MOTOCROSS TWINSHOCKS/EVOLUTION SERIES |
The Falcon Grasstrack and Longtrack suspension systems are based on the 32 mm bore Motocross shock absorbers. The dampers are gas assisted and are built with high tensile hard-chromed damper piston rods to help resist stone damage, and polyurethane seals, which are more wear and damage resistant than an ordinary rubber seals. |

SHOCKS FOR SPECIAL TWINSHOCK MOTOCROSS BIKES |
We are increasingly being asked to supply shock absorbers for special twinshock motocross bikes. These usually take the form of a monoshock bikes converted for twinshocks or non standard swinging arms being fitted to existing twinshock machines. TO ANY BIKE, THE FITTING OF NEW SHOCK ABSORBERS, THE ONUS IS ON THE BIKE OWNER TO ENSURE THAT THERE IS SUFFICIENT CLEARANCE AROUND THE SHOCK ABSORBERS OVER THE FULL TRAVEL OF THE REAR SUSPENSION. THERE SHOULD BE CLEARANCE BETWEEN THE FRAME, SWINGING ARM, AIR BOX, AND EXHAUST SYSTEMS. IT SHOULD BE NOTED THAT BIKES LIKE THE HONDA CR 250 RED ROCKET 1978/79 REQUIRE MODIFICATIONS TO THE TOP SHOCK MOUNTINGS TO CLEAR PIGGYBACK SHOCK BRACKET. FAILURE TO CHECK CLEARANCES WILL RESULT IN DAMAGE TO THE SHOCK ABSORBER. ANY DAMAGE CAUSED BY INSUFFICIENT CLEARANCE ON THE BIKE IS NOT COVERED BY OUR GUARANTEE. A good way of checking for clearance is to fit the shock absorbers without the springs and move the back wheel through it full travel. If in doubt please contact the factory |
