Assen, Netherlands · 4.53 km · 2.82 mi · clockwise
TT Circuit Assen in Assen, Netherlands is modeled here as the Motorcycle GP Course: 4,532 m (2.82 mi) run clockwise through eighteen carded corners — twelve rights and six lefts — on ground that varies by less than 3 m across the whole lap. Every speed, distance and lap time on this page is a physics-simulation estimate from track geometry, not measured data. The reference line peaks at 183 km/h (113 mph) through the Hoge Heide kink at Turn 13 and bottoms at 53 km/h (33 mph) in the 18.5 m-radius Strubben at Turn 5. The model uses the fast line through Ruskenhoek rather than the chicane alternative. Simulated laps: 1:43.9 liter bike, 1:46.0 supersport 600, 1:50.1 middleweight twin.
Layout: Motorcycle GP Course — 4,532 m (2.82 mi) in the track model, 18 carded corners: 12 right, 6 left, run clockwise
Simulated lap estimates: 1:43.9 liter bike / 1:46.0 supersport 600 / 1:50.1 middleweight twin
Simulated average speed: 146.1–154.9 km/h (91–96 mph) depending on bike class
Slowest simulated point: Turn 5 (Strubben) at a 53 km/h (33 mph) minimum; tightest radius on the card at 18.5 m
Fastest simulated point: Turn 13 (Hoge Heide), 183 km/h (113 mph) in every class on the widest radius on the card, 230.9 m
Longest simulated brake zone: 165 m before Turn 1 (Haarbocht) on the liter bike (123 m on the 600, 84 m on the twin)
Total elevation gain per lap: 10 m (33 ft); no corner rises or falls more than 1.2 m (4 ft)
Longest corners on the card: Turn 11 (Duikersloot) and Turn 15 (Ramshoek) at 177 m each

Haarbocht is a 141 m right at a 63.3 m effective radius, nearly level at −0.5 m, at the end of the start/finish straight. It carries the longest braking zone on the lap: 123 m on the supersport 600, 165 m on the liter bike and 84 m on the middleweight twin, from a 131 km/h (82 mph) entry to a 98 km/h (61 mph) minimum shared by all three classes. The exit reads 138 km/h (86 mph) on the two larger bikes and 136 km/h (85 mph) on the twin, and it carries directly into the faster right at Madijk.

De Bult is a 156 m left at an 81.6 m effective radius, level to within 0.2 m. The simulation enters at 134 km/h (83 mph) with brake markers that spread widely by class — 90 m on the supersport 600, 114 m on the liter bike, 63 m on the twin, one of the longer zones on the lap — and settles at a 111 km/h (69 mph) minimum. The exit is 140 km/h (87 mph) on the two larger bikes and 138 km/h (86 mph) on the twin. The corner sits between two rights and the profile shows only a modest dip through it before the braking for Mandeveen.

Hoge Heide is carded as a 3 m right-hand kink with a 230.9 m effective radius, the widest on the card, and no elevation change. The simulation reaches it at 183 km/h (113 mph) in every class — the highest speed anywhere on the lap — and the minimum equals the entry; the exit is 181 km/h (113 mph). The brake markers attached here — 78 m on the 600, 114 m on the liter bike, 39 m on the twin — are the same figures the solver assigns to Ramshoek, which is where the deceleration actually happens.
