Motorcycle Year Breakdown and Class Description



    • Maximum of 8” front fork travel and 5” rear wheel travel. There were a lot of bikes in 73-74 that had 5+ inches in the rear and 7.5+ inches out of the box. I will allow some bikes with small changes to be legal for vintage. Anyone not sure, we have a team of experts to help solve any issues. Box stock Honda CR 125's up to 78 are allowed in Vintage along with the Bultaco 135 & 136 and any “like design” MOTORCYCLE falling under the suspension rules. ALL PARTS AND MODIFICATIONS ARE SUBJECT TO APPROVAL!

  • EVO 1: 1975 - 1977 (with a few minor exceptions)

    • First real production line suspension improvements. Most of these bikes had 9 inches of front fork travel and were the real beginning of the long travel era.

  • EVO 2: 1978 - 1981

    • The true end of the twin shock era as we knew it! This class will be AIRCOOLED - DRUM BRAKES - NO LINKAGE! YES ALL NON LINKAGE MONOSHOCK YAMS ALLOWED. Exception is the Rokon (disc brake)

    • There were 81 125cc bikes that were liquid cooled AND LINKAGED (Suzuki) - THEY WILL BE IN EVO 3!

  • EVO 3: 1982- (See criteria!)

    • Any Production class bike with DRUM REAR brakes. Linkage, Liquid cooling, front disc brakes IS allowed.

    • This class has been the focal point for years and has been quite confusing as some bikes came with dual disc in 86 (Kawasaki) while Honda, Suzuki & Yamaha followed in 87. These bikes will join the EVO 4 Class.

  • EVO 4: Up to 1989 (See Criteria!)

    • Any production class bike with dual disc brakes, liquid cooling, linkage rear suspension.

    • These bikes transformed on a regular basis getting better and better throughout the years. Say what you want, but these are pretty well equal on today’s Vintage/Evo courses. I will be watching this class to see if it needs further adjustments. All depends on what shows up! PERIOD PARTS REQUIRED!

  • EVO 5: 1990 to 2000

    • These bikes were alike throughout the span with very little to no changes that were substantial.

    • We will trim and adjust as needed to make this class work. 2015 is the first year for this class so we'll see how it goes.

  • MODERN SUPPORT: 2001 to Current

    • This class will incorporate all years after 2000. Many may not consider the older bikes in this class to be modern but we are a vintage series and are more focused on that. We welcome all riders and bikes.
