There was some talk this weekend regarding LW Sportsman and whether it's legal to run slicks. I copied the section from the rulebook on lrrsracing.com. For those of you that said they have to be DOTs...am I missing something here because I can't find it?? As I'm reading it, all Supersport classes and P-twins are the only classes that require DOT approved tires.
Copied from the rulebook:
SPORTSMAN - Sportsman machines are based upon production models, sold by manufacturers and their dealers in North America for street use. Proof of compliance rests with the competitor entering the motorcycle. Single cylinder machines are exempt from street use requirements. Single cylinder 2 stroke GP road race machines are not allowed in this class.
All machines must have unaltered VIN numbers.
1. All machines must meet the equipment standards of Section 5 and 7, as well as the following:
A. Frame, head(s), cylinders, and engine cases must be from the same production model motorcycle.
B. The frame must be as originally supplied by the manufacturer on the approved model. Strengthening gussets or tubes may be added. Only brackets or tubes not supporting suspension, engine, or drive line components may be removed. Swing arms may be modified or replaced and rear shocks may be replaced or relocated.
C. Reducing engine size of machines from stock displacement to meet Sportsman class displacement limits is not allowed.
D. Fairings that meet the requirements of Section 5 and 7 may be used.
E. Liquid cooling is not allowed unless original equipment on the model being used.
F. Original type of induction system must be retained. If a machine originally was sold with fuel injection, then it must remain fuel injected. If the machine originally came with carburetors, then it must use carburetors, however they need not be the original type or size.
2. Sportsman Class displacement limits are absolute and are set as follows:
LIGHTWEIGHT SPORTSMAN (Novice Amateur & Expert divisions)
Single cylinder, unlimited displacement, production frame
Single cylinder, up to 500cc, unlimited frame
Two stroke, liquid cooled, up to 410cc
Two stroke, air cooled, up to 550cc
Twin cylinder, air cooled, non-desmodromic valves up to 700cc
Twin cylinder, air cooled, desmodromic valves, up to 650cc
Twin cylinder, air cooled, 2 valve, push rod, up to 895cc
Twin cylinder, liquid cooled, up to 515cc
Four cylinder, air cooled, 2 valve, up to 625cc
Four cylinder, liquid cooled, up to 410cc
NOTE: Ducati/Bimota/BMW Supermono, Woods Rotax, Yamaha TZR, Honda NSR & Aprilia RS machines are excluded from this class.
