The TT Guard I found to be very good,no Vibe's at all, and it protect's just about all the engine.
The Black screen is a Yamaha touring screen,but it was not high enough for my liking so I cut down a old screen off a bmw 1200gs and bolted that to the top of the Yamaha screen.
I can now ride at motorway speeds with my helmet visor open with no wind in my eye's. It look's odd but it work's ...
If It help's I have just fitted a jack up kit to the rear shock , I bought it off ebay for 20 pounds.
This seems to be a cheap way of getting that bit extra ground clearance,with out having to get a high level exhaust which cost far to much for me
I have also fitted a set of Front fork spacers to make the front end harder.
I went out mid week to try the bike off road fully loaded with the kit I will be taking on my spring trip and It is works far better now off road with these Mods to the Forks and rear shock.
Maybe you can see in this photo the difference in ground clearance with the mods fitted.
