Frequently Asked Questions

Will this piston fit my 883 Sportster as-is?

Only if your cylinders have been bored .010 in oversize. Stock 883 cylinders require the stock KB piston, not this oversized version.

Can I use this for a 883-to-1200 big-bore kit?

Yes — this piston is sized for 883-to-1200 displacement upgrades with .010 in overbore cylinders.

What compression ratio does this give?

10.0:1 compression, which requires fuel rated 87 octane or higher for safe operation.

Is this a single piston or a pair?

This is a single piston. Order the quantity you need based on your engine configuration.
