Product details

The heart of the IMR Corse 140cc Pitbike: a 4-stroke single-cylinder built for performance

The IMR Corse 140 RR 140cc Pitbike is built around a 140cc 4-stroke single-cylinder engine, air and oil-cooled for optimal thermal management even during intensive use. Developing 14 hp (10.30 kW), this engine offers strong acceleration and a usable torque curve, ideal for exiting corners or clearing doubles. Lubrication requires 750 ml of oil, a standard volume that ensures the longevity of the internal components. This powertrain is housed in a black "Coupe" type tubular steel chassis, paired with an aluminum cantilever swingarm: a rigid and lightweight architecture (69 kg) that ensures surgical steering precision, confirming the high-end positioning of this 140cc Pitbike. To further your understanding of the mechanics, our expert guide on 110-125 cc engine maintenance remains a valuable technical reference, applicable to modern 140cc engines.

Starting and transmission of the 140cc Pitbike: the 5-disc clutch for total control

At the controls of the 140cc Pitbike, the 4-speed manual gearbox transforms every gear shift into a deliberate action, thanks to a 5-disc clutch with exemplary progressivity. This configuration, rare in this segment, allows for millimetric dosing of power to the rear wheel, a major asset on technical terrain or on the starting grid. The absence of electronic superfluity enhances reliability and the direct feeling with the machine: the rider manages inertia, engine braking, and traction without filters. This ensures a pure connection, typical of racing machines, making this 140cc Pitbike both a tool for learning sporty riding and a high-performance leisure weapon.

High-performance braking on the IMR Corse 140cc Pitbike: axial calipers and racing discs

The 140cc Pitbike does not neglect deceleration, entrusted to a coherent and powerful racing system. At the front, a 2-piston axial caliper grips a 190 mm IMR Racing disc, providing immediate bite and proven thermal fatigue resistance. At the rear, a 180 mm IMR Racing disc ensures stability and trajectory control in curves. This assembly, sized for the lightweight 69 kg and the top speed of the 140cc, delivers a firm and progressive lever feel. Passive safety is thus ensured by identified components, easy to inspect and maintain, in accordance with the best motocross safety practices for teens and adults detailed on our blog.

Exhaust and sound of the 140cc Pitbike: a line optimized for 4-stroke

The exhaust of the IMR Corse 140 RR 140cc Pitbike is designed to extract the best from the 4-stroke single-cylinder: a fluid evacuation of burnt gases that supports the 14 hp at high RPM while preserving low-to-mid range torque. The sound, deep and muffled for a 4-stroke, indicates the quality of combustion without disturbing the track environment. Integrated into the black and red lines of the plastics, the silencer contributes to the "factory" aesthetic of the whole. It is the final detail that confirms the care given to the consistency of this 140cc Pitbike, delivered ready to ride (excluding tires and stand) for immediate sessions.

1. To what type of rider is this IMR Corse 140cc Pitbike aimed?

With a seat height of 78 cm, an empty weight of 69 kg, and 14 hp delivered by a 4-speed manual gearbox with a 5-disc clutch, this machine is suited for a teen/adult morphology. Its ergonomics (117 cm wheelbase) and "Copa" type tubular chassis offer a large-size pit bike frame, unsuitable for young children.

2. What are the engine specifications of this 140cc Pitbike?

It features a 140cc 4-stroke single-cylinder engine, air and oil-cooled, developing 14 hp (10.3 kW). The engine oil capacity is 750 ml. It is a reliable architecture, requiring no fuel mixing, designed for the track and sporty leisure.

3. How is the transmission managed on this model?

The gearbox is a foot-operated 4-speed manual, paired with a 5-disc multi-plate clutch. This type of clutch offers better progressivity and a longer lifespan than standard clutches, ideal for intensive use or learning gear shifting.

4. What level of chassis/cycle parts does the IMR Corse offer?

The "Copa" type tubular steel chassis is paired with an aluminum cantilever swingarm. The front fork is an inverted 660 mm (37 mm tubes, axial mount) and the rear shock is a 280 mm DNM with a decompression reservoir and adjustments. It is a rigid and adjustable base, competition-style.

5. Is the braking system up to the performance level?

Yes, the entire system is by IMR Racing: at the front, a 2-piston axial caliper grips a 190 mm disc; at the rear, a 180 mm disc. This sizing ensures powerful bite and good endurance during long sessions, consistent with the engine's 14 hp.

6. Which wheels and tires are factory-fitted?

The rims are alloy, measuring 12 inches (front 100/90-12, rear 120/80-12). Crucial point: the description specifies that the bike does not include tires. You will need to order a set of 12-inch tires suited to your use (track, off-road, slick) separately.

7. Which accessories are missing to ride immediately upon receipt?

Besides the tires (see previous question), the stand (workshop stand) is not provided. Also, provide engine oil (750 ml, grade according to the manufacturer's manual) for startup, as well as your rider equipment (helmet, gloves, boots, protections), which are never part of the vehicle package.

8. What XtremRS warranty applies to this pit bike?

You benefit from the 2-year legal warranty, excluding consumables (tires, pads, oil, filters, chain kit, etc.) and rider safety equipment (helmet, gloves, protections). Claims are handled via our after-sales service upon presentation of the invoice.
