STG Tracker builds a Trials-inspired Enfield 500…
More than 75 years ago, the 1948 G2 350 Bullet debuted as the first motorcycle with an articulating swingarm, destined to become one of the best-selling Enfields in history. In 2009, Royal Enfield released the Classic 350 and 500 models, which took their inspiration from the Bullet 350 of the post-WWII era. However, the Classics featured unit-construction engines, fuel injection, and electronic ignition (in the case of the Classic 500), and were priced and marketed above their Bullet 350 and 500 siblings.
These bikes have been called “two-wheeled time machines” for the way their style and simplicity of design echoes the Royal Enfield “iron barrel” Bullets of yesteryear. Ren Withnell of Bikes and Travels summarized the riding experience quite well:
“I do feel much more involved… I am riding this bike. I have to give it instructions that it follows. I am not being wafted along on a magic carpet, I’m riding a bike. The motor is strangely awesome. It is not fast, a mere 27bhp. What it is is unstoppable. Whether or not you’re climbing a steep hill it will maintain your speed without complaint or extra throttle. It’s all just a big fat juicy lump of heavy torque. And it will run smoothly at such low revs….”

“The client asked for a 60’s style trials bike, full aluminium.”



Enfield 500 Trials Bike: Builder Interview
• What’s the make, model, and year of the donor bike?
It’s a 2010 Royal Enfield Classic 500.
• Why was this bike built?
This bike was commissioned by a customer, we already made him others.
• What was the design concept and what influenced the build?
The client asked for a 60’s style trials bike, full aluminium.
• What custom work was done to the bike?
New aluminium CNC yokes, 21″ front wheel, aluminium tank, handmade both aluminium fenders, custom-made foot controls, stainless steel exhaust, custom-made aluminium shield protecting airpod filter from BMB Filter, new larger rear shocks, custom made seat with leather, hidden LED turn signals, Technic TK Block tires.
• Can you tell us what it’s like to ride?
Nothing like the old original bike, now you feel the engine and have more control on what you want it to do with a quicker response.
• Was there anything done during this build that you are particularly proud of?
Definitely the foot controls. They seem just too simple, but making them that way was tricky, also changing the original feet position.
• Is there anyone you’d like to thank?

I absolutely love it! I wonder how much it weighs now, I’m sure it had a nice weight savings.
I never cared for trials. It just seems ridiculous. But I would love to have this bike geared as dual purpose bike.
I had owned 2 1974 Yamaha TY250 Trials bikes…buying both new. 1 in 1974 and then another (as a “left-over”) in 1976. Had a blast on them. Never competed in any real trials events…but did find myself doing some crazy things with them.
This one is cool…but more so a “pseudo-trials” machine (IMO) than one that would be really competitive in todays’ trials-world. Of course the skill-level of the rider could certainly make a difference. Cool build…none the less!
Moto Guzzi beat RE with a rear swingarm, 1928.
The color play on this bike is incredible. I’m not use to seeing that bluish aluminum finish alongside army green. That with the brass-y components. Really nice job.
