Back when the Rm were first hitting the shops we purchased the Ex gary Adams RH 250 for a friend Peter Simmonds brother in law of Sammy Skilling i think. Hell that was a fast bike a stock RM 250 a wouldnt blow wind up its pipe on a smooth surface but would soon send to the lower places when the going got rough. Chris Oldfield had one of the rh75 i think it was quick as well and i think if they were put over the scales the RH would have seemed like a feather compared to an RM that was how it seemed when riding either. the magneto on the rh was just a work of art but if you didnt dial in the timeing just right hell it would launch you. i remember the first time we took it out it kicked back a bit to much advance and tore the side out of an Alpine star alloy shin guard boot. Melbourne Motorcycles were i think clearing all the new RH and RN73 -74 just before the RM landed. I picked mine up on release night and it was the only RM 250A at the Vic Titles at Wonthaggi the only other RM was Hermans RM370.
I still dream of owning anather RM 250 A and a RH of some description. I dont know what happened to that RH ill ring and ask Pete some day
