I have never ridden a stock BF 750 only ours with Fundy STD bore kit so I have no idea what the top speed gain was.

I agree with 70. My 07 did 73 on a slight downhill, and on flat i've been up to 67-68 before I ran out of road. So I would say no more than 70 on flat ground really, and that was stock.

I have gotten 72 with a bone stock one. and 75 with a dynotek...
But for the most part most will only run 70, for some reason this particular bike ran really good..

I have seen some only run 68 mph and some to run up to 70-71. With a cut clutch, you will gain alot more top speed.

no hes talking about a clutch mod like the VFJ clutch mod, not a clutch kit but a clutch kit for the most part will slow you down

Not my clutch it won't. but Yes, bolting in a clutch kit will slow it down top end.

witness it for your own.

Simple bolt in fundy std bore kit with trail cams with my clutch mod.




If you just did a Std bore kit with stock clutch expect 76-78 mph at the limiter pending on if it's carbed or FI

i thought he was talking about a "clutch kit" not the VFJ Clutch mod the kit will most likely slow you down the VFJ will add speed

I don't really know, at less than a quarter mile it is at 73

I have 27" Interco Reptile Radials on it which are pretty heavy. I know it accelerates awesome!!

Skip, your's now would be a the rev limiter way before the 1/4 mile. I'd say your's the way it sits runs 8.6 in the 660 at about 76 mph and the 1/4 would be 14.1 at about 83 mph on the limiter for the last 100 feet.

my old 730 prairie with 61 rwhp ran the 8th mile in 8.9's at 72 -73 mph consistantly (no wheelie bar and 2.0 60 foots). and the 1/4 14.6 @81

I have a stock 06 BF 750, it tops out around 63 MPH on flat ground. Tires are stock sized Maxxis Bighorns. My 05 BF 750 has clutch spring upgrades, dynajet kit installed, and Muzzy exhaust, stock size GBC Dirt Tamers pulls 74 MPH on flat ground, and gets there much much quicker than my 06 BF750. I also have a stock 05 Suzuki King Quad 700 with stock size Maxxis Bighorn tires, it will top out at 73mph on flat ground, but is a dog off the line. But in it's defense, it is smoother all around that the BF's are. And gets much better gas mileage. If I am hot rodding and going riding in the mud or sand, I take the BF. If I am going on a long distance ride, I take the King Quad. :D
