Conditions-lake,hardpack not sure on distance but we all ran the same distance,we were all pretty much topped out,other than the viper,that rode so nice that I held it forever-lol.99 sx 500 -100 on speedo,93 on gps,2004 ZR 900-mild clutching-speedo only goes to 100,it was way past that-99 on gps,2002 viper,stock,117 on speedo-104 on gps,2002 SRX 700,clutch specs from blue by you from last year and geared down 2 teeth-118 on speedo-111 on gps.-Harvey
 

All of those numbers are as I would expect except the ZR 900. Not that I am a fan of the ZR at all, but they usually top out quite a bit higher than that.
 
I've seen 103 on my 500's speedo, before I studded, with a agressive trail set up. Stock clutching would have gone faster :shock:

Sure is cool having real results, eh?
 
Yep,I really thought the ZR would kill my SRX,it got to speed very quickly,just didnt have the top end I expected.I really like the GPS though,it takes all the bull crap out of the equation.Everyone enjoyed doing it although some were disapointed,it gave them some real figures to go by.the yamahas seemed to be allmost all about 7 mph off,other than the viper which was 13mph off.The ZR speedo only goes to 100 so no telling how far he was off,we also had a skidoo mxz 600 that just went out and went 70mph to check his speedo,his speedo was right on the money,also a polaris twin 700 went out and checked his and his speedo was only off 1.8 mph.So any way I think the GPS is pretty cool,even though my sled is not as fast as the speedo says,but atleast I am not alone.-Harvey
 
about right compaired to my findings, we had a 1 mile plowed road out on a lake and a radar gun. I crossed the 1 mile mark at 112mph on my speed with my SX600R, the radar gun showed 103mph so 9mph off up top. This was with my stock clutch wieghts, 800 miles on the sled, and a 52/44 helix and loose track. My dads sx700R with reverse/electric start showed 107mph on the speedo and 102mph on radar. A stock 01' skidoo mxz800 (guy who owned the radar gun) turned 110mph on radar and an stock RX-1 ran 117mph on radar.
