Hi-Speed Infinity 150

Engine and gearbox

The Infinity uses the DG150D-B engine: a single-cylinder, 4-stroke, air-cooled unit with an inclined cylinder and a balance shaft. It displaces 149.5cc from a 62 × 49.5 mm bore and stroke, with a 9.2:1 compression ratio and a carburettor with CDI ignition. Hi-Speed quotes 8.5 kW (about 11.4 hp) at 8,000 rpm and 10.0 Nm at 7,500 rpm, with a top speed of 120 km/h. You get both electric and kick starting. Hi-Speed does not give the number of gears; PakWheels lists a 5-speed gearbox and a fuel average of about 35 km/l.

Size and practicality

It measures 1920 × 770 × 1080 mm with a 1290 mm wheelbase and a generous 160 mm of ground clearance, which helps over speed breakers. Curb weight is 120 kg and the fuel tank holds 15 litres, giving a long range between fill-ups. Tyres are 90/70-17 at the front and a wide 120/70-17 at the rear. Hi-Speed does not list seat height or suspension type.

Equipment

There is one version on the official website. Equipment highlights are front and rear disc brakes, electric plus kick starting and the wide rear tyre. The official page does not mention lighting type, instruments or tubeless tyres, so check these in the showroom.

Price and warranty

Hi-Speed does not publish prices or warranty terms. PakWheels lists the Infinity 150 at Rs 420,000. Older listings from other sites show Rs 415,000, and an AlfaMall store listing has shown Rs 460,000, so prices clearly vary by source and date; confirm with a dealer.

Before you buy

Because Hi-Speed does not publish seat height, suspension type or the gearbox on its website, a test ride is the best way to judge comfort and fit. Ask the dealer whether the tyres are tubeless, what lights and instruments are fitted, and what written warranty comes with the bike. In our view it is also sensible to check the price of common spare parts, such as brake pads and chains, at your local market, because parts support matters more over years of ownership than a small difference in purchase price.

Is it worth buying?

In our opinion, the Infinity makes most sense for riders who want a 150cc with more style and better brakes than the usual commuter, at a lower price than the big Japanese brands. Disc brakes at both ends, a big tank and 160 mm ground clearance are real strengths. The weak points are that Hi-Speed shares very little official detail, resale value is generally lower than for Suzuki or Honda, and the carburettor engine is fairly basic. If you plan to modify the bike, its large owner community is a bonus.
