Pirelli WSBK 200/65 Tires for Canyon riding ?

Big fans of wsbk and they’re using the tire so figured if the performance is better and the tire works why not give it a try. Like using your favorite athletes tennis racquet. Figured we’d give it a try if it was doable and safe.

I hear you, but re-read the thread. There is a lot of helpful considered info here from people with a lot of experience riding fast on Panis. Some of us are young, some race,some are reckless and some of us are old, but there are no old reckless riders here because they are all dead.

Amen. .... happens. And that mv squared thing can be really harsh.

I'll try again The short answer is dont use slicks on the street for any reason whatsoever regardless of compound unless you are a munter. Pirelli Supercorsa SP's will get you within say 10-15 seconds of the outright lap record for the class if you are any good;
Sylvain Guintoli at Donnington Park on a bone stock GSXR 1000 with street tires 1:37.5 Jonathon Rea on a WSBK Kawasaki with slicks blah blah etc....1:26.23

Dont take my word for it:


and heres rea losing it on slicks

Ya I get that. That's cool. It makes sense for so many things, but not everything. For real, I'm not trying to give you a hard time. So I was asking why the super wide tire because that huge tire is actually slower and harder to turn. I don't know why anyone wants to run the 200/65. Anyone try them? There is so much in motorcycling that is opposite instinct or obvious logic and this is an example.
The wider the tire, the harder it is to get to turn. Big bikes use the wide tires for stability and tire wear, compromising loosing speed into and out of corners. The bigger the tire, the more rolling weight and the more un-sprung weight you add, which means the more gyroscopic force you add. That all means it makes it harder to change directions, accelerate and decelerate.
This is why the 600cc class racers at Mugello are capable of sub 2:min laps with HALF the horse power of the SBK class, with a top speed of only 220 - 240kph. The SBK are only a couple seconds faster and they're going past 310kph. The small bikes go through the chicanes like they weren't there. The difference is huge.
It takes a while to get to know people on this board and there's a lot of .... measuring, but there is also mind blowing amounts of knowledge we pass around. I get blown away weekly. I hope you can have a little patience with us. Ride safe guys.

Watching Jonathan Rea catch highsides is exactly why everyone should ride dirt bikes first. In the dirt you're constantly losing one end or the other. Snapping the bike upright and letting it run off when you need to becomes a muscle memory thing. Wet grass or mud on slicks don't slow down.

As someone who has a stack of worn out 200/65 SC1s and SC3s from last year, here are my thoughts.

The 200/65 slick is much taller(672mm diameter, 10mm taller) and only slightly wider(202mm, 2mm wider) than the 200/60 slick.
The 200/60 Supercorsa is much closer in size and profile to the 200/65 slick since it is 670mm diameter and 200mm wide.

For me the 200/65 slick lasts the longest and has the best drive grip, the 200/60 is the lightest and has the most stability/slowest turn in since it has the roundest profile, and the 200/60 Supercorsa turns in the fastest with the most triangular profile. I happen to like the 125/70 and 200/65 combo the best.

Compound wise, the SC1s:

• Have a narrow temp range
• Require warmers
• Have piles of grip for a few sessions, then drop off to slightly better than SC3 grip
• Don't last long at all on a V4.

The SC3s:

• Work over a really wide temp range.
• Do not require warmers but are happier with them.
• Last a long time for Pirellis, but they don't last as long as Dunlop slicks
• Don't have sprint race grip at the start but also don't drop off as dramatically

I've run the SC3 superbike slicks without warmers occasionally, and while they require a good warmup lap, they're not much slower to warm up than Dunlop Q4s or other track focused DOTs. I would not run the SC3 slicks on the street as the Supercorsa profile is close enough.

The answer I have been searching for the the whole time. Thanks for the insight wortdog.

You guys have it all wrong. The answer to running slicks on the street is to run the SCQ compound. They have the most grip and therefore should warm up the quickest and no lose heat. Also tire warmers are for n00bs. Real riders warm their own tires up.

Also why stop at 200 width tires when you can run a 250?

Super you are way behind in the current poser trends (you need to hang out more at your local poser establishment). Blued Shinko's are the current rage. Slicks are so blase.

Excellent reply by wortdog, hopefully our streetracers dont think that its still a good idea to run slicks but its a free world and they can do whatever the want. I get the impression that the OP hasnt tracked his bike, if not I trust that he does a few days. What doesnt come across in WD's reply regarding warmers and them being optional at times, is that the track environment is WOT and max brakes at every single opportunity the entire session. It''s a completely different experience to street in terms of available grip and predictability.

Personally I love the coffeeshop posers. My last 3 ducati's were purchased used from LA posers. They buy all the trick accessories, like full exhaust systems and then never really ride the bikes. Just got to wait till they get bored (or need the cash). Perfect guys to buy from. Motors are gently broken in (good for the valvetrain) and the tires are always pristine.

I feel attacked

everyones doing it

I once saw two men kissing. Until now, that was the most gay thing I have ever saw.

Wait is that snow? Somebody likes short trail.

Unfortunately I suffer under the delusion that on the very next session I’m going to be a very fast racer on the pointy end of the expert race group…

Right along with the rest of us.
