TrailMaster teamed up with JHL Offroad to build the LX250R Racing — a full-size race bike built around name-brand components. At its heart is a water-cooled 249.9cc Loncin YK250 balance-shaft engine making 40 horsepower, fed by a Bosch EFI system and backed by a constant-mesh two-stage 5-speed manual gearbox.
The component list is all recognizable hardware: fully adjustable KYB shocks front and rear, NISSIN disc brakes, DID rims and racing chain, CNC forged alloy triple clamps and linkage, 7-series aluminum handlebars with folding levers, and Kenda tires on a 21-inch front and 19-inch rear. It also gets a stainless steel exhaust, a waterproof wiring harness and a non-slip gripper seat.
With a 37.8-inch seat height, 11.8 inches of ground clearance and a 235 lb curb weight, the LX250R is a genuine full-size racer built for adult riders. Electric start only.
Please note: This is a competition/racing model. As a racing bike it is sold without a warranty. CA customers: this item is NOT CARB approved, but you may use it on your private land. Use high-octane fuel — NO ETHANOL.
