An RD400C was my first bike, followed by a few Lc's and one YPVS. The only one that let me downwas the power valve, went through several CDI's.
Still have the 400 which I recently finished restoring. My other bike is a Laverda 750S. Why ? Because it is different and handles well, and the sound of that twin ! I am looking to replace this as it isn't the type of bike you want to thrahs on a track every second weekend. Rode the R6 and loved it, but down here in South Africa every 2nd bike is an R6. Also for 500 pounds less I could get a GSXR 750. Tough decision.
