Frequently Asked Questions



What is SuperMoto?
     SuperMoto is a style of motorcycle riding which uses smooth tires on a course that includes both dirt and pavement sections.  Pavement sections may be permanent tracks, like a kart track, or may be configured on a parking lot somewhere.  Dirt sections are motocross inspired, but not as demanding as a full MX track.  Wikipedia definition of Supermoto.


Sound Limits
     North Star Raceway @ Strathmore Motorsport Park has a sound limit of 87dB for all users.  Many stock off-road pipes are quiet enough to meet this limit, such as those fitted by the factory on Yamaha WRs, Honda CRF-Xs, Kawasaki KLXs, and Suzuki RMXs.  Other means of helping to quiet down your motorcycle include header wrap, insulating the air box with foam, and installing power bomb headers.  
Some bikes that we already know will pass the sound limit requirements are:
   -   Yamaha WR250X with FMF Q4 exhaust.
   -   Yamaha YZ450F with stock WR450F exhaust.
   -   Suzuki RMZ450 with stock RMX450 exhaust.

     Riders need to recognize that "back yard" sound testing will never produce exactly the same results as a a sound test done in the test environment at the track.  Please make attempts to lower the sound level of your bike by as many dB as you can, but consider coming out for a sound test even if you measure your bike to be a bit louder than 87dB in your back yard or garage.  


How big of a Bike can I run on the Track?
     On our current track, the upper displacement limit is 550cc for twin cylinder bikes, and 690cc for single cylinder bikes.  250 to 450cc displacement bikes are the most common.  


Tires
     Though SuperMoto bikes traditionally use 17" rims with street tires or racing slicks, "Big Foot" bikes are more than welcome.  There are street bikes (Harley Davidson has some models) that use 18, 19 & 21” wheels, so used takeoffs from a local shop spooned onto your stock dirt-bike rims is a great, cheap way to come try out SuperMoto!


What do I need to add to my bike to ride on the track?
     Your bike should be equipped with footpeg sliders, axle sliders, and bar end sliders or bark busters to keep from gouging the track in the case of a crash.  


What are footpeg sliders?
     Footpeg sliders protect the track surface from being gouged by your footpegs, should your footpegs come into contact with the surface of the track.  
     Footpeg sliders may be purchased or manufactured by the rider and must be securely fastened to the footpeg.


Sliders for many models of motorcycles are available for purchase from many local shops, including GW Cycle World.


One method of manufacturing your own sliders is using hockey pucks.


Sliders should be attached to the pegs as solidly as possible.  Screws, from the top side of the peg into the slider tend to work well.  A layer of duct tape overtop of whatever attachment method you choose also will help to keep the slider in place.

Can I have Antifreeze in the cooling system of my bike?
     Yes.
However, you may NOT have ethylene glycol antifreeze in your bike.   In addition to plain water, propylene glycol coolants are acceptable.  
Examples of propylene glycol antifreeze include (but are not limited to):
- Amsoil Propylene Glycol Coolant
- Evans Waterless Coolant
- Engine Ice
