Have spotted a mid 90s classic Laverda for sale. Its a Formula 668 with all the goodies and with low Ks. Does anyone have any thoughts or experience on this model Laverda ? I checked some UK forums and they suggest buying a spare motor to keep ANY Laverda running which sounds a bit harsh. The bike is a Zane version. Or should I look at the 93 zzr1100D that has also taken my eye ? The Zed looks big and heavy compared to the Formula.
