Big? - heads & barrels off Reliability - Should be no difference in reliability or servicing Why? - Nelly's 854 was out dragging a 996 on the motorway towards Assen last year....... Models - ???? Benefits - see above and a big plus if your bike is clean & set up how you like it Cost??? - dunno but if combined with having a service duemay slightly reduce costs overall It's fully reversible As for the other bits, Nelly can fill in the gaps |
