Well there ya go. two people with exactly the same setup 15 tooth 22 rears and 6 mph difference with the same rev limiter?? What gearing calculator are you referring to?? Is there one on this site?? Honestly interested not wanting to prove ya wrong but wanting to calculate a couple other machines.

 

20" Turf Tamers 1 tooth over on the front sprocket ( 17 tooth ? I cant remeber..) 38 tooth rear sprocket and the GPS said 88mph..
20" Extreeme Haulers 10 Paddles with the above gearing and Mr GPS says upper 60s......

Take it for what you will ....

 

holy 88mph wow thats high all i can manage to hit with 22 tires and 15 tooth sprocket is 82mph at the rev limiter so how are u getting more with the same set up???

 

Like I said ... Take it for what you will ! I Know that my GPS is on the money by using it while driving down the road. I can hit the upper 70s any time on flat surfaces ( not sand ) and constantly get the same reading, so I can only assume it correct.
If you know much about how GPS works or how its prone to a mis-read than you need to take the 88mph with a grain of salt. It has read out that I have been to 92mph before and I can assure you that it WAS NOT a 92mph run. So once again ...... take it for what you will.

D.R.650 how did you clock your speed? radar gun ? GPS? ...

I would be curious to find out what other people have been able to max out at with a GPS on board ???? any takers ?????


One thing I might add ... 22" rears , one tooth over on the front and 34 on the rear and 45 +/- horse power isnt going to get you the top speed that the gearing calculator claims. I would guess that one would run out of HP before pushing those gears to the end.

 

that was on hard pack with nobbies. My GPS is right on. I have checked with my trucks many different times. If you have a stock bike it might be hard to hit 8500rpm in 5th gear. That speed was with my stage II with the RW CDI. All I know if that I want to go 0-60 fast as hell and don't even want to be on my quad going over 80mph. Seach for gearing calculator it should pop up on yahoo. Check the treads I know it is out there. I think Marky has it on his web site.

 

everyday and practically everytime i ride i hit 82mph atleast once in a ride i love the speed[img]i/expressions/face-icon-small-smile.gif[/img]

 

the online gearing calculators have some incorrect parameters for the DS650.
