Nice looking tire special made for small displacement cycles. I just purchased some s20 in the stock size. getting delivered today.

 

The Bridgestone S21s are out now but they don't have a rear in the stock 140 size yet. They're pricier, too, at around $143 for the 150 rear.

Plus, if they're like the S20s they also won't have the new triple compound on the smaller sizes....

 

Getting them mounted. Will report back soon.

 

Awesome, is that just the rear tire or did you get both front and back?

 

Not really looking for comparisons on this thread, thanks. Bird - feedback appreciated - right at $200 for the set? .

 

Got them mounted today. More grounded. Tracks better.

Not enough miles yet just cruising. Will report back after a break in and a real test.

More rigid over bumps but I expected that. Less bounce.

Front and back, added better images.

 

What pressures are you running?

 

30F 35R cold. Guy that mounted them runs an RC390 in the same areas I ride and said he got it dialed in fairly good.

I took it to a Honda Kawi KTM dealer. First time they had an R3, they liked it.

The test drive was pretty long for a tire change. He took most of the sheen off of them. :laugh:

 

The difference on the freeway is beyond what I could have imagined. I now know what the poor feeling was while riding. It was the tires. It feels amazing now. Not the greatest tires in the world I get it they are old but I am used to them and I like the way they wear.

I would recommend to anyone looking for a mod for their bike to do tires before anything else. Just wow.

I am actually carrying more speed, its weird, feels like I am going slower. I was just doing a steady 82 and it was very solid.

I also added a taller windscreen and between the two its like a new bike. I was in wind gusts and they were affecting me much less than before.

I think I am over inflated in the front.

Vertical lines in the pavement dont cause me so many headaches now, I can just ride with them or over them.

 

Since you're first out on these, I'd be interested in seeing what maybe 28F/32R cold would do if you're game. Better, worse?

 

Ill give that a shot tomorrow and report back.

The only real area where this bike came up short for me was at freeway speeds in nasty socal traffic. This is exactly what I needed.

The bike used to bounce all over the road, the tracking was all over the place. Almost dangerous.

Edit: F it I am so happy I am going to go try lower pressures. This is the best mod I have done yet, thought it was the power commander but nope this is clearly the best.

On to suspension next. Coming from Ohlins on my last bike this is junk.

 

Just curious, what made you pick this set instead of the Rosso II's or the S20 Evos.

I rode on the Frwy last night and knew exactly what you were talking about and will be riding on the interstate for two straight hours next month and need more stability.

 

Longevity and prior experience with them. A few of my friends use this tire exclusively and it came on my R1 stock and was a good tire. Good mileage and grip.

I find them forgiving when you wear them down. Dunlops for me in the past felt the best all the way through the tires lifespan if that makes any sense.

I bet some of those certainly could be better tires but I don't like to change every 3500 miles. I understand most not having interest in this tire.

Lowered the pressure and hooked up nicely especially on a few freeway ramps passing people. I would not go any lower than that on the pressure thats for sure. I would probably go up 1 on the rear, but I will wait for hot days and see how it gets real hot.

Easier to ride, way less shock, but transitioning side to side is a bit sluggish. All normal stuff you would expect. Lots more drag, bigger contact patch.

I think any radial tire would be a vast improvement. I can finally hold a line and just relax and ride instead of being on Mr Toads Wild Ride.

 

Sadly this ride has been removed and replaced at Disney World

 

So I wonder do the 140 h get the grippy compound or the mileage stuff.?

 

Hard to say. I don't have enough miles to gauge longevity but everyone that touches them says they feel very sticky. I like em.

Unlikely to see high mileage out of them. Had them nice and round edge to edge usage then took a few higher mileage trips and see wear to the middle.

 

Curious how these would work as rain tires? Everything I have seen for rains is in the GP sizes. 100/70 17 fronts 125/70 17 rears.

 

GPR-300 rear for $86

The rear is now $20 cheaper on MotorcycleSuperstore going for $86.04. A set comes in at $181.82. About the best price I've seen for tires in the past few months.

 

I have a set of these I pulled off my 390 after I bought it, will let them go cheap if anyone is interested

 

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.
