I am coming up on 2k miles, I don't think I'll get more than another 1000 out of these OEM tires. In the past on my ZX-10R I used Pirelli Diablo Rosso II's, which hold up really well mileage wise and are still plenty grippy. Unfortunately that tire isn't made in the H2's stock size of 200/55/17. Closest is 190/55/17 or 200/50/17.
Would the 200/50 be a problem at all?

The Evo R was the recommendation from the lads who set up Hilliers H2R for the Isle of Man and his race bike. Won't mention how the senior race went as not to spoil it for those that haven't seen highlights. Get in there !!!!

Reportedly the new premium bmw with its 200 55 can experience tc issues with a different size I haven't heard anything about h2

"200/55/17"...nope...H2 has a factory 200/50.

I'm running a 190/55,have been for two rears now.This'll be my 3rd.She's gripping fine,and cornering like she's on rails.I'm riding TC 1.No issues at all.

Has anyone tried a 180/60? Visually the 180/60 and 190/55 are extremely close...


Out of curiosity, did you do a GPS check with either to see how the speedo accuracy if affected?

A 60 is not really a good street tire;for track use sure its a great...not so much on the street.

With bikes that use wheel speed sensors changing the circumference of either tyre is what will cause a problem with traction control, speedo etc. As long as the front-to-rear circumferences are the same as the OE there shouldn't be a problem. Obviously there's a tolerance, plus or minus, built in for wear. Changing the profiles should only affect the handling.

The specs on the site say 200/55, and I just confirmed on my bike.

I have done 1,000 ks on my metzler M7RR tyres and they perform really well considering the roads here are cold and damp im pretty happy with them

This thread is a year old ...

... but given that it didn't really have a definitive answer in it, I just got back from putting a set of Dunlop Q3 on my bike, and the rear was 200/50-17. I questioned this at the shop but they don't have a 200/55-17 so I took it anyhow.

Answer ... Nope. Traction control on level 2 doesn't like it. Moderate acceleration from a stop - well within actual traction limits - results in TC cutting spark erratically.

For now, I put traction control back to level 1, and it seems OK. But obviously this size is outside what the traction control is calibrated for.

In theory, 190/55-17 is closer in rolling diameter to the stock size and I should have insisted on that instead, in the absence of 200/55-17. I haven't decided whether I will get it changed ... likely depends on whether the shop will do anything for me, and that depends on whether they have a use for a 200/50-17 tire with about 80 km on it.
