General Requirements: All Motorcycle Divisions

1. Vehicles in the Motorcycle divisions must be two wheeled motorcycles, with wheels in line, using one internal combustion engine, driving the rear wheel only.
    
2. Minimum wheelbase is 48 inches. Maximum Wheelbase is 72 inches.
    
3. Must have functional suspension with shock absorber(s) on front and back wheels. Limit straps and other suspension limiting devices are prohibited.
    
4. Must have brakes on front and rear wheels. Hydraulic disc brakes front and rear are highly recommended. Both wheels must have fenders. Removal of rear splash guard on sport bikes is allowed.
    
5. The following are prohibited: 3 wheeled vehicles. Choppers. Scooters. Mini-bikes. Streamliners. Enclosed front wheels.
    
6. Turn signals and mirrors must be taped or removed. Headlights and taillights must also be taped.
    
7. Motorcycles must be ridden solo. (Duh!)
    
8. All motorcycle riders must wear a full face helmet, leather suit, gloves, and boots. No exceptions. All helmets must be properly sized and fitted, full face with shatterproof visor, in good condition, and must have never been in an accident. Helmets must meet one or more of the following standards: Snell M2000, M2005, SA2000 or SA2005; ECE 22-05; BSI 6658A. Helmets rated DOT-only are not permitted.
    
9. Kill Switch: All motorcycles must be equipped with an engine kill switch with a lanyard (tether) attached to the rider, to kill the ignition in case of a fall-off. Proper operation must be demonstrated at Tech Inspection. Factory lean-angle kill switches are not an acceptable substitute.
    
10. Safety Wiring: Safety wired or pinned items must include: Front and rear axles, either the axle nuts or pinch bolts as appropriate; oil drain plug; clip-type chain master link (use of silicone OK); oil filter (not required but highly recommended).
     
11. Multiple chain master links on the same chain are not allowed.
     
12. Steering Damper: required for all motorcycles.
     
13. Controls: Hand levers must not be sharp or pointed. Throttle must be of a spring return type and snap closed when released. Handlebars must turn at least 20 degrees each way.
     
14. Breather hoses: Must dump into a catch can or into the air box. No fluids shall leak onto the track.
     
15. For liquid cooled bikes, it is recommended that all glycol based coolant be removed and replaced with plain distilled water only. Wetting agents such as Water Wetter or Purple Ice are the only recommended additives. (We are trying to avoid the problem of slick, oily glycol coolant ending up on the track. Please note that these additives provide no protection against freezing.)
