I run 32-34f snd 34-36r cold set pressures depending on the weather, so much better! I did try 28f and 32r but it felt sluggish and squishy on initial tip in...

After trying Diablo II and Sport Demons I'd say the GPR300 is the best tire for this bike. It gives the bike a much lighter feel than Diablo II, very flickable and maneuverable while maintaining high levels of grip. Warms up very fast and wore mine down to the edges in no time.

Hard to comment on longevity as I have not been keeping track but it seems to be holding up very well. If I had to guess I'd say I've put over 3,000 and there's still plenty of tire. This will be my go to recommendation for anyone upgrading from stock. I was able to keep up with my buddy on this GSX-R 750 in the twisties no prob.

I just picked up another R3 and I will probably put another set on mine. They always feel great in the canyons and they seem to keep a nice round shape for me without a flat spot in the middle. I do agree they heat up quick. They are a wonderful all around tire.

I have been temped to try the Bridgestones.

I tried out the Bridgestone S20 Evos. They stick thats for sure. I will be going back to the Dunlops. Feel superior to me.

The S20s feel heavy and lots of drag with the soft compound. They dont track as nice as the Dunlops on the freeway.

If you are using your bike for 90% canyon riding I would run them otherwise for everyone else the GPR300 is a far superior all around tire.

GPR300's come perfectly balanced and you can tell the difference instantly despite the S20's being balanced and installed by the Yamaha dealer.

Once the GPR's heat up on the sides they have very good grip not excellent. The extra mileage is worth it too, I can tell the S20's are going to wear out much much faster.

Feels slower overall more rotational mass on the rim is the feeling probably just more contact with the road. Poorly balanced tires have some nice wobbles in them, and needed a string of weights to balance. GPR300's leave you with a clean rim and no weights.

I am late to the thread but I finally got the GPR 300 fitted into my bike but I modded the sizing a bit.

Stock Michelin was 110/70 for the front and 140/70 for the rear.

I went 120/70 for the front and 160/60 for the rear. Instant difference. Handling on corners feels much much MUCH better instead of the feel of it wanting to fishtail. Difference in speed is barely noticeable... Talking about less that 1km/h (0.621 miles/h) difference.
