Small bike tire question

I'm trying to make it out to the track this year, and in order to do so, I need new tires for my 2011 CBR250R. (Yeah, I also should probably get a different bike for the track, but that's not going in happen in the next few weeks.)

At any rate, I went to order another set of my trusty BT-003's and found that they were discontinued in 2015. It seems that the replacement tire should be the BT RS10's, which have a different compound for the small bike sizes (as I understand it).

https://www.bridgestone.com/products...001/index.html

At any rate, I'm not finding these tires for sale in my tire sizes anywhere. Am I missing something? Did they discontinue the H-rated (smaller bike - slower top speed) version of these tires?

So - any tips on where to find these tires? Or if not these tires, tips for other sticky track tires that are street legal, don't require warmers, and fit my bike?

Thanks in advance for the advice - and sorry if it's a stupid question. I haven't been keeping up on the latest and greatest in tires, and my google-fu is failing me.

Have you considered the new Dunlop Q3+ in 110/150? They are the 2018 KTM Cup spec tire. I've put quite a few on KTM's, Ninja 250/300's, and R3's. They're an excellent tire for the track and do well on the street. Since we're a Dunlop Pro Dealer, you'll also get a $75 rebate per set. The price can't be beat. I have a set at the shop if you're thinking of trying a set.

I put the Metzeler Sportec M7 on my RC390. I did two track days on them plus a bunch of street miles. Nice tires.

Bridgestone RS 10's seem to be the replacement. They do a direct comparison to the street version BT 003.
I'm signed up for the 24th. Can't do the 25th.

Hey Sister C! My +1 is to switch to the Dunlop Q3, great tire and available it appears. Not hating on the 'Stones as they come stock on so many machines, but every time I have gone from them to another brand;, Dunlop, Avon, Michelin....I have been so happy! Your CBR 2.5 is going to be a great bike for the track...better and more fun to ride a small bike fast than a big bike slow...or the ilk. Are you planning on the Ridge or...?

Ran Pirelli Diablo Rosso II on the Ninja 250. No issues on the track. No warmers needed. I think you should be able to run the 150 rear. Unsure of longevity on the street.

That was the tire my RC390 started on. Made it about 7000 miles between 3 track days and some sport touring.

Also a nice tire.

I did 5 straight track days last month on my R3 with a Rosso II 140 rear and Rosso III front. Really, really impressed with both tires, but especially the new III front. Knee-down grip by turn 2 in 70-degree drizzle on Monday and 95 degree heat on Friday. They behaved predictably even when I was probably going too fast for a totally stock "learner" bike. My kickstand is probably half a pound lighter than it used to be.

They replaced a set of Rosso II's that lasted 7000 miles of commuting and 3 track days.

Thanks, everyone. Much obliged! I'll poke around and check these options out.

@Zxtasy, yes, I'm looking at the Ridge with OPRT Aug 24 and/or 25. I do love my small bike, but it is seriously the slowest bike out there. Even the Ninja 250's have a higher top speed than my bike. Still, it's a ton of fun!

So...my bike normally takes a 140 rear. Does anyone have experience with putting a 150 on a wheel that takes a 140 stock? How does the handling change?

Candiya, Not any exact experience but generally a one size up in width may slow down the rear turn in feel, though the Dunlops have a nice profile so that may be a non issue. It should give you a slightly larger contact patch which is good and when leaned over will slightly raise the rear end and make the front feel quicker turning.

2 years ago I went from a 160 stock to a 170 on a Ninja 650 and it still handled plenty nicely.

Have some fun for me!!!

You prolly won't notice a thing except newfound confidence in fresh rubber that gets nice and grippy after a bit. A quick check on a CBR250 forum shows it is done quite a bit.

Thanks, all! I decided to try Pirelli's for the first time - with the Diablo Rosso 2 rear and 3 front so I could stay in my stock sizes. I know it's probably just me being a scaredy-cat, but changing the tire size makes me a bit nervous. Since half the reason I'm getting new tires is to have warm fuzzies about riding the bike, I opted to stick with the 140 rear.

I'm looking forward to my first sticky new tires on this bike in several years! Now to sign up for the track day(s)...

Good call. Wider tire can change the feel of lean in and corner capacity. Best to stick with what you know, albeit, new tires are bigger and will handle different, so be careful anyway.

That said, a 250 at the ridge would be rad! Wide open straights but there are 16 well engineered technical turns on the track. The pavement is purpose built 15 inch thick race asphalt. Youíll have a blast. No mirrors, you learn the race line and the faster bikes will only pass when safe. Itíll be cool.

My tip: Hang widethrough turn 6 until you can see a water tower about 5 miles to the east, then flick in for a super late apex and get a rad setup at full speed into the double apex turn 8 and 9. (I think I got that right). Turn 6 can be really fast! Have fun.

So...in an ironic postscript, UPS lost my rear tire so I might not make the track day after all. At least I'm much more informed about tires, and I'll have fresh rubber eventually!

Oh, and thanks for the tips, @andonon! I've ridden the 250 at the Ridge before, and these are all good reminders about the track.
