This is where it all began. Over 40 years ago, the sandy, gritty soil of The Netherlands – and the resulting engine failures – proved that single-foam and paper filters gave riders air flow, but failed at protection. Twin Air’s breakthrough, fused-dual-layer design (now widely copied) combined performance and protection. The fused layers of open-pore foam and fine inner foam trap even the smallest particles. The new, rounder design boosts airflow. So do the minimized seams made possible by a revolutionary micro-gluing process: Shorter seams = more foam = more flow.
I rarely leave a review but this one was real bad. This piston didn’t have the screwdriver groove in it to help install the wrist pin clips. Beta uses one sided wrist pin clips—there’s no special tool. A groove for a screwdriver should be on there and is in the picture of the product. We messed with it for over 2 hours and ended up putting the old piston back in with new rings after cleaning it up real nice. We never even got one clip in and scratched up the piston in the process. Maybe they sent the wrong piston?? Don’t buy.
I bought a brand new battery from the dealer and this thing last me not even one season I went to start up the bike and this thing is dead. I can’t even charge it with special charger for lithium batteries, garbage sorry to say I won’t buy it again.
Great quality, but doesn't match 2024 Beta 300rr plastics
I purchased these thinking they would match the Beta red and unfortunately, they do not match the plastics of the 2024 model. Great quality and a trusted brand, I ended up buying them in black.
