M2R RACING RF140 Pit Bike Recently revised and improved, the series 2 RF140 pit bike has been built on the CRF110 style platform.
Reinforced Black SDG HubsReinforced Black SDG Hubs, have been laced with satin black spokes, anodised red spoke nipples and strong reinforced powder coated black steel rims. Super chunky block pattern knobbly motocross tyres offer awesome off-road grip. Not only is this wheel set up super strong, but looks freaking cool. Trick as hell. 
Hydraulic M2R RACING Front ForksThe trick anodized inverted hydraulic M2R RACING front forks work well, feel great and have plenty of travel keeping the front wheel planted where it’s needed. 
M2R RACING Adjustable Rear ShockThe M2R RACING rear shock is spring adjustable, works well, and offers great feedback to the rider. 
Extended Swing ArmThe chassis also features an extended swing arm which helps with stability at speed over whoops and ruts. 
Vented Brake DisksIf you’re going fast then you want to be able to stop sharpish. Fitted up front is the same twin pot hydraulic front brake as fitted to our factory works spec supermoto race bikes, including a huge 220mm heat dissipating vented wavy front disc. The rear brake, also hydraulic, is a single pot, again coupled up to a vented 190mm wavy disc. 
Gripper SeatA few other nice touches at no extra charge are… a gripper seat, copied from motocross, it helps the rider keep seated in one position, rather than slipping back and forth along the seat. 
Soft Rubber Red GripsSoft rubber red grips are colour coded with the CNC chain adjusters, rear chain guide, fuel line and breather pipe.
For hooning about on fields, through wooded trails, gravel pits and tracks, if you’re looking for a really decent bike, that’s got some ‘trick’, then this is it. And if you want to go further and motocross it, you can easily upgrade the suspension for the ultimate off-road experience. Buy it today and you could be riding it tomorrow. Features:

All of our Pit Bikes use inner tubes but a lot of our other vehicles are tubeless. As a rough guide, hub motors tend to be tubeless, and split rims tend to be tubed.
Generally, if you can see a 'car style' valve on your rim, your wheel is likely tubeless. If the valve has movement and looks like a push bike valve, it is likely tubed.
All our products come with a warranty. The warranty will vary dependent on the model. For specific information, click the "DESCRIPTION" tab and scroll to "Warranty" at the bottom of the page.
We strongly recommend using E5 "Super Grade" (97+ Octane) petrol only in our vehicles.
E5 has less Ethanol than E10, and although E10 is suitable for vehicles used regularly, it may cause maintenance issues in vehicles used infrequently.
At 10% Ethanol, the E10 fuel will age, degrade and split faster if left in the tank or carburettor or stored than E5 and is also more corrosive on vehicle parts.
If a vehicle is unused for an extended period, the most likely cause of not starting is the petrol. With the recent addition of Ethanol, petrol only has a 3-6 months shelf life, and you can expect approximately three weeks at summer temperatures in a vented fuel tank. After this time, the performance will suffer.
As petrol ages, it will change noticeably in colour, smell, and viscosity. Running your vehicle with aged fuel will cause hard starts, poor performance and gums may cause blocks in the carburettor and plug fouling.
We strongly recommend that you use or drain the fuel before storing your vehicle for an extended period.
Before looking for failing components or setup issues, replace the petrol in the tank, and if necessary, empty, check and clean the carb.
