Dave,
A thousand apologies

! I read your last and replied as if you were new to the marque...which you are obviously NOT...Doh!!! I should have paid a bit more attention! Sorry.
So in terms of what they're like to ride..... a well sorted 900/944SS will make about 85 BHP at the rear wheel with peak torque around 68ft lbs. With a few necessary mods (particularly a rear shock which provides ride height adjustment) they handle well but the 748R will be a hard act to follow! You might notice a difference in the riding position comfort especially if you're 6ft+.
Apologies again for the previous...I'll get my coat!!

A.
