Err, my dad did a test of the RL back in the day....I'll try to remember what I can about the RL.
The motor was very docile, very linear power but not much of it. That's ok considering it was aimed at the entry level rider. BUT it was the chassis that let it down (not my observations I can't remember much about the chassis). In the UK the junked the frame and put the motor in a Whitlock frame. This was the famous Beamish Suzuki and that was very popular.
