Common questions

What is the price of a CBZ Xtreme block piston kit?

CBZ Xtreme, Achiever and Hunk kits start at Rs. 2,850 and go up to Rs. 3,980. Karizma kits starts at Rs. 2,990. CBZ, Ambition and Impulse kits are priced in their own sections above.

Does the old CBZ use the CBZ Xtreme kit?

No. We list a separate kit for the first CBZ and the CBZ Star. The CBZ Xtreme shares its kits with the Achiever and Hunk.

Black or silver block for the CBZ Xtreme?

Both are listed. Pick the colour that matches your engine; each kit page shows its block.

Do the Karizma R and ZMR use the same kit as the first Karizma?

Our listings name the Karizma, Karizma R and Karizma ZMR for the same kits.

Will an Impulse kit fit the CBZ Xtreme?

We list a separate kit for the Impulse. Pick the section for your bike.

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.

Are these original Hero kits?

No. None of these kits is Hero-branded. DEXO, GOETZE and USHA kits are aftermarket, and the VIPAR kit is sold under the VIPAR name.
