The TrailMaster RMX250 is a full-size dual sport dirt bike from TrailMaster's JHL line, built as a step up from the T5 for riders who want more time on the trail. It runs the Haojue TSR230 engine, a 223cc air-cooled four-stroke with a built-in balance shaft that smooths out vibration, paired with a 5-speed manual gearbox, electric and kick start, and a top speed of about 68 mph. TrailMaster backs that engine with a 2-year / 15,000-mile engine warranty.
The chassis is built for rough ground: a cradle frame, inverted front forks, a linkage rear shock, forged aluminum triple clamps and a tapered aluminum handlebar. A 19-inch front and 17-inch rear wheel on alloy hubs, 260 mm and 238 mm disc brakes, and 10.24 inches of ground clearance let it roll over roots and rocks, while the 33.1-inch seat suits adult riders.
It comes with a full light package: LED headlight with lens, turn signals, mirrors and a license plate holder, plus a digital speedometer and hour meter. The bike carries an off-road VIN; depending on your state it may be possible to register it for road use after inspection, so check with your local DMV. Available in Red and Blue.
