Snetterton Circuit (300)
Snetterton, Norfolk, United Kingdom · 4.82 km · 3.00 mi · clockwise
Snetterton Circuit in Snetterton, Norfolk, United Kingdom, is modeled here as the 300 Circuit: 4,820 m (3.0 mi) of centerline run clockwise through twelve carded corners — five lefts and seven rights. Every speed, distance and lap time on this page is a physics-simulation estimate computed from track geometry, not measured data. The lap is nearly flat, climbing 15.1 m (50 ft) in total, so the speed profile is set by radius alone: the wide sweepers at Riches, Hamilton, Williams, the Bomb Hole and Coram hold simulated minimums above 124 km/h (77 mph), while the 12.2 m Wilson hairpin drops the reference line to 43 km/h (27 mph), the slowest point on the lap. Simulated laps run from 1:52.2 on the liter bike to 1:58.7 on the middleweight twin.

Wilson is the hairpin of the lap: a 96 m right at a 12.2 m effective radius, essentially flat. The reference line reaches the corner already down to 72 km/h (45 mph) after a brake zone of 123 m on the supersport 600, 135 m on the liter bike and 105 m on the twin, and bottoms at 43 km/h (27 mph) — the slowest point on the simulated lap, identical in all three classes because grip, not power, sets the limit here. The exit climbs to 120 km/h (74 mph) on the two larger bikes and 116 km/h (72 mph) on the twin heading toward Palmer.

Agostini is the second-tightest corner on the course: a 114 m left at a 22.8 m effective radius, flat in the model. Braking is heavy — 132 m on the supersport 600, 162 m on the liter bike and 99 m on the twin — bringing the reference line to an 89 km/h (55 mph) entry and a 59 km/h (36 mph) minimum, shared by all three classes. The exit reaches 123 km/h (76 mph) on the 600 and liter bike and 119 km/h (74 mph) on the twin, with the run to Hamilton letting each bike build toward the second high-speed section of the lap.

Brundle is a 75 m left at a 108.8 m effective radius, flat in the model. Although the corner itself is fast — a 128 km/h (80 mph) minimum in every class — the braking that precedes it is among the longest on the lap because it arrives at the end of the straight: 129 m on the supersport 600, 138 m on the liter bike and 93 m on the twin, down to a 141 km/h (88 mph) entry. The exit is 144 km/h (89 mph) on the larger bikes and 140 km/h (87 mph) on the twin, and it is followed immediately by the braking for Nelson.
