High compression piston for 17 KTM 450

Getting a high comp piston, just after recommendations. The wiseco racer elite looks good at 14:1. I will be running ms109.

What do the flat track guys use? What do you recommend?

Thanks

I’d recommend a CP or JE over the Wiseco... I’ve ran a couple of the racer elite pistons and have found the valve pockets to not be cut quite deep enough for my liking... (even with a stock cam the piston to valve wasn’t enough).

I used to run the wiseco HC in my kawi 450. I got a CP HC piston. Its better designed for sure.

Wiseco is great but JE and CP are certainly a step higher than that.
