TVS Jupiter review, test ride

    TVS has just added the Jupiter to its fleet of popular scooters. Has the south Indian two-wheeler manufacturer hit the bulls-eye again?

    The TVS Jupiter houses a 109.7cc, four-stroke, single-cylinder and air-cooled engine, as also used by the Wego, albeit in a new state of tune now. The Jupiter engine comes with re-mapped ignition, and a higher compression ratio that allows quicker warm-up and cold starting. Then there’s also improved combustion thanks to revised ignition timing, as well as a relatively slippery, friction cutting piston for improved wear character during cold starts.

    Bore and stroke measure 53.5mm x 48.8mm, while the Jupiter is fuelled via a carburettor and breathes via a viscous paper type air-filter. The Jupiter generates 8bhp at 7500rpm, with a peak torque figure of 0.81kgm at 5500rpm. The Jupiter engine is tuned for commuting, and power delivery feels strongest in the mid-range of its powerband. Throttle response and low end grunt are adequate for a scooter.

    The Jupiter’s vibe free engine is allied to a variomatic drive transmission system that worked seamlessly throughout our ride. During performance testing, the Jupiter proved adequate for its class, although it lags a slender margin behind the refinement and smoothness available on the Honda Activa. The Jupiter breaches 60kph from standstill in 9.9 seconds which pegs it at par with the Wego, and the segment leading Activa. The Jupiter steams on to achieve a true top speed of 86kph when stretched to the limit.
