Honda XL750 Transalp vs KTM 390 Adventure R on track

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.
