I have the exact same chain sprocket kit that LDH is promoting. It is excellent in every regard. Keep the chain and rear sprocket clean and lubed, and you will be happy. I've heard elsewhere that the Vortex aluminum rears are not the best.
Yea you bastard! Spend some time that site was the first thing I found when I got the 919 it lead me here. Where I found even more great information. But still your site had a lot of helpful info. It's worth updating. Looking at some of your other sites info looks a little stale on them too.
The problem is not much changes.... When you have a bike that has essentially stayed the same since 2002 like the RC51 or the 919 once you know the ins & outs of it or the limitations there isn't much more to discuss. The 919 is the worst in that regard as it is very limited in what you can do with it in regards to performance enhancement. There is just not much to work with it is only going to go so fast or handle so well due to its inherent weaknesses and throwing money at it doesn't make any real difference to that.
Basically the real joy of the 919 is simply using it for what it is & then personalizing it to your liking with the simple add-ons
If the CB1000R makes it stateside though then there will be a whole new realm of performance upgrades for both engine & suspension to renew interest in the Honda lineup!
LDH is right on in the sense that a 919 is a bit of a claymore, sword that is. You can lighten it up a bit, make it as sharp as you want, but it will always be a claymore and can never be made into a rapier. But it sure is a great claymore !
