i guess I will give the SP V2 oem's a go as there not a pure race setup.
May have just been the torque I think. The pressures were good and the suspension had been sorted by Laurie Smith prior to this trackday. Could have just been me as well, this was only my first double-header at PI so was still getting used to the track.......but I just never got comfortable on the SC's......Jonnymac wrote:.....Gos I think it was your suspension or pressures. Maybe the torque of the twelve???.....
thanks for your info mate.Been a while since I posted here but newer grounds might need to be found.Gosling1 wrote:May have just been the torque I think.

In any case, at the 8 hour at PI in 2011 we chewed through supercorsas on the 675Rs. By chewing through, I mean, we'd have been lucky to get a tank of fuel (~45 mins) out of a rear. Had to drop 2 spring rates at the back to get them working great (3 tanks for a rear and 4 to 5 for a front) - that was from stock, and none of the riders were what you'd call svelte. Few others in the pits were suffering from the same thing. Suspicion is that they're a bit softer a construction tyre - so they end up moving around too much if the back is stiffer than they like.
Chucked them on Stace's RGV and they're great. Haven't dropped spring rate but did back the damping off a touch on the back up at Wakefield due to how they appeared to be wearing. Harley from RB had to drop some back end out of his rvf400, for much the same reason. His words were 'feels like the bike has a hinge in the middle and its all flappy at the back'. He rated them more on the RGV, fwiw. Having ridden both his RVF now and the RGV, the RGV is definitely a lot softer at the back... it's a shade lighter, too.
I'm pretty happy with them on the few laps I got on the RGV, bags of grip even compared to the really pretty good Dunnies we had on it before.
Conclusion: great tyre, might need some setup tweaking to get optimum results... if they're softer in terms of construction (not referring to compound) then maybe they work better on smaller/lighter things than a 12? Thoughts on them being softer/needing a more compliant rear end are just a theory I have; not sure I have enough data to support it just yet
They definitely need treating like a proper slick though, they just happen to have a few bits of tread pattern cut through them here and there.
Thanks for your help mate , its much appreciated . I can totally understand where you are coming from but my bike is a fair bit lighter than the standed product + i only weigh around 85/90 kg suited at the moment and only going the SP series . Thanks again matesupamodel wrote:Been a while since I posted here but newer grounds might need to be found.Gosling1 wrote:May have just been the torque I think.

No offence meant Gos . Unfortunately for me, looking at Gos is pretty much looking into a mirror that shows me what I'll become in 10 years. 'cept with more Suzukis.MAXUMIS wrote:HaHa awesome mate , he is a big bear
