If Honda is true to form they'll already have an 800 built and are testing it now.
I don't know what taking down the capacity to 800cc is aimed at. If it's to reduce speed, then the manufacturers will just make a bloody quick 800.
I stand to be corrected, but didn't they try reducing the capacity of the F1 cars a few years ago, then introduced 'treaded' tyres, all in a bid to slow them down, then came along a famous Italian red car and a certain German fellow behind the wheel and the lap times started going down again.
It is a shame that Suzuki can make an amazing 1000cc Superbike, put an Aussie on it and win the AMA and WSBK championships. The GXR1000 looks set to take the Aussie championship as well. Hey, that's it, Sukuki have found the answer, put a Aussie on the thing....
