lowering

I am running 10.8's at 129 with 1.9 60' times fully stock would dropping the forks in the tree be any better or worse than strappining and what are the pros and cons on each Thanks

Strapping has more of an effect than just sliding the forks up. The down side to strapping is that you are hoping that the strap never breaks. Go all out. Strap the front, and slide the forks up about 1 1/2 inches. Plus buy an adjustable lowering link for the rear. Don't forget your kickstand may become an issue when you start lowering.

I wouldn't just lower the front you will be effecting the stability. If you plan on lowering it lower both the front and the rear. Straping allows you to go back to stock height more quickly than droping the forks but also limits your suspension travel. Once you lower the bike more than an 1.5 inchs your gonna need to do something about the kickstand.

Strapping the front should give you 2-3 tenths on the big end. I would suggest strapping the front, raising the tubes and lowering the rear. If you don't want to spend the cash on the adjustable link you can try using this trick on the rear links to drop the rear 2 in (as opposed to 3in drop created by the adj. linkage). I did this on my 2001 R6 when I didn't have enough money to buy an adjustable linkage and it worked out well ( it may not work on the R1 or could cause probems so be warned. I am not liable for any injury that may be caused). Remove the triangular links connecting the stock dog bone/rear shock/swingarm and flip them upside down so that the extended edge of the triangles short side is oriented towards the ground and not the seat. Do this for both sides and it will drop the rear 1.5-2.0 inches. If you keep the front at the stock height the kickstand will still work. DTD
