Ossa began producing the Mick Andrews Replicas in 1971 and was a very competitive trialsbike, this put Ossa on the top of the trials scene.
In Mick's hands Ossa MAR whent on to win 2 European Championships and 3 Scottish Six Day Trials.
Ossa started to get into troubles and with all the factory politics so the obvious happened, when Mick was approached by Yamaha he did a deal and he went over to Japan.
Yamaha had already built a bike, they had bought an Ossa to get some ideas and so Mick would have been their first choice to develop their new trialsbike, the TY was loosely based on the MAR, and they made many modifications to get just what they wanted.
After Yamaha stopped development of their trialsbikes he can not think of anything other than buy a new OSSA to compete in the British Experts, he briefly helped Ossa to try and develop the old MAR models but they desperately needed a new design to compete.
He then collaborated with several brands to develop their models and in 1979 Mick appeared on the Ossa prototype of the new TR model, which featured a development of Ossa’s motocross engine with much slimmer crankcases and a radially finned head. The Yellow Peril looked as though it might be just the bike to put Ossa back on track and when the production version appeared late on in the year things looked good.
But alas in 1979 and 1980 the Spanish companies started suffering from strikes and walkouts and so the trials boom they hoped for never happened for them, and in 1982, the Ossa factory closed down for good. Even the championship Bultaco factory team with its new World Champion, American Bernie Schreiber had to disband in the middle of the season and riders had to find new mounts with different makes.
The reign of the Spanish manufacturers ended.
I have written this from what I recall and with the aid of some old press cuttings that I have, so if you know different please put me right.
