Engine and performance

The 334cc liquid-cooled engine makes 28.77 bhp and 29.62 Nm through a 6 Speed. With a kerb weight of 184 kg that is 156 bhp per tonne, 39th best power-to-weight of the 51 bikes in this class we have reviewed.

The torque and power figures are well balanced, so it neither needs to be revved hard nor feels lazy when you do.

Dimensions in practice

The 42 FJ weighs 184 kg with fluids, has an 790 mm seat, 178 mm of ground clearance, and rides on a 1440 mm wheelbase. That clearance is generous: speed breakers and broken roads will not trouble the underbody.

The fuel tank holds 12 litres, good for about 354 km between fills in real-world riding.

Tyres are 100/90-18 front and 140/70-17 rear, tubeless.

Features, and why each matters

Grouped by what they do for you. Underlined items link to a plain-English explainer.

Safety and braking

  • Dual-channel ABS

    Stops both wheels from locking under panic braking. The single biggest safety upgrade on a two-wheeler.

  • Front disc brake

    Sheds heat and works when wet. Worth the small premium over a drum on any commuter.

  • Rear disc brake

    Adds feel and fade resistance at the back; matters more on heavier or faster bikes.

  • Tubeless tyres

    A puncture deflates slowly instead of instantly, and roadside repair takes ten minutes.

  • Side-stand engine cut-off

    Engine will not run with the stand down, which prevents a common low-speed crash.

  • Hazard lamps

    All four indicators flash; useful in fog and when stopped on a highway shoulder.

Convenience

  • Engine kill switch

    Switch the engine off from the right bar without reaching for the key.

Chassis

  • Alloy wheels

    Lighter than spoked wheels and they allow tubeless tyres.

  • Slipper clutch

    Stops the rear wheel hopping on aggressive downshifts. Also makes the lever lighter.

Lighting

  • LED headlamp

    Brighter, whiter and lasts the life of the bike. Halogens on rivals look yellow by comparison.

  • LED daytime running lamp

    Makes you visible to cars in daylight, when most two-wheeler collisions happen.

  • LED tail lamp

    Lights up instantly, which gives the vehicle behind a fraction more warning.

Console and connectivity

  • Digital console

    Trip meters, real-time mileage and a gear indicator. The analogue dial is disappearing.

Equipment against 42, Meteor 350 and CB350

What it lacks: bluetooth connectivity, turn-by-turn navigation and usb charging port, which rivals at this price offer. None of these are deal-breakers, but they show where the money went.

It is offered in 6 colours: All Star Red Silver, All Star Aurora Green, All Stars Matte Black with Black Clad, All Stars Nebula Blue, All Star Matte Black with Red Clad and All Stars Chrome. Colour availability varies by variant and dealer stock.
