Slowly does it There is an old saying about London buses, “You wait ages for one and then two come along at the same time”. To my knowledge, we have never had a report of one of the least-known branches of historic motorcycling, Observed Trials. A few weeks back I received a report of the ‘Pre-65s’ section of the Australian Trials Championships in Victoria from Bob McGlinchy. Then a week later, along comes a report from Colin Sheehan of the Twin-Shock Trial at Conondale, Queensland. You’ll find both of these in this issue. But it reminded me of just what a major part of the sport this form of recreational riding once was, usually known back then as Sporting Trials, mainly to distinguish it from Reliability Trials. In New South Wales at…

letters to the editor

And from abroad… Congratulations upon reaching 75 issues. I first found O.B.A in a newsagents in Manly, September 2008, Issue 9. I was on holiday with my wife Marion (Mazza) visiting rellies and friends, as way, way back Marion was a ten pound Pom. Fortunately or unfortunately(?) she visited the homeland and met and married me. Anyway reading O.B.A. I found it had just the right amount of info. Things like Tracks in Time – places I had never heard of but recognised riders’ names, the ones who came to Europe to race. On returning home I managed to find a company who could get the magazine and also back copies of ones I had missed (1-8). I look forward each month to the next issue. It always amazes me the…

A life in the trade While reading OBA 72 there was a story on Brian Collins, and also mentioned were Harry Bartrop and Stan Buckingham. I started work in the warehouse at Bennett & Wood in the early ‘sixties at Joynton Avenue Zetland (Sydney). They had a great range of spare parts for Holden and Ford and were also the NSW agents BSA and Honda, and they also made Speedwell pushbikes in a factory in Redfern. I worked my way up and after a run on the motorcycle and pushbike counter Harry Bartrop was my boss and a good man to work for. I bought my first bike in 1964, a Honda C200 90cc. I rode that bike everywhere and in 1965 made my first trip to the Bathurst races. I spoke…

Triumph twins – 360 or 76 degree crankshaft? Many a discussion and articles have been written since Phil Irving advocated that parallel twins should have crankpins set at 76 degrees as opposed to the usual 360 degree crankshafts. Somehow, decision makers at the head of the British Motorcycle manufacturing establishments were reluctant to make changes until it was all too late. They failed to address one of the parallel twin’s worst features; that the 360 degree crankshaft, with pistons rising and falling together, is badly imbalanced. The worst enemies of these crankshafts is primary forces, created by the inertia of both pistons as they are forced to slow, change direction and accelerate at the top and bottom of their strokes. Undesirable secondary forces also arise, some acting in an upward direction…

A slip in the night Our feature on the incredible rescue/restoration of the Honda C71Z in OBA 76 unfortunately suffered a technical glitch prior to printing which saw a few lines of text disappear. The corrected story is now on our web site, so if you’d like to read the complete version, go to www.oldbikemag.com.au/honda-c71z-rarer-rare/ Coming up soon we will have a feature on another ultra rare Honda that has been masterfully restored by the Marnix Deibert/Sebas van de Broek team for Mike Buttinger at CMS. This is a RC70F (above), imported to USA in 1958 and raced by the famous Preston Petty, who went on to fame as the producer of plastic mudguards, fuel tanks and side covers as the dirt bike scene exploded. Bill’s award On November 24th, Bill Horsman became the…
