KYB fork swap
Well I bit the bullet and decided to upgrade the forks on my 06-300. Picked up a set of KGB SSS forks off of a 2009 yzf. Had them shipped to Les at LTR where he put in heavier springs and revalved them for my type of riding/racing. I also bought a set of triple clamps and axle. My plan is to use my Gasgas front wheel. So far things seem to be lining up.the yamaha axle is smaller so I will machine up a bushing to go between it and the bearings.The problem at the moment is the brake calliper,my GG calliper does not fit onto the yamaha forks.
Question:Can I use a different bracket on my calliper to fit the yamaha fork or will I have to buy the yamaha calliper assembly? Any help from people that have done this swap would be great. Dave GG 06-300 de,2k2,10oz fww,rb head,carb mods,fmf gnarly,pivot pegs,really tall seat,brp sub mounts,Scott's damper,flex bars,tubliss,mx31 rear,mx51 front,LTR tuned suspension= great bike |

Is your Yamaha axle 20mm? If so, the wheel bearings from the earlier 00, 01,02 etc. GG should fit the bill. Double check (google) the bearing specs. OD against yours but they should be the same. The bearings are very cheap at a bearing house.
On my brake caliper the lower hole lined up with the forks and the other one will get welded shut and relocated on the caliper holder. You also will need to fab a spacer to move the caliper assembly away from the fork. I shortened the right side Yamaha axle spacer a bit and built a new one for the brake side that was a tic longer. I could have used the Yamaha spacers but the wheel was off center by like .070 not really worth worrying about though. I also used my 00' axle seals. Good luck with the swap!

You have to use the Yamaha caliper bracket with the KYB forks.
The OEM GG caliper will then bolt right on. I found that I have a better lever feel with the YZ caliper. It also was way easier to bleed. |

Also note Yamaha lists different front brake pads for 2003-2006 than it does for 2007-2012, which makes me think they changed calipers. The gassers caliper accepts the same pads as the 2003-2006 Yamaha ones.

Fork swap
Thanks for the info. Will check out bearings from an earlier model.Will also try to find a yz calliper bracket. Looking forward to fork swap done,won't be ready for the race this weekend but getting close. I'll post pics once I figure this photobucket thing out.
Cheers, Dave |

Is this the same even with the smaller Yamaha caliper used on the 07'+ 250f & 08'+ 450f?

No can do. The Gas Gas rim has different spoke spacing. |
