Common questions

What is the price of a Pulsar NS160, 125 or 135 block piston kit?

Block kits on this page start at Rs. 2,690 and go up to Rs. 3,930. The price depends on the model and brand; the kits above show each one.

Does the NS160 BS6 use the same kit as the older NS160?

No. We list a separate kit for the NS160 from April 2020. Check your RC: if it says BS-VI, use the BS6 section.

Will a Pulsar 135 kit fit the Pulsar 125?

No. They are different engines, and Bajaj lists a different kit for each. Pick the section for your bike.

Which Pulsar 135 LS kit should I buy?

Bajaj's 2014 catalogue lists a newer kit from June 2010 and an earlier one with a coated piston. Match the year on your RC, or compare with your old block.

Is the Pulsar 125 BS6 kit the same as the Pulsar 150 kit?

No. Bajaj lists a different block kit for each. The Pulsar 150 kits are on the Pulsar 150 page.

Is a bore kit the same as a block piston kit?

Yes. Bore kit, block piston kit, cylinder kit and piston cylinder kit all mean the cylinder block with its piston, rings, pin and circlips.

Does the kit include the cylinder head?

No. The kit is the cylinder block with its piston set. The cylinder head is a separate part.
