3.51-mile motorcycle course. Kept separate from the 3.56-mile sports-car layout and the historical short motorcycle courses. Lap records include qualifying, races and practice where explicitly identified by MotoAmerica.

All-time bests by vehicle class

Up to ten fastest vehicles per class, across all documented years. Each vehicle appears with its best supported time on this layout. Qualifying, race records and record attempts retain their original context.

Selected published track and class records from NASCAR, IMSA and MotoAmerica, across the years documented by those sources. Official race-lap records and qualifying records are identified separately. Historical coverage is incomplete; a class may have fewer than ten known vehicle entries.

Coverage is incomplete: these are the best supported entries in our sources, not a certified worldwide top ten. A published race-lap record may be slower than a qualifying or test lap. “Not stated” means the vehicle’s model year is unconfirmed. Exact catalogue matches link to vehicle pages; other vehicles retain their sourced names. Unresolved specifications remain separate.
