Gixxer front end (with fork leg extensions and GP Suspension cartridges) because it's what we had laying around. Custom upper triple and steering stem (after much trial and error with OEM parts off of various bikes). Retains OEM steering lock, ignition location, and the '06 GSX-R600 blue front wheel is a perfect match to the Yamaha blue on the FZ-07. GSX-R wheel, brake calipers, master cylinder, lower triple clamp, and matte black fender sourced from eBay. Brake lines are Spiegler. Shock is Penske double-clicker. Right mirror sacrificed for upgraded master cylinder, so we'll stick with the one until Johnny Law tells us otherwise, then we'll be looking for a set of bar-end mirrors or something.
Handles brilliantly. Excellent stopping power, more manageable brake dive, very natural steering and cornering, great stability. A little less wheelie-prone due to geometry change, and taller overall. Harsher on square-edged hits, but what else would you expect? Worth it for the added performance. Feels pretty much like a sit-up supersport with riser bars.
