Mechanical Specifications for Quads

And Multiple Class Entry Rules

 

     Any deviations from these specifications may result in a disqualification of the racer/quad or such lesser penalty as NASQUAD Racing, LLC may impose.

 

                                                                             Young Adult Classes

 1.         Class YA450P - Young Adult 450cc Production Class – Ages 16-21.  Engine displacement to 450cc for four stroke engines and 350cc for two stroke engines.  All modifications permitted except engine hop ups.  Racing fuel permitted.  Any engine parts must be OEM.  No increases in stock engine displacement. No racing cams.  No high compression pistons.  No port tuning.  Etc.  If you have not touched the internals of your engine and you are 450cc/350cc or less, you can run in this class.  If, for example, you have a quad that was originally a 250cc two stroke and you have increased the engine displacement (even if the increase brings total displacement to 350cc or less) or have made any other engine modifications, you cannot run in this class.  All other modifications are permitted such as suspension, exhaust, air intake, clutches and sprockets, EFI controllers, re-jetting, lowering kits, widening kits, wheels and tires, re-gearing, nerfs, grab bars, bumpers, etc.

 

2.         Class YA450M - Young Adult 450cc Modified Class – Ages 16-21.  Engine displacement to 450cc for four stroke engines and 350cc for two stroke engines, with one exception described below.  All modifications are permitted.  Engine hop ups are permitted, so long as displacement does not exceed 450cc/350cc.  Racing fuel permitted.  High compression pistons, racing cams, etc., all permitted.  All other modifications are permitted, such as suspension, exhaust, air intake, EFI controllers, re-jetting, lowering kits, widening kits, wheels and tires, re-gearing, nerfs, grab bars, bumpers, etc.  EXCEPTION: Stock/OEM larger bore four stroke quads such as the Outlaw 500 and 525, KTM 525, Raptor 700, and Honda 700XX can run in this class, if their horsepower/torque rating is factory stock.  Any aftermarket modification that increases horsepower or torque beyond the factory stock quad disqualifies the quad from this class, and it can run only in the big bore open class.  As examples, if you have one of these big bore quads and you change even the air filter, or exhaust from OEM, you cannot run it in this class.  Additionally, you are limited to pump fuel in this class, while your 450cc competitors may use racing fuel.

 

 3.         Class YABBO - Young Adult Big Bore Open Class – Ages 16-21.  Engine displacement to 700cc for both four stroke and two stroke engines.  All modifications within displacement permitted.  Racing fuel permitted.

If, for example, you have a quad that was originally a 250cc two stroke and you have increased the engine displacement (even if the increase brings total displacement to 350cc or less) or have made any other engine modifications, you cannot run in this class.  All other modifications are permitted such as suspension, exhaust, air intake, clutches and sprockets, EFI controllers, re-jetting, lowering kits, widening kits, wheels and tires, re-gearing, nerfs, grab bars, bumpers, etc.

 

2.         Class A450M - Adult 450cc Modified Class – Engine displacement to 450cc for four stroke engines and 350cc for two stroke engines, with one exception described below.  All modifications are permitted.  Engine hop ups are permitted, so long as displacement does not exceed 450cc/350cc.  Racing fuel permitted.  High compression pistons, racing cams, etc., all permitted.  All other modifications are permitted, such as suspension, exhaust, air intake, EFI controllers, re-jetting, lowering kits, widening kits, wheels and tires, re-gearing, nerfs, grab bars, bumpers, etc. EXCEPTION: Stock/OEM larger bore quads such as the Outlaw 500 and 525, KTM 525, Raptor 700, and Honda 700XX can run in this class, if their horsepower/torque rating is factory stock.  Any aftermarket modification that increases horsepower or torque beyond the factory stock quad disqualifies the quad from this class, and it can run only in the big bore open class.  As examples, if you have one of these big bore quads and you change even the air filter, or exhaust from OEM, you cannot run it in this class.  Additionally, you are limited to pump fuel in this class, while your 450cc competitors may use racing fuel.

 Additional Restrictions

 

1.         The following additional restrictions apply to all amateur classes:

 

                        a)  No quad may be turbocharged or supercharged; all quads must be powered by an internal combustion engine that is normally aspirated or fuel injected; no rocket or turbine engines.

 

                        b)  No amateur quad may exceed sixty (60) inches in width, measured outside sidewall to outside sidewall.

 

                        c)  No quad may exceed fifty-six inches in wheelbase (center front wheel to center rear wheel.

 

                        d)  In classes in which racing fuel is not permitted, only pump gas of maximum 93 octane is permitted.  Fuel enhancers, power boosters, octane boosters, etc. are not permitted.  All racers in non-racing fuel classes must permit NASQUAD to take samples of their fuel or face disqualification.  Any racer in a non-racing fuel class who uses racing fuel or prohibited additives shall be disqualified and barred for life from future NASQUAD races.

 

                         e) Sound output from quads is limited to 105 decibels, measured in the same manner that the AMA measures.

  

2.         In the Pro class, the following additional restrictions apply:

 

                        a)  No quad may be turbocharged or supercharged; all quads must be powered by an internal combustion engine that is normally aspirated or fuel injected; no rocket or turbine engines.

 

                        b)  No pro class quad may exceed fifty-four (54) inches in width, measured outside sidewall to outside sidewall.

 

                        c)  No quad may exceed fifty-six inches in wheelbase (center front wheel to center rear wheel.

Multiple Class Entries

 

            Racers may run in multiple classes only as follows, upon the payment of the registration fee for each class, and subject to any time constraints:

 

            (YA = young adult, A = adult, 450 = 450cc, P = production, M = modified, O = Open, BB = big bore)

 

            1.         If a racer/quad qualifies for the YA450P class, he may also run in any other young adult class, and any adult class.

 

            2.         If a racer/quad qualifies for the YA450M class, he may also run in the YABBO, A450M and ABBO classes.

 

             3.         If a racer/quad qualifies for the YABBO class, he may also run in the ABBO class.

 

            4.         No adult racer (age 22 or higher) or old timer (age 45 or higher) may run in a young adult class.  No young adult or adult racer may race in the old timers’ class.

 

            5.         If a racer/quad qualifies for the A450P class, he may also run in any other adult class.

 

            6.         If a racer/quad qualifies for the A450M class, he may also run in the ABBO class.

 

            7.         Women racers may also run in the age appropriate and quad specification appropriate young adult, adult or old timer’s class, as outlined above.  By way of example, a 16-21 year old woman who races a quad that qualifies for the modified young adult 450 class, may not run in the young adult 450 production class but may run in the young adult 450 modified class and/or in the young adult big bore open class, and/or in the equivalent adult classes.  A 22 to 44 year old woman who races a quad that qualifies for the big bore open adult class may run only in the big bore no restrictions adult class.

 

            8.         Old Timers may also run in the quad specification appropriate adult classes and any less restricted adult classes as described above.
