About the Yamaha SZ

Overview

The Yamaha SZ is a commuter motorcycle from Yamaha. It has been discontinued. Mechiee still services it at your doorstep. Commuter bikes are built for everyday riding: economical, easy to handle and inexpensive to run and maintain. With a 153 cc engine it sits in the 150–250 cc class.

Engine and performance

Power comes from a 153 cc single-cylinder air-cooled engine that makes 11.9 bhp at 7,500 rpm and 12.8 Nm of torque at 6,000 rpm. Divide power by kerb weight and it has about 90 PS per tonne; by that measure, there is enough go for confident city riding and relaxed highway cruising. It has electric start.

Gearbox

It has a 5-speed manual gearbox, and a chain carries drive to the rear wheel.

Chassis, brakes and tyres

It is built around a diamond frame. Suspension is by telescopic fork at the front and swingarm at the rear. Braking is by a disc at the front and a drum at the rear. It rides on 17-inch alloy wheels with tubeless tyres — 2.75-17 at the front and 100/90-17 at the rear.

Size, comfort and range

The seat is 800 mm off the ground, which is about average and suits most riders. It weighs 134 kg ready to ride. Ground clearance is 165 mm — enough for most speed breakers. It is 2,050 mm long, with 1,320 mm between the axles. It carries 14 l of fuel.

Owning the Yamaha SZ

  • Mechiee doorstep service

    ₹1,249

    Mechiee's fixed doorstep service price for this model.

Maintaining the Yamaha SZ

  • Routine servicing

    Follow the schedule in the owner's manual for your exact variant and year. A regular service is the cheapest way to catch small problems before they become expensive ones.

  • Engine oil & filter

    Engine oil is the single most important consumable to keep fresh. Top up between services if the level drops, and change it on schedule.

  • Brake inspection

    With Disc and Drum brakes, check pad or shoe wear, lever and pedal free play, and braking feel at every service.

  • Chain cleaning & lubrication

    A clean, correctly tensioned and lubricated chain lasts longer and wastes less power. Check slack regularly, especially after riding in rain or dust.

  • Air filter & spark plug

    A clogged air filter or worn spark plug shows up as hard starting, weak throttle response and poorer fuel economy. Both are checked at a regular service and replaced when worn.

  • Disc brake fluid

    Brake fluid absorbs moisture over time, which lowers its boiling point. Have its level and condition checked and change it on the interval in the owner's manual.

  • Tyre inspection

    This bike runs 2.75-17 / 100/90-17 tyres. Check pressure, tread depth and sidewalls, and replace tyres that are worn or cracked.

  • Battery & electricals

    The battery is listed as 12V,5.0AH(10H). Weak starting, dim lights or a flickering console are early signs the battery or charging system needs a look.

Yamaha SZ specs explained

What the technical terms on this page mean.

Air cooling
The engine is cooled by air flowing over its fins. It is simpler and needs no coolant, which keeps upkeep straightforward.
Tubeless tyres
Tyres with no inner tube. A small puncture usually loses air slowly, which makes roadside repair easier.
Kerb weight
The weight of the bike ready to ride, with its fluids and fuel, but without a rider or luggage.
Bore x stroke
The cylinder's width and the piston's travel. A larger bore relative to stroke tends to favour revs; a longer stroke tends to favour low-speed pull.
Compression ratio
How much the fuel-air mixture is squeezed before it is ignited. It is one of the factors behind an engine's efficiency and power.
