I own a 1985 R80rt which I have owned for around a year. It has done around 75K and goes well. I have the opportunity of buying a 1983 R100rt in very good condition with only 49K. I know both these two bikes are very similar with the R100 putting out around 50KW as opposed to the R80´s 36KW and am told the R100 braking is much better due to its twin front disc´s, I would be grateful for any advice regarding the pro´s and cons of these two bikes.
