Yamaha R6 rear tire size

What’s the current consensus for a rear tire R6 2017+ size- 180 or 190??

 

Street? Track? Tire Manufacture?

 

Track only usage. From what I gather, Michelin doesn’t make slicks in 180 anymore.

 

Here's a good thread to look at

Does a Pirelli Superbike Slick 180/60 fit on a 2017 R6? | 13x Forums

 

Wow! Thanks for the good information!

 

Hey guys sorry to add to this topic, but I have the same bike and thinking of running a 195 dunlop slick on the 2017 R6. Any geometry changes needed?

 

Changing from what tires... For what tracks... At what pace...

You'll likely need changes. But its a lot better/easier to fix issues found while riding the bike.

 

You’ll have to do some work if you really want to know… get out that yardstick and start measuring!

 

Fresh build so it has street tires on it, Losail Doha track, i'm a slow mid pack expert pace

 

Ah so you aren’t even in the ballpark of a good race setup. The stock geometry isn’t great, especially on fast flowing tracks. The stock front end isn’t long enough in my experience. And who knows if the springs are within range. It’ll be best if you can find a good suspension tuner to sort the geometry.
