Awesome!

Easy Installation, Easy to break in and comes with everything you need to freshen up that top end. Have about 6 hours on it in my 06 crf250 and its still going strong. Great performance and definitely know what my next piston will be too!

Would i have to get my cylinder serviced if i installed this 1 ring piston? Compared to the oem 3 ring design? Will the ring seat properly with the previous wear pattern?

A: There is no special servicing required for this piston versus a stock piston. Depending how much time is on the cylinder, it may be a good idea to run a quick hone through it to clean it up before installing this piston. That is very hard for me to determine though without seeing the current condition of the cylinder. Other than that though, again, no special requirements.

A: Any of the aftermarket pistons are going to be good. I would have no problem recommending any of the major manufacturers such as, Wiseco, JE, CP or Vertex. Each engine builder will have his own preference, but realistically they are all pretty similar. Personally i have always used Wiseco Pistons in my bikes.

Q: Compression Ratios and Hi comp option?
Over 3 years ago
Is this the correct compression ratio? The Vertex website offers a OEM replacement (13.2:1 for Honda CRF 250R 2010) and a high compression for 14.1:1. I'm not sure where the 13.6:1 comes from but it seems like a happy medium if its correct.

A: If you order this piston for a 2010 CRF250R you will receive a 13.2:1 compression piston.
