Well time to freshen up the 450. I picked up a Honda 450R over the winter and have been trailing it for awhile now. Found out that jumping from the quad to the trike and back was very difficult. Mainly because of the radically different ergonomics.
The biggest difference between the two was the seat height. The trike was alot lower and really felt awkward. I helped it some by adding a couple inchs of foam to the stock seat but that still wasnt close enough.
We decided that the whole subframe needed to raised to get the desired seat height. So I took it back up to Halls Performance for some more modification.
We figured to keep it Yamaha, we would add a YFZ aluminum subframe and matching seat/ fender combo. There were a couple other issues that I wanted to address as well. The radiators that we originally used were just inadequate for the big 450 engine. I also wanted to use full length radiator shrouds instead of cut down versions I ran last year.
So anyhow... here's some progress pics.
