A street tracker with race-tuned Yamaha MT-07 power
Building a competitive flat track racer is downright scientific. Countless factors like weight, geometry, power delivery and gearing all have to be optimized to the nth degree. But building a street tracker is simpler; as long as you have the flat track look and feel locked in, whether or not it can actually hold its own on a dirt track is inconsequential.
Unless, of course, your name is Michael ‘Woolie’ Woolaway, and you’re the head wrench at Deus in Venice Beach, California.
Woolie’s idea of a street tracker is a race bike with lights?and that’s pretty much what he’s delivered here.
We’re not exaggerating. Nicknamed ‘The Framer,’ this Yamaha MT-07-powered machine was designed as a properly competitive AMA flat track mile racer, which could do double duty on the street too. So it’s a completely ground-up build.
Woolie started with the motor from a 2017 MT-07?a widely acclaimed power plant that’s similar to the one in Yamaha’s AFT MT-07 DT factory race bike. To get the 689 cc parallel twin up to race spec, he tore it down, then rebuilt it with a factory Yamaha racing kit.
The kit includes oversized pistons, a ported cylinder head, upgraded valves and cams, and a revised electronics package to enable custom engine tuning.
Every moving part inside the engine was sent to WPC for an advanced micro shot-peening anti-friction treatment, to improve both performance and longevity.
For the frame, Wooli...
