It was very interesting reading back through the old thread.
I think I paid about $1,500.00 for my RH75 back in 1975. I traded a 74 Maico 250 in on it at Mayfairs Suzuki. I bought a RM125S as well later that year. I traded the RH in on a RM250A late in 1975 and then Mayfairs (who I was working for in 1976) swapped the 250 for a 370A early in 1976.
Its funny when you think back it would have been great to keep the bikes you had back then, but money was the problem.
It's interesting to see KTMaico was going to race his RH75. I haven't seen his Maico or the RH on the track yet.
