How the MotoQuant Physics Engine Works

A first-principles tour of the 15-sub-model RK4 physics engine. Engine torque curves, Pacejka tires, clutch slip dynamics, weight transfer — what we simulate, what we validate against, and what the residual error actually means.

Why 600cc Supersports Were Running 200ms Slow in Our Sim

MotoQuant's 600cc inline-four sims were biased +0.207s slow against Sport Rider and MotoStatz benchmarks. The fix was one number: max_engine_decel_rads2 lifted from 150 to 600 radians per second squared. Why a 600cc inline-four crankshaft physically wants to decelerate four times faster during clutch slip than the old cap allowed, what the GSX-R 600 K6 / R6 13S / CBR600RR 2013 sim ETs look like after the fix, and how K5/R1/Hayabusa reference baselines stayed pinned to four decimals through the change.

How a 2-Stroke Expansion Chamber Actually Works

A pressure wave at 500 m/s, a tuned-RPM peak about 1,500 rpm wide, and a +0.494 s simulator bias on the 2T cluster. Why the pipe IS the engine on an RX100, RD350, or RGV250 — and what that means for cost-per-tenth at an Indian drag strip.

The Physics of a Perfect Launch

Clutch engagement RPM, tire slip ratio, and weight transfer work together in the first 0.4 seconds. Getting any one wrong costs you tenths. Here is what the math says.

KTM Duke 390 Quarter Mile: From 13.3s Stock to an 11.342s Record

MotoQuant simulates the stock 2022 Duke 390 at 13.30s and 162 km/h trap at Aamby Valley. Fast Track Racing India ran 11.342s with the same engine. Two seconds of ET decomposed mod-by-mod, with Indian retail pricing — plus a practical ₹49k build that puts the bike under 12.6s.

Indian Drag Strips Ranked by Elevation: How Altitude Flips Quarter-Mile Order

MMRT at 78 m runs a stock Hayabusa Gen 1 at 10.262s — 0.21s quicker than the same bike at Aamby Valley (679 m), but 4.6 km/h slower at the trap. The order flips entirely for a 200cc commuter, where MMRT wins on every metric. MotoQuant sweeps the same physics across all five active Indian strips (MMRT, BIC, Kari, Hyderabad, Aamby Valley) and shows which bike class wants which venue. Drag-prepped turbo Hayabusas want Aamby. Stock R15 V4s want MMRT. The crossover sits between 80 and 120 hp.

Pulsar N125 vs Raider 125 vs Glamour 125: Which 125cc Commuter Is the Fastest?

MotoQuant sims the TVS Raider 125 at 20.63s, Pulsar P125 at 20.68s, Pulsar N125 at 20.70s, and Glamour 125 at 21.28s on a flat quarter mile. India's most-bought motorcycle class has zero published ET data because the segment buyer searches for fuel economy, not drag times. The Raider 125 wins by 0.07s on a sharper ignition map and 5 kg less mass; the Glamour 125 trails by 0.65s but saves ₹25,000/year in petrol. Cost-per-tenth ladder topped by a ₹450 13F sprocket (~0.20s) and a ₹2,100 sport-rubber rear (~0.18s) — the cheapest tenth in the entire MotoQuant catalog on any bike under 200cc.
