    180/60 Rear Tire

    Anyone running a 60 profile in the rear? If so how does it effect
    the handling of the bike.

    A 180/60 would be taller than a 190/55, nominally. Switching tyre model / brand might cancel some of that out (or exaggerate it). Fewer options in that size, though, from what I could see.

    I've got a 190/55 on my Shiver and the turn in is much better than the 180/55, but the profile of the M7RR means it kind of feels like it turns with the rear, i.e. the rear sits onto the "shoulder" quicker than the front, making it feel like it kicks out on turn in.
    However, the reason I mention the size, is there's also not a lot of room left in the Shiver's swinging arm, especially if you're running a larger rear sprocket - my hugger doesn't fit either.

    There could be more clearance in the Dorso swinger.

    I might try a 190/50 next.


    This is all on a 6" rim - the 2010+ 750 Shivers have a 5.5" with a different sprocket carrier, which I don't believe the Dorsos ever got? Should fit though, with the right parts (sprocket carrier, spacers, sprocket?). I quite like my OEM forged wheels, which only come in 6" flavour, so I'll be sticking with some kind of over-sized tyre I think.

    (It's actually one thing I'm looking on with interest at the new 660 bikes for - there's a new, noticeably narrower 5 spoke design running a 180/60 tyre on the "RS" prototype)

    I think a 190/50 will make your "turns with the rear" feel worse.

    It'll flatten the tyre's profile a bit, which will make the transition to the sides less steep, so I think it'll go the other way. That's the main issue with the 180/55 on the 6" rim, it's too flat and too sluggish. Hence their introduction of the 5.5" wheel.

    ah ok, the transition is getting to you. I thought you meant you were running out of tire.

    I have the metzeler 190/55 and I've run out of side tread on the track so I'll be looking at the 190/60 next.

    I'll have to say I didn't feel like the rear was doing anything weird... maybe it's your suspension setup???

    Not originally I don't think, I'd only lowered the fork clamps by two lines and maybe had a touch extra preload than was necessary (for sag) on the rear. But with the much shorter V4 forks now fitted it's arguably less noticeable, or it might be the wear showing through. It was great at first, with the tyres, but it's just distracting now - might just be me. I don't think it bothered me on track as much as on the road, come to think on it.

    I'd also prefer to run as little tyre as is necessary, for acceleration, since the bike is relatively overweight and underpowered.


    190/60 is definitely large! I guess there must be lots of room in the swingarm? It'd look great, at least.


    Have you thought about trying something with a more sporty profile, like a Supercorsa? (Pirelli and Metzeler are very similar in feel at the sporty end of things, related in fact).

    One thing I noticed is how much more of the front tyre I was using with the suspension / geometry changes I made.

    Looks good but a parallel twin, might as well buy a Ninja 650.

    Or a CBR650... I'm sure the RS would be far more special than any of the Japanese bikes. Aprilia's are far more rare!

    maybe i can go that route as well. On something like my 3rd or 4th rear and I've yet to find a rear tire (on the aprilia) where I haven't run off the edge early even on the street (front is fine). This 190/55 has been the best so far. I've tried 180/55, 190/50, 190/55. maybe you're thinkin right that it's a metzeler thing. I'll have to look into the pirellis.
