Triumph Racer – ‘Stiffy’


Posted on April 28, 2011 by Scott in Café Racer, Classic. 15 comments

There’s nothing more intriguing in a bike build story than a mystery, and this here little Triumph has it in spades. See, no one knows exactly what this bike was in a previous life but the smart money is on a rigid dirt tracker. The motor and frame were acquired with a large stockpile of old British dirt trackers and parts that Big D Cycles bought last year; “this bike came out of Les Edwards stash” says Jerrett Martin from Big D. “Les was a famous tuner and builder of dirt track bikes out of California. He owned the Triumph/Suzuki Shop Cycle Imports. A lot of famous riders got their start riding Edwards’ bikes; Gene Romero, Mark Brelsford, Dave Hansen and many others. Dave Hansen rode an Edwards’ bike to Triumph’s last TT race victory at the Houston Astrodome in 1974 (pictured below). In that race, Hansen beat king Kenny Roberts, who was on a Yamaha.” When Les retired he moved his large collection of motorcycle goodies to south Texas. When he passed away, Big D Cycles bought all the race bikes, motors, frames, and spares that were in an old metal barn on his property.

Affectionately named ‘Stiffy’ because of the hard tail (not because that’s what you get when you see it), this bike has a list of mods longer than Kenny Roberts win sheet. Starting with a close finned 500cc T100 Triumph motor, billet nourish crank and lightning connecting rods from Thunder Engineering. Custom ported head with extended intakes and dual plug set up. Rob Newby belt drive conversion, exhaust modified by Big D Cycles from a period Triumph factory race kit pipes and megaphones. Triumph racing fuel tank which is also from the original factory race kit. Tri-spark ignition set up with a BSA front brake setup. “Many Class C guys did this back in the day; it was the best brake setup you could run at the time” says Jerrett. The tail section and sub-frame are dirt track components and the under-seat aluminum oil tank was made from scratch and fabricated in house.

The motor was built and tuned by Big D Cycles owner Keith Martin. Ryan Ambrose did the majority of the fabrication work, and also races the bike like a demon. Ryan recently rode this bike to two Class C victories at the Lone Star Classic AHRMA races in Cresson, Texas. “Stiffy dominated the field both days, passing all the bikes in faster classes that were girded in the first and second waves.”

Big D Cycles plan on racing the bike again in the near future, and hopefully making the ultimate pilgrimage to Bonneville to test ‘Stiffy’ on the salt. Check the very tumescence Big D Cycles blog for loads more beautiful projects and vintage photos.

    I'm in love

  • bum

    beautiful. but the silver heat shield on the pipes looks out of place

  • Ratchop

    Well bum… good thing it serves a purpose instead of just sitting there looking good.

  • @bum I tend to agree. In a purely visual assessment, it does look a bit tacked on.

  • I want it now please.

  • I love this bike..

  • hangaround

    I'll take one now and another one for take away please!

  • chris simpson (cjs cafe racers)

    This is a simply stunning build id love this in my collection! Im sure people are going to tell me im talking rubbish but i think the paint job on the tank isnt as inkeeping with the outstanding standard of the rest of the bike? Just looks slightly less hight quality and more of an after thought.

  • Heat shields were necessary due to the routing of the high pipes. A pair of boots would not last too long without those shields there. These pictures were actually taken before the paint was pin striped. The paint has a very faint metallic base and looks better in person. Thanks for all the feedback on the bike.

  • If someone doesn't make a stiffy joke soon, I'm going to explode…

  • G-Man

    It has two wheels, oozes Kool , and got a reputation what more could a custom builder ask for!!

  • Vince in Dallas

    Awesome bike! It looks good and it can back it up. Good to see a bike from here too!

  • Bob

    It not only looks great, it's a winner on the track….fast and handles beautifully!!

  • BUBBA

    Beautiful, can someone tell me:
    1. what is the 'tray' for under the motor?
    2. have the motor covers been powder coated? or painted silver/pewter?
    Thanks. Bub

  • The bike has an aluminum belly pan fitted to the frame below the motor. This pan is for capturing any oil the motor may leak, preventing it from oiling down the track surface. These pans are mandatory in most road racing organizations in America. The primary cover is off a Norton Atlas, and it is powder coated. The other covers are hand polished.
