About the Bajaj CT100

Overview

The Bajaj CT100 is a commuter motorcycle from Bajaj Auto. It has been discontinued (production ended around 2022). 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 102 cc engine it sits in the entry-level 100–110 cc commuter class.

Engine and performance

Power comes from a 102 cc single-cylinder air-cooled carburetted engine that makes 7.79 bhp at 7,500 rpm and 8.34 Nm of torque at 5,500 rpm. Its stroke is longer than its bore (47 mm x 58.8 mm), a long-stroke layout that generally favours low-down pulling power. Divide power by kerb weight and it has about 69 PS per tonne; by that measure, performance is modest — fine for city traffic and steady cruising, less so for quick highway overtakes. The claimed top speed is 90 km/h. It has kick start only.

Gearbox

It has a 4-speed manual gearbox, and a chain carries drive to the rear wheel. It uses a wet multi-plate clutch.

Chassis, brakes and tyres

It is built around a tubular single down tube with lower cradle frame. Suspension is by hydraulic telescopic, 125 mm travel forks at the front and Spring-in-Spring (SNS), 100 mm wheel travel at the rear. Braking is by a drum at the front and a drum at the rear, with a combined braking system (CBS). Using the rear brake lever also applies some front brake, which shortens stops for riders who lean on the rear brake. It rides on 17-inch alloy wheels — 2.75-17 at the front and 3.00-17 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 115 kg ready to ride, light enough to push around and park easily. Ground clearance is 170 mm — enough for most speed breakers. It is 1,975 mm long, with 1,235 mm between the axles. Its 10.5 L fuel tank and claimed mileage of 99.1 kmpl work out to roughly 1,041 km per tankful on paper; real-world range is usually lower.

Features and equipment

Equipment includes an analogue instrument console and a halogen headlamp. Safety equipment includes low fuel indicator.

Owning one

The manufacturer's warranty is 2 years or 24,000 km. For the Bajaj CT100, Mechiee offers a fixed ₹899 doorstep service.

Who it suits

It is best suited to daily commuting and riders who put running costs first. Its gentle performance makes it a forgiving choice for a first bike.

Care notes for this model

Its chain drive needs regular cleaning, lubrication and slack adjustment. Being carburetted, it benefits from an occasional carburettor clean, especially if it has stood unused.

Maintaining the Bajaj CT100

  • 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 Drum 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.

  • Tyre inspection

    This bike runs 2.75-17 / 3.00-17 tyres. Check pressure, tread depth and sidewalls, and replace tyres that are worn or cracked.

  • Battery & electricals

    The battery is listed as Low Maintenance Battery. Weak starting, dim lights or a flickering console are early signs the battery or charging system needs a look.

Bajaj CT100 specs explained

What the technical terms on this page mean.

ABS
Anti-lock braking system. It stops a wheel locking up during hard braking so the rider can keep steering. A single-channel system works on one wheel, usually the front; a dual-channel system works on both.
CBS
Combined braking system. Pressing the rear brake also applies part of the front brake, which helps the bike stop more evenly.
Air cooling
The engine is cooled by air flowing over its fins. It is simpler and needs no coolant, which keeps upkeep straightforward.
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.
