is athena a good brand. and are the ATHENA 480CC big bore kits any good for the trx 450rs

 

I put the Athena 480 kit on my '04 450R two years ago. I also added a Stage II Hotcam and I had the head ported and polished and installed a full Yoshimura system.
I cut open the top of the airbox (HRC style)
I abosolutely love all the power gains!

Thank you. Is it still running well, any problems?

 

No problems at all. It runs great!
Still very reliable, just as much as stock.

 

thank you very much
