June 2007 Reader's Bikes - Trackmaster

Albeit ""vintage"" dirt track racing

Jun. 01, 2007 By Rick Sieman
After spending the better part of 40 years working in management for one of the world’s largest airlines, Dale Johnson has come to a point in his life where he finally has the time and the resources to pursue a dream that he’s had all of his life:  Dirt Track Motorcycle Racing!  Albeit “vintage” dirt track racing as a  “senior”, the excitement and the desire are still there (not to mention a modicum of fear as well). 

About a year and a half ago, Dale got serious about pursuing that goal and bought a 750 Triumph Trackmaster.  It was pretty much a “run of the mill” 70’s vintage used race bike.  The bike had a lot of the  well known “trick pieces” already, Barnes “quick change”  hubs, Ceriani 35mm road racing forks,  ARD  magneto and more.   The bike was “ok”, but really not anything to write home about.  Dale, being very patient and somewhat of a “nit-picker”, spent a lot of his free time stripping the Trackmaster down to the frame and starting one piece at a time, to meticulously clean, polish and in every way create a “silk purse” from a “sow’s ear”. 

After retiring from the airline business Dale found himself bored after only a couple of months and was able to do something else he’s always wanted to do, work in the motorcycle business.  He’s become a very successful motorcycle salesman at Irv Seavers BMW motorcycles in Orange, CA.  Being reluctant to damage this beautiful Trackmaster in any way, Dale has recently purchased another complete Trackmaster racer very similar to this one.  He says it’s going to be his “practice bike”.

As these photos show, he also decided to make the machine “street able”, temporarily at least.  He added a Bates headlight, a taillight and even installed a Volkswagen brake light switch.  All running off of a “positive loss” electrical system, a small gel cell battery provides the power.  The bike was licensed and that enabled him to occasionally ride it on the road to get a handle on any shortcomings and to get a feel for any handling eccentricities. It’s also fun to play with!  All of the “street” items are quickly and easily removable  for the track.

Fuel tank is a Gopher Glass Trackmaster replica.  Dale ended up with two of the tanks and has had them painted in different, contrasting color schemes.  The paintwork was done in Cherry Valley, CA, by Chris McReynolds, the son of an old friend.  Here are a few more views of this beautiful restoration.
