The Comp 250cc features an Atomik 250cc powerful overhead cam engine, giving distinct performance advantages over standard old technology push-rod engine designs. Overhead cam (OHC) valve-train configurations place the engine camshaft within the cylinder heads, above the combustion chambers and drive the valves in a more direct manner compared to pushrods. Atomik have also put in a performance camshaft into this engine, producing faster revs, and improved low-range power. This engine also has incorporated a start-in-any-gear feature allowing you to quickly get back into the race, if you stall it.
Hi-tensile 4130-chromoly tube, a steel alloy containing Chromium and Molybdenum, has been used in the frame, giving a tensile strength of 97,000 lbs per square inch, stronger and lighter than standard steel frames. Attached to the frame, is a CNC machined removable sub-frame. The lightness of the frame design make this dirt bike very maneuverable on the track or trail, whilst retaining the strength to tackle the biggest jumps on any freestyle motocross (FMX) track.
A closer look of the Comp 250cc, you’ll notice its loaded with high quality precision CNC machined billet aluminum components, which are lighter and stronger than any other alloy, such as steel, cast alloy, or rolled aluminum. The CNC billet hubs lighten the bike, and are superior in strength to any other hub made of any other material.
The reliable and durable, 850mm long travel USD forks don’t bottom out on the big jumps, and are solidly attached to frame by a set of billet machined CNC clamps and triple tree. Holding up the rear suspension, is a heavy-duty Atomik 1200lbs shock with reservoir. Both front fork suspension and rear shock on the Comp 250cc is fully adjustable in rebound, compression and pre-load settings, to suit the riders weight, riding terrain conditions, and hardness and softness preferences. The rear shock is also protected from tyre flick-up of mud, dirt and rocks by an innovative durable plastic guard, to ensure continued maximum shock effectiveness whilst riding. The Comp 250cc features a CNC billet linkage system, linking the shock to the full alloy swing-arm, which increases the rear end travel and further reduces any chance of bottoming out on the rear.
The Comp 250cc sports a neat set of 7075 alloy rims, 21” on the front and 18” on the rears, a stronger alloy than 6061 type alloys. The 7075 T6 alloys are heavily utilized by the aircraft and ordnance industries because of its superior strength. The 7075 alloy in the rim has also been T6 heat-treated, ensuring maximum tensile strength. It also comes with durable Kenda tyres, designed for sand and mud conditions and feature aggressive tall knob patterns for deeper terrain bite with sufficient knob spacing for self-cleaning. The 21” fronts and 18”inch rear Kendas also feature improved casing structure for sidewall stability at low pressures.
An aftermarket standard stainless muffler on a 38mm race pipe increases power to 21HP and engine attitude is adjusted at the flick of a wrist of the ¼ turn Joker throttle, immediately flowing fuel through the 30mm Dekni carby.
A lethal combination of the highest quality materials, latest technological design and manufacture methods, have made the Atomik Comp 250cc, a preferred choice for Motocross, FMX and Supercross riders.
