Norsemen HAS PURCHASED TRANSPONDER SCORING SYSTEM

In a move designed to improve accuracy and race flow, the Norsemen Motorcycle Club has purchased MotoTally transponder scoring system to be utilized by the D23 points keepers at ALL D23 Hare Scrambles in 2010.

The California State Parks Off-Highway Motor Vehicle Recreation Division has been testing sound emissions of motorcycles and ATV's for about a year. This information can be used to help enthusiasts find a muffler for their OHV that will comply with sound emission's standards. Only tests with a reading of 101 dBA or less less are included. The list is by make, model and year of the OHV tested.

Select the manufacturer of your OHV to link to the list for that manufacturer

ATK CZ Kawasaki Thunder
BBR E-Ton KTM TM
Bombardier Gas Gas LEM VOR
BSA Honda Maico Yamaha
Bultaco Husaberg Polaris  
Cannondale Husqvarna Suzuki  

This list is not intended to be an endorsement of any product, nor does it guarantee compliance if installed on your off-highway vehicle.

Not all mufflers will work the same on all OHV's. Since results vary with modifications, along with vehicle care and maintenance, there is no guarantee these mufflers will work on your particular OHV.

**Remember, the noise limits are not just enforced during events, there are laws in place now for riding on both private and public lands. Check the laws at the State and County levels before you ride.
