Good point about changing up too early. That is even more of a factor on a Sport. Perhaps it has had a lumpy cam fitted at some time in its history?harrymuffin wrote:What rear chain wheel have you got fitted? If you are in top with too small a cog you will be below the power band. Have you tried droping into 5th and letting it rev up to around the 8000 mark then dropping into top for a bit more? May be of interest to you, but a bloke rode his Strada up from London the scenic route, the first section on the M4 and holding up lorries, then proper roads with a couple of big down hills and complained to me on arrival that the bike would not rev with a top speed of 60ish. Checking his gearing, he had a 34 back sprocket fitted. Whomever he bought the bike from had a misguided notion that the higher the gearing the faster the bike would go! I put the correct 38 toothed cog on and had no problem in breaking the speed limit and more.
In fairness, my claim to the 80's two up was back when my first Strada was almost new, and I and SWMBO#'1 were both fairly svelte.
Vagueliers have earnt their reputation, but it could be that this one is erring on the side of pessimism, not optimism. I did have the speedo on my R90/6 sort of officially calibrated by Thames Valley Police not long after that. Three figure speeds on that were genuine.
I run the 2C/375 on 14/38 (IIRC, must check). I tried a 13T front for a while but it was too 'busy' at motorway speed.
