I had a CZ250 for a short time "back in the day" and the thing scared the hell out of me. I imagine that this thing would scream like a scared ape. I love cooling fins as long as my hand. Beautiful bike.
Sorry for the slightly grainy pic but those Webco cylinder heads alone make this bike worth a mention. They are THE best aftermarket cylinder heads for the RD's (yes better than DG's) but extremely rare.
