Dual radiator water-cooling keeps the engine running optimally even under the most intense conditions and heat. Still riding a two-stroke? Upgrade to a four-stroke engine with real power that uses less fuel and lasts longer than a two-stroke. A Japanese manufactured 30 mm PZ30 carburetor ensures consistent and powerful fuel mixing. The pressure and splash lubrication system uses 15W-40 engine oil and keeps things simple and running smoothly. Matching the Honda CRF250R, the CDI ignition system provides reliable spark to the simple yet powerful single cylinder engine. The solid-state CDI ignition includes electronic advance and lighting coil, and can be easily upgraded for customizability.

The wide-ratio five-speed manual clutch provides a smooth ride with plenty of control over your bike. The transmission uses a standard 1-N-2-3-4-5 gear layout and features a manual clutch for added control. The wet multi-plate clutch features dura-coated clutch basket fingers for extra durability and lifetime. The "wet" immersion in lubricating fluid constantly cleans internal surfaces and results in smoother performance and longer clutch/transmission life. The multi-plate clutch design is similar to that used in F1 race cars. Power transfer to the rear wheel is done with chain drive with a final drive of 13:42 (front/rear sprocket)The X37 uses a Taiwanese-made KMC 520-108L (width-length) drive chain linkage that effortlessly transfers power to the rear wheel as you crank the responsive throttle. With this kind of power at your fingertips, you’ll be on top of that mountain faster than all your friends.

Built around a CNC-machined and welded lightweight steel alloy frame, the X37’s engine combines the perfect mix of power and weight. The frame is incredibly strong, but surprisingly light, built of a special steel alloy and painted with chip-resistant matte black finish. The engine cylinder angle, along with the frame and fuel tank design, have been optimized to centralize the center of mass as much possible, leading to better stability and handling.

Speaking of handling, the X37 excels in this category. With smooth front fork action on high quality headstem bearings, the X37 rides like a dream. This is made possible through precision manufactured front and rear shock absorbers, designed for off-roading. The front forks use a standard adjustable inverted and hydraulic dual shock system. The aluminum alloy 56 mm front shocks (versus Honda's 47 mm shocks) have a huge 160 mm of travel. The mammoth rear shock has 110 mm of travel and feature a massive 95 mm diameter steel coil with rebound and pre-load adjustability. The nitro-gas oil-damped shocks also feature adjustable coil travel and a huge gas reservoir with adjustable pressure nozzle.

The X37 is designed with full-size adult riders in mind. This truly is a large piece of machinery with power to match. The Yuanxing off-road tires (F: 80/100-21", R: 110/100-18") have a unique tread pattern perfect for dirt, rocks, mud, and sand, with huge grooves. The front measures 21” while the rear measures 18” – optimized for larger adults.

The details of this bike are beautiful as well. Do you hate kick starting dirt bikes? Me too, and I was thrilled to find the simple and elegant electric push-button ignition on the X37. Starting your bike has never been easier – and in case the conditions are too cold, a backup kick start is included as well. A 6.7L fuel tank provides extra hours of fun without refueling. The 28 mm exhaust header pipe and 42 mm exhaust pipe feed dual aluminum mufflers with dual silencers, pumping a little extra power into the already powerful engine while keeping the whine to a legal level. The CNC-machined swing arm measures 75 mm thickness in its rear section, ensuring stable and strong connection with the steel alloy frame and subframe.
