08colin Posted August 30, 2011 Report Share Posted August 30, 2011 Hi All might be one for big J looking for information and photo's of the late 60's Diamond trials bike,the only information i have found to date is in Mr Morleys british two stroke book and there is no photo's I have aquired a frame which i was told was a Dalesman which i don't think it is,on rubbing back the paint work the frame looks to have been a pale blue but the rear chain is adjusted by snail cams on the swinging arm pivot it has prop stand mtg bracket on the R/H side the frame is also twin down tube forming a cradle under the engine,engine mounting's look to be for a sachs engine.It looks at first glance like a rickman but they were nickle plated or possible wassell but from the pictures doesn't have the snail cam adjusted rear chain so now i'm open to suggestion's and any help that i can find on the diamond trials bike that was made in Birmingham in the late 60's mini trials bike era,thanks in anticipation o8 Colin.

rockaria Posted August 31, 2011 Report Share Posted August 31, 2011 The Diamond pictured here belonged to Mike Carey from Derby and the photograph was taken at the 'Bull-i-th-Thorn' hotel which hosted the start of that years Bemrose. Coincidentally, this bike was alluded to in an earlier post about John Orme (also from Derby). Unfortunately the bike was virtually destroyed whilst being transported to Clifton scrambles course when a following vehicle went for the overtake just as Mike turned right! Bill Cooper (also from Derby) made a small number of frames based on Mikes Diamond but used Bantam engines. John Orme was still riding (and winning) on his version into the early 80's! I believe the mesh screen on the front down tubes was an owner modification, not standard fitment. Quote Link to comment Share on other sites More sharing options...
08colin Posted August 31, 2011 Author Report Share Posted August 31, 2011 THANKS B40RT AND ROCKARIA THE PHOTO IS A GREAT HELP THE FRAME I HAVE IS VERY SIMILAR ONE DIFFERENCE WE HAVE SPOTTED IS THE TOP AND BOTTOM REAR SHOCKER MOUNTING POINTS BUT THE DIAMOND SEEMS THE CLOSEST MATCH TO WHAT I HAVE. I AM OPEN TO ANY OTHER MINI TRIALS BIKE BUILDER'S OF THAT ERA,ONE THING I HAVE SPOTTED WHICH MIGHT HELP PIN DOWN WHAT THIS IS,IS THAT ON THE FRAME THAT I HAVE AS A LARGE TOP TUBE OF 1 3/4 INCHES AND A SMALLER 1 INCH DIAMETER TUBE FROM WHERE THE FRONT DOWN TUBES ARE WELDED TO THE HEAD STOCK AND WELDED TO THE UNDERSIDE OF THE MAIN TOP TUBE APPROX HALF WAY DOWN IT'S LENGTH IF THIS IS UNDERSTANDABLE. DON'T KNOW HOW MANY VERSIONS AND ALTERATION'S WERE MADE THROUGHOUT THE DIAMOND TRIALS BIKE SHORT LIFE.THANKS ONCE AGAIN 08 COLIN Quote Link to comment Share on other sites More sharing options...
