Yamaha R15 V4

• The Yamaha R15 V4 stands as a compelling choice and benchmark within the 155-cc sports bike segment.
• The heart of the R15 V4 is powered by a 155 cc, liquid-cooled, single-cylinder engine with SOHC and four valves.
• The inclusion of Variable Valve Actuation (VVA) is a feature that stands out in the segment.
• The R15 V4 makes use of a Deltabox frame, which is recognised for its rigidity and balanced weight distribution.
• The R15 V4 includes safety features such as dual-channel ABS as standard, supported by disc brakes at both ends.
• Another interesting feature of the R15 V4 is its digital instrument console, which offers Bluetooth connectivity and displays various information like speed, trip details, gear position, fuel consumption, and more.
• The R15 V4’s full-LED lighting setup includes a bi-functional LED headlamp, twin LED DRLs, and an LED taillight.
  

• The Yamaha R15 V4 is powered by a 155 cc, liquid-cooled, single-cylinder, SOHC, 4-valve engine.
• This setup generates a power output of 18.4 PS at 10,000 rpm and a torque of 14.2 Nm at 7,500 rpm.
• The VVA (Variable Valve Actuation) allows the engine to power efficiently at higher revs.
• The engine is paired to a 6-speed manual transmission and features a quick shifter (for upshifts), a feature rarely seen in this segment.
• The assist and slipper clutch provides a smooth and enriching ride experience by reducing lever effort and minimising rear-wheel hop during aggressive downshifts.
• The R15 V4 is capable of reaching a top speed of 140 km/h, an impressive feat for its displacement and weight class.
• The engine’s character is complemented by a precise throttle response, thanks to fuel injection, and the overall mapping is tuned for both city traffic and open roads.
  

• The R15 V4 features upside-down (USD) front forks, which is a first for the Indian market.
• These 37 mm KYB USD forks are considerably smaller in diameter when compared to the R15 V4’s rivals and even the previous international versions of R15s.
• The front suspension offers a perfect balance between sporting through racetracks and everyday use.
• Coming to the rear, the R15 V4 features a linked type monoshock, which has been retained from its previous generation yet tuned on the softer side, as comfort is a priority.
• The Deltabox frame complements the suspension really well in this case.
• The braking system in the R15 V4 comprises a dual-disc setup, now with dual-channel ABS.
• The brakes offer adequate stopping power in most scenarios, although the initial bite might not be as sharp.
  

• The dimensions of the R15 V4 are tight and efficient to suit most riding conditions.
• The length of this motorcycle amounts to 1990 mm, making it suitable for city manoeuvrability.
• The 725 mm width is convenient for a motorcycle during congested traffic.
• The height of 1,135 mm and a seat height of 815 mm strike a good balance. Tall enough for an aggressive stance and accessible enough for riders of average height.
• The 170 mm ground clearance is suitable for Indian roads.
• The curb weight of 141 kg is considerably lighter than most rival sport bikes.
• To summarise, the Yamaha R15 V4’s dimensions and weight present a harmony between track-inspired aggression and everyday usability.
