1998 Yamaha Banshee YFZ 350
Twin
This project
began as a way for me to get over my dirt bike boredom. I had been
riding motorcross bikes all my life and started to get bored with
them. I decided to give quads a try as I'd always wanted one but
never could afford it. I sold my KTM 250SX and bought this 1998
Banshee in March 2005. When I got it, the only mods where some
worn out RAZR tires and a proflow filter setup. On the way home from
picking it up, I said I would ride it for a year before I started modding
it. 3 weeks later I had a ton of items for it I'd purchased on eBay
and Project Banshee was
officially underway...
Here is all the
information from when I purchased the quad to it's current state.
