GPX Demon 150R Specifications

Design

The GPX Demon 150R is sculpted with an aggressive and modern look that’s characteristic of entry-level sports bikes. Its sharp fairings, edgy tank design, and split-seat configuration give it a racing DNA.

Built around a compact frame, the Demon 150R measures 1835 mm in length, 1050 mm in height, and 750 mm in width, with a wheelbase of 1230 mm. These dimensions, combined with a dry weight of just 130 kg, contribute to nimble handling and sporty proportions.

The bike rolls on 14-inch alloy wheels paired with wide tubeless tyres — 120/70 in the front and 140/70 in the rear — enhancing both stability and visual appeal. Available color options are expected to reflect the aggressive styling, though official shades are yet to be confirmed.

Engine

At the heart of the Demon 150R is a 149cc, air-cooled, single-cylinder engine with a 9.2:1 compression ratio, delivering 14.9 BHP at 8500 RPM and 14.5 NM of torque at 6500 RPM. This engine is mated to a 6-speed manual transmission with a wet multi-plate clutch, offering better control and gear flexibility compared to standard 5-speed rivals.

Fuel delivery is handled by fuel injection, ensuring better throttle response and efficiency. While the official top speed is around 100 km/h, the real-world performance is tuned more for daily commuting with sporty bursts rather than pure top-end racing.

Performance and Handling

Equipped with upside-down front suspension and a mono spring rear shock, the GPX Demon 150R offers a firm but balanced ride. The suspension setup allows for superior cornering performance and feedback on twisty roads, while maintaining comfort on urban terrain.

It handles well in city traffic due to its lightweight build and compact frame, but also maintains decent composure on highway stretches. Although not tailored for off-road use, it can handle slightly uneven surfaces thanks to its wide tyres and sturdy suspension geometry.

Ergonomics and Comfort

The Demon 150R is designed with a sporty riding posture, featuring a three-part handlebar and split seating. The seat height (not officially specified yet) seems moderately high, suiting medium to tall riders best.

While the bike leans toward a forward-leaning stance, it’s not as extreme as full-sized sport bikes, making it manageable for city rides and occasional longer trips. Pillion comfort is slightly compromised due to the sporty design but still usable for short distances.

Features and Technology

Despite its budget-friendly segment, the GPX Demon 150R is impressively loaded with features:

• Fully digital instrument cluster (speedometer, odometer, tripmeter, gear indicator, low battery/oil indicators)
• LED lighting system including headlight, taillight, and turn indicators
• Electric start
• Digital RPM meter and clock

These additions not only improve the riding experience but also give the bike a premium, high-tech feel uncommon in its class.

Additional Features

While it lacks high-end features like ABS or ride modes, the Demon 150R includes several convenience and safety touches:

• Engine kill switch
• Pass light
• Low battery and oil indicators
• Passenger grab rail

The absence of ABS may be a downside for some, but the dual disc setup does provide confident braking in most urban conditions.

Mileage & Fuel Efficiency

The GPX Demon 150R boasts an approximate mileage of 40 kmpl, which is respectable for a sporty 150cc bike with fuel injection. While not the most frugal in its class, it strikes a solid middle ground between performance and economy.

Its fuel tank capacity hasn’t been officially disclosed, but similar bikes in this segment usually feature 10–12L tanks, making it suitable for both daily use and weekend rides.
