Bajaj Pulsar NS125: Common Problems, Fixes & Ownership Guide (2026)

Overview

The Bajaj Pulsar NS125 sits at the affordable end of the Pulsar lineup at Tk 1,73,850, targeting first-time buyers and students who want the NS visual identity without the NS160's price tag. It uses a 124.45cc fuel-injected, oil-cooled engine with CBS (Combined Braking System) — a reasonable safety feature for a 125cc entry-level bike.

In Bangladesh, the NS125 competes with the Yamaha FZS V3 FI and TVS Apache for budget-conscious buyers who want sporty looks. The FI system gives it a reliability edge over carburetted competitors and makes it easier to start on cold, humid Dhaka mornings.

Bajaj markets the NS125 through Uttara Motors with the same dealer network as the larger Pulsars, so parts availability is generally good. The bike is recommended for riders who want a manageable seat height and light kerb weight.

Common problems & fixes

• Stiff suspension on rough roads: Multiple reviewers note that the NS125's suspension is tuned on the firm side — acceptable on smooth tarmac but punishing on broken roads and speed bumps, which are everywhere in Bangladesh. There is no quick fix short of aftermarket fork springs; riding at slightly lower tyre pressure (26 PSI instead of 30) softens the feel marginally.
• Rear drum brake lacks bite: The single-channel CBS helps modulate braking, but the rear drum brake itself provides limited stopping power. Adjust the drum cable to reduce free play every 3,000 km and replace brake shoes at around 15,000–18,000 km.
• Switchgear feels cheap: The handlebar controls — indicators, horn, lights — have a hollow, plasticky feel inconsistent with the price point. These rarely fail outright but feel fragile. Avoid rough handling and keep moisture out of the switch housings.
• Fuel-tank rust in storage: Like all Bajaj models, leaving the tank near-empty during the dry season invites rust. Keep it topped up or add a fuel stabiliser if storing for more than two weeks.
• Outdated instrument cluster: No Bluetooth, no gear position indicator, basic backlit console. This is a design limitation, not a failure — but worth knowing if you compare against the Yamaha FZS V3's modern dash.

Maintenance & service tips (Bangladesh)

• Oil change every 3,000 km with 10W-40 semi-synthetic. The NS125's engine is small enough that skipping an oil change has more immediate consequences than on a larger-displacement bike.
• CBS adjustment: The CBS linkage between front and rear brakes can go out of calibration if the rear drum is adjusted without also checking the front. Have an authorised Bajaj technician set the CBS balance every 8,000 km.
• Chain: Lube every 500 km; during monsoon, every 300 km. The smaller engine means chain loads are lower, but rust is still a risk in Bangladesh's humidity.
• Air filter: Clean every 5,000 km. The NS125 air box is easy to access — learn to clean it yourself to save time and money.
• Spark plug: Replace every 15,000 km. An NGK or Bosch plug is a worthy upgrade over the OEM unit if you want more consistent cold starts.
• Tyre condition: The stock tyres are adequate for dry conditions but lose confidence on wet surfaces. An upgrade at first replacement noticeably improves wet-weather grip.

Is it worth buying in Bangladesh?

The NS125 makes the most sense as a first bike for a student or young professional who wants the NS visual identity and FI reliability without committing to a Tk 2.6 lakh NS160. The CBS braking system is a genuine safety benefit for inexperienced riders, and the light weight makes the bike easy to manage in Dhaka's tight lanes.

The limitations — firm suspension, weak rear brake, basic instrument cluster — are real but expected at this price point. Most of the issues logged online are comparisons to pricier bikes rather than genuine failures.

Resale value is decent but not exceptional: the 125cc segment is competitive and buyers at resale time often stretch to a 150–160cc bike. Expect 65–70% of purchase price after two years.

Verdict: A practical first-bike choice for Bangladesh's city riders. If budget allows, the NS160 Fi ABS at Tk 2,62,500 is a meaningfully better bike — but if the NS125 is the ceiling, it is a safe and sensible option.
