Dunlop 200/50/17 Q2 or Q3's

Anyone tried it yet? Just curious. The 190/55 Q3's are getting great reviews and my dealer has them/can get them at a really good price, so i'll probably go that route.

just a thought but i know the q2 if you can find them are really cheap cause the q3 are out. i could be wrong but you may want to check if the difference in price is that much and or worth it.

i hear the q3 will be in 200 shortly i tried to call dunlop no answer

Per reports i've read the Q3 will be a 200/50 not the 200/55 that's fitted to our bikes. But we'll see.

It is 200/50, not 200/55, so it will radically change chassis geometry. That lowers the bike a full 10mm in the rear!

A 190/55 is a better choice from the perspective of chassis geometry, as it lowers the rear only 5.5mm.

If you're not beating on it, it won't matter. If you're beating on it, stick with 200/55 IMHO. That means either Pirelli Super Corsa SP2 V2 or Michelin Power Cup (I use "C" compound).

There are other 200/55s out there, but they're cruiser tires. Hopefully Dunlop and Michelin will pick up the gauntlet soon and start knocking out 200/55s....but it'll probably take other bike manufacturers using that rubber on bikes with higher production numbers to pique their interest.

I think the Hp4 uses 200/55???

1199, HP4 and RSV4 all use the same 200/55/17.

This is one reason I'm going with the 190/55 Q3. However, it doesn't sound like anyone was daring enough to try a 200/50 on their Pani lol.

+1. Can't really figure why they'd be making a Q3 in a 200/50; what the heck is that for? As for the 190/55's, the new Q3's are taller than the Q2's, so it should actually only about 3.5mm less in ride height than the OEM 200/55 Pirelli per the specs (649mm vs 656mm dia). If the front weren't taller than the Pirelli, the effect on TC would be extremely minimal, and as it is it's fine for street riding.

My thoughts were based strictly on the maths. 200 x .55, 200 x .50, and 190 x .55. Actual production values vary slightly from theoretical, so nice info to have, Steve.

As to traction control disruptions, changes in rolling radius as the bike nears the edges of the tire are likely significant even if the centerline radius is similar.

Yessir; you are quite correct, and indeed the TC is affected at lean. The upright diameter variance would likely be more of an issue triggering front ABS intervention (can't verify since I don't have it).

As for the TC, in my experience (on Bridgestone S20's at present, which measure very similarly to the new Q3 specs in back, bit smaller up front), the TC with a 190/55 on back is between 1 to 2 settings more intrusive than with the OEM tires. Having cut my teeth on dirtbikes, I'm comfortable with the bike moving around; so I ran my TC from off to 3 at most for dry road use with the Pirelli's, and now I run it on 2 or less with the 190 on back. Not ideal, but acceptable for road use where you're not trying to squeeze tenths off lap times. You can still get the rear to move firing it off a corner before the TC reigns it in if you're feeling frisky. Had owned liter bikes in the past, but never had one with TC and didn't think I needed it before I got the Pani, but have grown to enjoy playing with the magic dash light. I have been assimilated!

Just as an FYI - a 190/55 S20 when mounted was 5mm LARGER in diameter than the worn 200/55 Pirelli that it replaced, so it's useful to note that the TC/ABS has to be able to accommodate a good amount of variance even on stock tires as they wear.

that is true

is that a street tire or track tire the power cup that is?

i am on the michelin site. whats the difference in the compounds a b and c i cant find anywhere that it states that. also the va vb or a. i assume its compounds but what are they.

A is the softest, C is the hardest. I run B's all around. The "V" profile for the front is shaped more aggressively. I run them, and would not recommend the V profile for the street.

What he said. I'm currently running a C on the rear and a V A/B out front...just mounted 'em last night after wearing out a C rear B front. I think I like the rounded profile a bit more, personally, but the V puts more rubber on the ground at lean. My "standard" profile tires become "V" profile pretty quickly, anyway, so I thought I'd give 'em a stab on a street bike for giggles.

Pirelli Supercorsa SP: 1400 miles including the restrained 621 mile break in.
Michelin Power One: C rear/B front 1300 mostly rough miles (less expensive and quite a bit stickier than the SPs, and they warm up really quickly...but no longer available, replaced by Power Cup)
Michelin Power Cup: C rear/VA/B front ???? miles (about the same price as SPs, but after that last set of Power Ones, I'm not sure I'll ever buy another set of SPs)

I can shoot pics of the worn out Ones if anyone is interested. The front is absolutely SHAGGED, and the rear isn't far behind!
