Biased..but R. Some good prices knocking about at the moment, and engine performance aside, the showa rear suspension is far superior to the sachs on the S4.
S4R is an awesome track tool but ground clearance is an issue (see pic) which can be slightly helped by raising the rear ride height.
S4's still look great though in senna colours and if you could always bag a cheap one, and spend the difference on mods and a 955 conversion..
Yours confusingly..
