Triumph Trident 660 vs Yamaha MT-03 on track

One standing-start lap of the Ref Ring, our 3.4 km circuit with no home-crowd corners. Every braking point, apex speed and straight is computed from the published specs, so the stopwatch has no favourites.

The working: every assumption in the simulation

This is a point-mass lap simulation from published specs, the same quasi-static method club-level lap-time tools use. It is an estimate for comparison, never a measured lap.

Rider: 75 kg, added to each bike's wet weight.
Drivetrain efficiency: 90 percent of claimed peak power.
Aero drag area by class, 0.32 (faired supersport) to 0.44 (adventure and enduro); air density 1.2 kg/m3, rolling resistance 0.015.
Peak cornering grip by class, 0.88 g (enduro knobbies) to 1.15 g (supersport rubber), adjusted mildly for load: lighter bikes work their tyres less.
Braking from the front brake spec: disc size and caliper type set the ceiling, grip has the final say.
Launch capped by the wheelie limit computed from wheelbase and seat height, and by tyre grip through the friction circle in every corner.

Race notes

The Triumph Trident 660 laps the Ref Ring in 1:46.55 on paper, 8.66 seconds quicker than the Yamaha MT-03 at 1:55.21. That gap is worth about 325 metres at the flag, and the biggest single chunk of it, 2.34 s, comes at Spec Sheet Straight.

Through the corners it is 0 apexes to 4 between the Trident 660 and the MT-03. Top speed goes 193 km/h to 159 km/h. A faster lap is not the same thing as the better buy, which is why the full comparison scores value, practicality and ownership too.
