            A:

            Thank you for your question! Correct. The items can vary between a 4 stroke and 2 stroke bike but you would get the piston rings, circlips, pin, and piston. Please let us know if there is anything else we can assist you with.

            A:

            Thanks for your question! Top end bearings must be purchased seperately. They are not included with the piston and rings. In order to find out if this would raise the compression we would need to know the exact year of your Suzuki RM250. Please reply back by email or give us a call at 888-339-3888. We are more than happy to assist you.
