Key Technical Specifications of Yamaha R15M
The Yamaha R15M is powered by a high-performance 155cc liquid-cooled, 4-stroke engine, which is designed to deliver maximum power and torque for an exciting riding experience. This engine is one of the key factors behind the R15M’s reputation as a top contender in the 150cc segment. Let’s take a look at the specifications that make the Yamaha R15M a standout motorcycle.
Engine and Power Output
The Yamaha R15M is powered by a 155cc, single-cylinder, liquid-cooled engine with Yamaha’s unique Variable Valve Actuation (VVA) system. This system allows the intake valves to operate at different timings depending on engine speed, optimizing both low-end torque and high-end performance. This results in a smooth, responsive ride across a wide range of RPMs.
- Engine Type: Single-cylinder, 4-stroke, liquid-cooled
- Displacement: 155cc
- Maximum Power: 18.4 bhp @ 10,000 rpm
- Maximum Torque: 14.1 Nm @ 8,500 rpm
- Fuel System: Electronic Fuel Injection (EFI)
- Cooling: Liquid-cooled
With a peak power output of 18.4 bhp at 10,000 rpm and a torque rating of 14.1 Nm at 8,500 rpm, the R15M offers impressive performance for a 150cc bike. The engine’s performance is complemented by an Electronic Fuel Injection (EFI) system, which ensures smooth throttle response and efficient fuel consumption.
Transmission and Gearbox
The Yamaha R15M uses a 6-speed constant mesh gearbox, which ensures precise and smooth shifting during both relaxed and aggressive riding. This gearbox is perfectly suited to the bike’s high-revving engine and allows the rider to maintain optimal power delivery at all speeds.
- Transmission: 6-speed constant mesh
- Final Drive: Chain
The 6-speed gearbox allows for a more comfortable cruising experience at highway speeds while still enabling quick gear shifts in the city or during spirited riding sessions.
Suspension and Handling
One of the key factors behind the R15M’s excellent handling is its high-quality suspension system. The USD (Upside Down) front fork is a feature that sets the R15M apart from its predecessors and many competitors. The linked-type monocross rear suspension further complements the bike’s ability to handle both aggressive riding and smooth city commuting.
- Front Suspension: 37mm USD (Upside Down) Fork
- Rear Suspension: Linked-type monocross
- Wheelbase: 1,325 mm
- Ground Clearance: 170 mm
The 37mm USD fork provides greater stability, especially during high-speed cornering, and reduces front-end dive during braking. Meanwhile, the linked-type monocross rear suspension ensures a smooth and controlled ride, even on uneven or bumpy roads. These features, combined with the bike’s 170mm of ground clearance, offer excellent handling in various riding conditions.
Braking System
The Yamaha R15M comes with a disc brake at the front and rear, both providing powerful stopping performance when needed. Additionally, the bike is equipped with single-channel ABS (Anti-lock Braking System), ensuring that the rider has complete control even during hard braking situations.
- Front Brake: 282mm Disc with ABS
- Rear Brake: 220mm Disc with ABS
The ABS system enhances braking safety by preventing wheel lock-up, especially during emergency braking or when riding on slippery surfaces. This makes the R15M a safer option compared to bikes without ABS, particularly in urban environments or during unpredictable weather conditions.
Dimensions and Weight
The Yamaha R15M is designed to be lightweight and compact, providing excellent maneuverability, especially in traffic or tight corners. Its overall design is meant to offer an ideal balance between stability and agility.
- Length: 1,990 mm
- Width: 725 mm
- Height: 1,135 mm
- Wheelbase: 1,325 mm
- Kerb Weight: 142 kg
- Fuel Tank Capacity: 11 liters
The bike weighs only 142 kg, making it one of the lightest motorcycles in its segment. The 11-liter fuel tank ensures a decent range, making it suitable for long rides or daily commuting. The compact wheelbase of 1,325 mm contributes to the bike’s agility and ease of handling.
Tyres and Wheels
The Yamaha R15M is equipped with high-quality tyres that provide excellent grip, both on dry and wet roads. The front tyre is a 100/80-17 and the rear tyre is a 140/70-17, both designed to ensure maximum traction and stability at high speeds.
- Front Tyre: 100/80-17
- Rear Tyre: 140/70-17
These tyres are paired with lightweight 17-inch alloy wheels, contributing to the bike’s responsive handling and performance. Whether you’re riding on the highway or maneuvering through city streets, the tyres offer the grip needed for a safe and enjoyable ride.
Design and Features of Yamaha R15M
The Yamaha R15M stands out with its aggressive and aerodynamic design, making it look like a much larger bike than it is. The design is heavily inspired by Yamaha’s R1 series, with sharp lines, angular bodywork, and aerodynamic fairings.
Aerodynamics and Styling
The Yamaha R15M has an aerodynamic design with a sleek, full-fairing that reduces drag, making it more efficient at higher speeds. The sharp-edged headlamp and the MotoGP-inspired design give the bike a futuristic look while improving visibility for the rider.
- Headlamp: LED Projector
- Tail Lamp: LED
- Turn Indicators: LED
The LED Projector headlamp provides bright and energy-efficient lighting, while the LED tail lamp and turn indicators enhance visibility and safety. These features, combined with the bike’s aggressive stance, give it a modern and sporty look that is bound to turn heads.
Instrument Cluster
The R15M features a full-digital instrument cluster that provides essential riding information, including speed, tachometer, fuel level, trip meter, and more. The digital display is well-lit, ensuring visibility even in bright daylight.
- Display Type: Full-digital
- Features: Speedometer, Tachometer, Trip Meter, Fuel Gauge, Gear Position Indicator
The gear position indicator is a particularly helpful feature, allowing the rider to know which gear they are in, ensuring better control over the bike, especially when accelerating or braking.
Ergonomics and Comfort
While the Yamaha R15M is designed for performance, Yamaha has also made sure to provide a level of comfort for everyday commuting. The split-seat design ensures that both the rider and pillion have adequate comfort, while the low-slung handlebars and slightly rear-set foot pegs offer an aggressive yet comfortable riding posture.
- Seat Type: Split-seat
- Handlebars: Low-set for an aggressive posture
The ergonomic design allows the rider to experience a track-like riding posture, without sacrificing comfort during city rides.
