Thanks for your input Roy. I've edited my post, it's the compression not rebound nut for clarification. So it's highly likely that:
1/ Gixxer 05-08 fork will fit our bike
2/ Gixxer 12-16 rims may fit our bike
3/ Should get aftermarket rotors or used Gixxer set
4/ Should get lower triple clamp, the top was untouched
5/ The fork was straightened, the riding feeling is harsher than before. I'll need to disassemble it to check.
I considered myself lucky after all, if I was a bit slower or faster I may end up under that van, it was less than 2 meters away from me at the time.
In fact my front wheel crashed into the road pole before both me and the bike got down to the trench. That to explain the rim damage.
Looked like oil or some sort of substance on the road. Front wheel looks to be a write off, New one since its a one off model from Suzuki or see if a old standard GSXR front wheel will work but it won't match the rear. As for the fork tube cap I do not think that is sold separately through Suzuki. I would try ebay for a GSXR-1000 set of fork tubes from 05-08 I believe those were the same basic forks with different brake caliper mounts than the GSX comes with. As for the lower triple stop broke off I will bet you the triple is bent. They are very easy to bend. I would look for a new lower triple, top triple clamp as well. This is why your forks are binding when the axle nut is tightened. Also after market brake rotors while not cheap are typically cheaper than Suzuki. Again try ebay for some used ones off a GSXR as I bet they are the same. Again you'd need to verify the fitment. Also those forks will need to be checked for straightness too.
A lot of stuff off GSXR's will work and will be much cheaper and easier to find. Good luck as it could have been one of those armco barriers you slid into or worse up under that on coming truck.
