I'm not a huge fan of that design. It doesn't look like it will incorporate the stock gauges well, and there doesn't seem to be provision for the vertical offset that the stock upper triple provides. The stock setup for the 350/400 has a decent drop from the steering stem nut to the fork tube clamps. The bullit unit does not have that drop, so you'll end up dropping the front of the bike if you install it. Our bikes are twitchy enough as it is. No need making them twitchier by lowering the front end.
There are some other builders out there with nice uppers. I have seen a few posted on this forum, including TTR400 who is a member here. Can anyone else remember any other triple tree fabricators who put out a decent product?
