Pikes Peak 250
Don’t let the size fool you. There are motorcycles with bigger engines on Pikes Peak, but the Pikes Peak 250 class is fast and competitive. These machines are usually factory built for racing with two-stroke and four-stroke single or twin cylinder engines.  250cc Record: Jason Archuleta (2012), 11:41.015.

Pikes Peak 450
A popular class with many riders. Two-stroke and four-stroke engines are eligible.

Single and twin-cylinder engines are allowed.  Pikes Peak 450 Record: Travis Newbold (2012), 11:06.618.

Pikes Peak Heavyweight Supermoto

All eyes will be on these thundering machines.  Pikes Peak 1205 Record: Carlin Dunne (2012), 9:52.819.

Quad Modified
Essentially four-wheeled motorcycles, these machines are limited only by tread width and the use of an ATV engine of 500cc or less. Stability is aided by extreme weight-shifting by the rider. Cornering velocity is very high while the relative smallness of the engines hold down outright speed.  Quad Modified Record: Steve Tutt (2012), 11:40.521.
