Overview
The RD 80LC was the baby of the family, a bit cheeper to insure falling in to the sub 100cc group. It sold for just 2 years, It was not that popular a little spindly and when you could have the 125 for not a lot more wich had a big bike feel about it why go for the 80lc. Still quite a few did get sold and now days they are very rare to find and when you do come across one its usually a shed. They had a iron barrel not an alloy one like the rest of the family. Quite a few people put a 125lc lump in to the frame and they really did fly. I had a friend who did this after crashing his 125lc and picking up a shed 80lc for £100 he easily fitted the lump and everything over the weekend. It was so fast it left my MK2 125lc standing.
