Common questions

What is the price of an R15 block piston kit?

R15 block kits here cost Rs. 3,600. Each version has its own kit above.

How do I know which R15 I have?

Check the year on your RC and the badge. 2008 to 2011 is the V1, 2011 to 2017 the V2 (the R15 S is a separate model), and from 2017 the V3 with a 155 cc engine. The V4 came in 2021.

Is the V1 kit the same as the V2 kit?

No. Yamaha's parts catalogue lists the same cylinder for the V1 and V2 but a newer piston for the V2, so each has its own kit.

Does the V3 kit fit the R15 V4?

No. Yamaha's parts catalogue lists a different cylinder for the V4.

Is there a kit for the R15 S?

Not yet. Yamaha's parts catalogue lists a different cylinder for the R15 S, so the V2 kit is not listed for it.

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 Yamaha kits?

No. They are DEXO kits, aftermarket and not Yamaha-branded.

Can I return it if it does not fit?

Yes, within 10 days of delivery.

Is cash on delivery available?

Yes, for most pincodes.
