To clarify, do the discs of more modern Aprilias, e.g. RSV4, have the same hub fitting as the older bikes, which are the same as older Ducatis, Yamahas and KTMs?
What ST says. Has it had any sensible chassis mods to account for the potential large increase in power? It tends to help with the laundry bills having a bike that stops when you want it to and doesn't fight back when tipped into a corner. Any pics of the bike? We like pics .
Dunno much about Dyna ignitions (someone who does should be along soon ) but you can get an Ignitec adjustable CDI from Czechia for a reasonable price that will be compatible with the stock pickups. I may have to get one soon for my EFE engine as I think the CDI is playing up.
There's also a bloke in Belgium that makes and sells aftermarket CDIs for OSS bikes but I am buggered if I can find his website .
So earlier switch from GSX1100 is 26mm and fits B12? The switch on my EFE is the larger 36mm type. Like Wraith I used to think that all GSX1100 switches were the same but that does not seem to be so.
