Not really, riding a Quad compared to a Trike is sort of like operating a ski boat versus a jet ski in my experience. I know trikes can be scary but they are also easy to bail out of or at lease use your feet for stability in some cases, wheras every time i've been on a quad i've felt like i'm in it rather than on it - more like a tractor than a bike in my experience anyway. Quads are a better farm vehicle, but as a recreational thing not anything like a trike.

Where in the frame is the oil tank on the RFVC XR500? We only ever used the old wet sump 1979-1982 engines.

Do the 500cc RFVC engines suffer from the same head cracking problen as the 250 variants? I remember I had a 1984-5 XL250R and could not find a good head for it.
