Project YSF250r is a go! A Baja built yz250 swapped blaster.

Don’t go rubber, doesn’t help. The biggest thing is make sure the engine is mounted at the head stay. Not having a head stay is where a ton of vibration comes from. Use machined aluminum bushings you will be glad you did. Also getting a good (but expensive) anti vibe stem and bar clamp really makes a difference. Good luck on build and hope this helps
I would’ve thought the head stay would get more vibes coming through? Thanks for the tip.
