Yamaha XJ 900 S 1994-2004 - Standard Saute-Vent / Pare-Brise
Yamaha FZ6 N 2004-2006 - Touring Bulle - Pare-Brise / Saute-Vent

Interesting alternative for FZ6 N.
For me it is a must have for naked motorcycle. It does not matter in the city but has massive influence for comfort outside the town, especially on highways. It still won't make aerodynamics like in a sport motorcycle but it will be realese on longer trips through highway.

Superb replacement windscreen for California !!
Screen came after just few days, was solid secured. Installation was fast and not complicated, it seems to be carefully made and everything fitted ideal. Windscreen looks amazing, clarity and visibility is perfect. I think it's a cheapest and best choice to california. I heartily recommend it.
