Nitrous 250cc

Nitrous 250cc Enduro and MX bike with a seat height of only 890mm, the Nitrous 250cc can be comfortably ridden by all teenagers, and even smaller stature adults... giving the full benefits of the 250cc OHC engines raw power, and the ability to maintain complete control and manouverability for all riders of  all heights. The 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.

With the latest design Motocross inspired chassis we have already achieved 1st 2nd and 3rd placing in the Asian motocross series, now you too can share in our latest technology at your local club meeting or casual ride day, the new frame design makes this dirt bike very manoeuvrable on the track or trail, whilst retaining the strength to tackle the biggest jumps on any freestyle motocross (FMX) track.

Take a closer look of the Atomik Nitrous 250cc, you’ll notice its loaded with high quality precision forged aluminium components, which are lighter and stronger than any other alloy, such as steel, cast alloy, or rolled aluminium. The new alloy hubs lighten the bike, and are superior in strength to other hubs made of other materials.

The reliable and durable, long travel USD forks don’t bottom out on the big jumps, and are solidly attached to frame by a set of forged alloy clamps and triple tree. Holding up the rear suspension, is a heavy-duty Atomik 1200lbs shock with reservoir. Rear shock on the Nitrous 250cc is fully adjustable in rebound, compression and pre-load settings, to suit the rider’s 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 Atomik Nitrous 250cc sports a neat set of strengthened rims, 19” on the front and 16” on the rears, a stronger material than alloys. It also comes with durable Motocross high grip tyres, designed for sand and mud conditions that feature aggressive tall knob patterns for deeper terrain bite with sufficient knob spacing for self-cleaning. The 19” front and 16”inch rear Knobbys also feature improved casing structure for sidewall stability at low pressures. 

An aftermarket standard stainless muffler on a 38mm race pipe increases power up to 21HP and engine attitude is adjusted at the flick of a wrist of the  throttle, immediately flowing fuel through the 30mm MIKUNI carbie.

A lethal combination of the highest quality materials, latest technological design and manufacture methods, have made the Atomik Nitrous 250cc, a preferred choice for all serious  MX riders.
