faster bikes go round corners quicker due to fatter tyres? - SV650.org

No mickey taking please. On track for example, will an R1 be able to take the same corner as an R6 quicker due to the tyres having more surface area on the track?

I was always of the understanding that fatter tyres meant slower cornering. I thought that was why some R1 riders we know have changed the 190 rear for a 180...............to quicken up the steering.

What a ridiculous question....we all know R6 riders are far superior/faster than R1 riders

Wouldn't that be to get it to turn in quicker?

Yes, and therefore wouldn't it take the corner quicker, theoretically?

corner speed would not matter either size will corner at the same speed....

its the turning in that speeds up, the transition from side to side is quicker with thin tyres

I mean are they capable of it rather than do they and I don't mean corners so long that they do it on power.

I would have thought that the contact patch size of the tyre with the tarmac is the critical factor. This would be affected by tyre width, profile and the load on the tyre.

Wider tyre only means that a little more rider input would be needed to get the bike to lean in. Much of that though is negated by the "quick" steering geometry of many bikes.

A race setup BSB bike running a 200 section rear will turn as quickly as a BSB125 GP bike. BUT although the BSB bike will have more side grip than the 125..it will actually be the 125 in skinny tyres that will corner quicker.

Its all down to lots of things...too much to explain really.

Putting a bigger tyre on your bike is not worth it IMHO and can slow the steering slightly on the road. On track a 600 can run a 180 or 190..but you do have to set them up differently.
