The M2R RACING 2025 Model RS-R 140 Dirt Bike
We’re excited to introduce our latest off-road dirt bike, engineered to redefine fun, adventure, and elevate your off-roading experience.
Designed for those who live for the thrill of off-road riding and MX, this new model merges M2R Racing Parts with rugged durability, making it the perfect companion for conquering the most challenging terrains.
Whether you’re a seasoned rider or new to the off-road scene, this bike delivers unparalleled power, precision, and control.
Prepare to embrace the next level of off-road excitement, where every twist, turn, and jump brings you closer to the ultimate thrill.
Superior Cockpit and Controls
Starting with M2R Racing Fat Bars featuring a 4-inch rise, the riding position offers “full control” without compromise. The waterproof Start and Stop buttons closely resemble those found on Yamaha MX bikes and provide a premium feel. And for the throttle, the Nibbi quick action throttle is top-notch. However, the most striking feature might be the exquisitely crafted CNC clutch and brake levers, which are the best we’ve ever encountered. Not only are they fully adjustable for reach, but they also boast a bi-folding design, allowing movement both upwards and downwards. The quality of these levers is truly exceptional and needs to be experienced to be fully appreciated. Lastly, poly plastic hand guards have been installed. Sitting on this bike instantly gives you the sense that you’re on something special.
CNC Foot Pegs & CNC Gear Lever
CNC Foot Pegs & CNC Gear Lever
The high-quality components extend to the meticulously designed CNC folding gear lever. But have you ever seen foot pegs like these before? Newly added to the M2R Racing catalogue, these CNC-crafted foot pegs are top-of-the-line, featuring replaceable teeth. When you’re fully committed to off-road riding, these foot pegs will securely hold your MX boots in place, ensuring maximum grip and stability.
POWER BOMB Performance Exhaust
POWER BOMB Performance Exhaust
Another exciting addition to the M2R Racing catalogue are the new exhaust systems we’ve been developing. These exhausts are designed to sit closer to the frame, eliminating the need for a heat shield. The standout feature, however, is the inclusion of the “Power Bomb”. Positioned at a key point in the system, the Power Bomb enhances performance by increasing the flow through the expansion and contraction of exhaust sonics, resulting in nearly a 10% flow increase. The outer chamber of the Power Bomb allows the air to expand, cool, and then ramp back up at a higher velocity. Additionally, it acts as a “pre-muffler”, helping to reduce the bike’s sound output by providing more surface area for the exhaust gases to absorb sound.
Cast Frame
Cast Frame
Unlike most other pit and dirt bikes, the frame is cast rather than welded. Casting forms complete parts, while fusion welding bonds joints between parts. A cast frame offers greater strength with less flex, though it may have some cosmetic casting indentations. However, the benefits far outweigh the drawbacks, making this the ideal choice for a high-end machine where performance is the top priority.
Wheels, Tyres and Brake Upgrades
Wheels, Tyres and Brake Upgrades
When you compare these brake calipers to those on a standard pit bike, the difference is clear. These calipers are simply superior in both performance and feedback. Paired with 3mm vented discs, they provide all the stopping power you could need. The wheels feature super-strong satin black rims with stainless steel spokes, all laced to a satin black hub – another example of top-notch quality. The tyres are aggressively designed, offering exceptional grip for the most demanding riding conditions.
CNC Chain Guide & CNC Chain Adjusters
CNC Chain Guide & CNC Chain Adjusters
It’s the small details that really stand out. Take the M2R Racing CNC chain guide for example – typically a basic plastic component, but here it’s been upgraded to a high-quality CNC version. Then there are the M2R Racing CNC chain adjusters. Instead of being plain and unmarked, these adjusters feature 20 marker points, allowing for more precise chain alignment. The result is reduced chain drag, leading to less wear on both the chain and sprocket. Simply superb!
M2R Racing Gripper Seat

Those little strips of fabric across the top really help keep you planted. They don’t throw off your balance in the corners if you stay in the same spot. You can still move around, but it just requires a bit more effort.
Engine
Engine
M2R has partnered with YX Motorsports for the 140 model. They make the best Honda clone 140cc engine, which is known for its proven reliability and impressive power. To maintain a big bike premium feel, we’ve also included the ever-useful electric start.
Oil Cooler
Oil Cooler
Pit bike engines tend to lose power when they overheat, but we’ve addressed that by pairing this engine with a newly designed M2R Racing Oil Cooler. It keeps the engine cool, effectively preventing power loss due to overheating.
M2R Racing Adjustable Shock
M2R Racing Adjustable Shock
The M2R RS-R series is equipped with a premium upside-down shock absorber that features adjustable rebound and compression, allowing it to be tailored to each rider’s weight. Additionally, note the two extra shock mount fixing holes. By using different configurations of these 4 mounts, the seat height can be adjusted by approximately 1 inch.
Optional DMN Upgrade
Optional DNM Upgrade
For riders seeking the ultimate in performance, we’ve teamed up with Taiwanese suspension experts DNM to offer an upgrade: a fully adjustable upside-down shock with a piggyback reservoir. It’s not cheap, which is why we’ve made it an optional add-on, perfect for those serious about racing.
6 Litre Fuel Tank
6 Litre Fuel Tank
Typically, pit bikes in the CRF50, CRF70, and CRF110 styles come with a 3.5-litre fuel tank. But with the RS-R series, we’ve gone big – equipping it with a massive 6-litre tank. That means we’ve just doubled your range and riding time!
