Posible standard for the R3 would be:

Front 110/70-17

Rear 140/70-17

Good choice:

Metzeler Sportec M5 Interact
Dunlop Q3
Pirelli Rosso Corsa
Michelin Pilot Road 3

 

I am guessing we should hope for one of the bottom 3?

 

im a big fan of Pirelli tires, on cars and bikes. looking forward to having these, hoping we get them

 

I am familiar with tires from michelin, dunlop, and pirelli.

dont know much about metzeler.

 

Never heard of them, not sure if I would by choice go for them. If they come on a new bike I buy I'll try them out. Best to go with brands you know produce good products

 

Metzeler is a German company been around 1863. Pirelli and Metzeler joined forces a few years ago. While Pirelli marketed more toward the sporting side of motorcycle tires Metzeler will edge closer to the cruiser and touring riders who love high-mileage tires. Of course, the Sportec M5 Interact and Rosso is about the same compound.

 

I guess thats why i never heard of them, never ventured out into the cruiser market, always had my eyes on sport bikes.

 

Dunlop Q3 or Pirelli Rosso Corsa! Great grip but mediocre longevity when pushed hard. Lighter bike may help a little!
Tire pressure is of concern too. I like 29-30 for canyon riding!

 

Let try to figure this out logically
Gw250 tire size front 110/80/17 rear 140/70/r17
Gsr400 front 120/70/r17 rear 180/55/17
Gsr600 front 120/70/r17 rear 180/55/17
Ninja250 front 110/70/17 rear 130/70/r17
Ninja300 front 110/70/17 rear 140/70/r17
Ninja600 front 120/70/17 rear 180/55/17
So now let see the possibilities for the yamaha
Yzfr3 ??????
Fzr( I know its old) front 110/70/17 rear 140/70/r17 Yzfr6 120/70/r17 rear 180/55/17

So looking at that... On the cheap side worst case trying to save money. Yamaha would do front 110 and rear at 130.. But with at much power it wont happen .there is a strong possibility it will get a 120 front and 180 rear. Just like the r6 less inventory less Hassel easyer for the company. If they wanted to make the tires look more proportional to the bike they should go with 110 front and 140 rear... ... I hope the go for more grip at 180

 

Michelin Pilot Streets

FRONT: 110/70-17
REAR: 140/70-17

In this article the bike has Michelin tires, and it looks like a 140 rear. Tire brands change in different markets as you know. It's one place they save money. Lots of new bikes come with Bridgestone or IRC tires these days. I would prefer Michelin pilot pures.

 

I beleive they are going for 110/140 like the FZR on 17s.
So long as they are decent all weather tyres at the time of release then I will be happy - not that standard IRC stuff you see on many bikes.
Michelins would be spot on. Make a huge difference to confidence.

 

OOPs. They have the specs out now and it is a 120/180. I have a 180 rear on my FZ07 and the photo sure didn't look like a 180 rear, but Yamaha now has the tires specs on their website.

 

This is in keeping with their one-upsmanship over the Ninja 300. Almost everything is a little better...bigger engine, more hp, more torque, lighter weight, larger rear tire. I'm surprised they didn't put the redline at 13,000 vs. 12,500 for the Ninja 300 too. No doubt in my mind Yamaha is going after the Ninja 300 market mainly. They will catch some CBR300R and KTM RC390 sales as well...provided they get the bikes out instead of doling them out slowly one or two per dealer in 2015. If I wasn't planning to trade in a bike, I would already have worked out a price and put down a deposit.

 

Depending on which Yamaha site you go to, the specs list the rear tire as either 180 or a 140, so I'm not sure now. I'm thinking 140 though. The photos I've seen all look like a 140. I was on the Alamo Cycle Plex, San Antonio site and clicked on Yamaha motorcycles, then found the R3 and specs. That's where it lists the rear as 180. Might just be a typo.

 

okay so now we know the tire sizes and make.. 110 F 140 R michelin pilot road(not radial)

My question is can you size up the rear? if so how big? is it worth it? And what do you think of perelli corso, they are radial right?

 

Probably could go up to a 150 rear, but any bigger would deform the tire on the narrow rim. I put a 170 on a rim that was factory shod with a 150, and it will have permanent "chicken strips" because the narrower rim pulls the carcass inward. I would have to lean like Mark Marquez to scrub the tread at the edges. Next tire change I'll go down to a 160.

180s are meant for 6" wide rear rims; the R3 has 140 section tires on rims probably 4 1/2" wide. 180mm minus 140mm = 40mm or 1 5/8" difference in tire/rim width.

 

cool... thanks man. I think I'll stay stock size and put some perelli's on it

 

I think it may be worth a shot to try and get a 150 on there, i'm sure others will try soon enough.

 

So has anyone actually measured the rear rim width? I wonder if it's the same as an SV650/EX650 which take a 160.

I want to get a set of Pirelli Rosso Corsas for the track, which would also mean getting a 120 front. I can't imagine that being a problem unless fender clearance is super tight.

 

It has a 4 inch rear and 2.75 front, as per owners manual.
takes 140/70 & 110/70
DR2 & S20EVO come in those sizes, they are well proven wet or dry race rubber for 250/300's
then SC1 and BT003 are the next step but dry conditions only.


Unsuitable rubber designed for big bikes will only slow it down, and give poor grip as you wont keep any heat or use the entire surface area effectively.


*Its the rim that makes it look wide, not the tyre.

You're already replacing the stock Michelins with those?

 

My Bridgestone 003's came in cpl days ago,,,I cant wait to take off these Bullshit Pilots..I simply don't trust them with the type of "Spirited" riding I like to do.

 

Ive always say I wouldn't put Dunlops or Michelins on my wheelbarrow,
but Shinkos!? crikey , even Hyosung riders don't like their std death hoops.
They make IRC road winners feel like MotoGP tyres.


Brands that begin with P, or B have 3 options at 3 levels and all are perfectly capable for any rider here.


Stick to 110 and 140, this is most important.

 

I've put around 250 miles on the Shinko SR 880/881 in 2 days. Still alive : ).

They do change the ride of the R3. Much more comfortable over rough pavement. More stable and planted feel from the front and rear. Flatter profile makes the bike steer slower but has more stability holding the line in the curves. Depends on what you need in your ride. Harder compound for sure over the stock tires. If you're riding from coast to coast all freeways get these tires. Sport touring are the Shinkos.

 

Are the stock tires on the R3 as bad as all the reviews say? It's my first bike and I really have nothing to compare them to. If so I would get them changed to a decent radial set before I pick the bike up. I'm not ever going to be at a race track with this thing but I want it to be as safe as possible.
Thanks.

No.

 

where are the reviews?

 

Almost all the more in depth youtube reviews fault the bias ply tires for holding this bike back from its full potential. Just curious as to how that translates to the real world for those of us who won't be at the track.

 

...cause they're new, but they are decent tires. I only wish they were wider. That's a upgrade I'll do when these even hint to the idea they're ready to be replaced but not going to spend that money now for no really good reason (I don't ride track, but I do some wicked canyon riding...).
