My 04 LE will get to 65 in a hurry but it takes it a while to get as high as 70. Only made it to 70 a couple of times but many times have I been to 67-68-69.

Welcome to the site!

My 04 has hit 70 and just as you discribe hitting the high 60's many many times. I will say this much, my buddy who has a Honda 450R blows me away when we are toolin down the road! I watch my speedo and it's hitting 65,66,67, and he pulls away from me like he has some kind of freakin turbo-charger!

Yes the 450 probably will do somewhere in the 80 mile per hour range. There is an article in Dirtwheels February edition. But no need to feel bad that machine is probably hauling around 200 or more less pounds than our hefty Grizzlies. I come from a background of dirtbikes and earlier on 3 wheelers and for what it is I think the Grizzly is awesome.

I have heard a few people say they achieve speeds of 74-75 but unless mine is just slow or something they must have been going down a long steep hill. But then again with some modifications I am sure that 75 should be very likely attainable.

David,

Wow 74/75 MPH honestly would scare the living crap out of me on my machine. Seems like when I am in the 67/68 range I personnaly start getting nervous. All I can think of is, "if I wipe out now I am history" and I start backing off. My buddy on the 450 R is another story, he is a fat bastid like me 250+ range and that machine still flys when he is on it, despite his weight! I aksed him if he ever gets scared when he is pulling away from me flying down the road, he said,"**** yeah I do, YOU'RE CRAZY!!!" LMAO Yeah sure... and he says I'm crazy.

I'm staying around 40 when I'm going fast. Bumpy road, loose gravel, pot holes, and much caution. Guess I'm just getting old.

all those speeds sound pretty fast. I had mine up to 68 or 69 a few times on the speedo, but at 68 on the speedo my gps was reading 64. yamaha is pretty optomistic with there speedo. I noticed it 3 or 4 miles an hour off from about 30 m.p.h. on up.

I have an '02 that has been put through the paces and I can still get it up in the 60's when on roads between trails. There really isn't alot of places where I can get it up any faster so I don't know the top speed. I got it up to 58 one day in the woods and I had to ask myself what I was doing!

The Maximum I get is 108km/h (67 mph).
I am having it rejetted now during its service at Yamaha, ( I did not rejet when I fitted the Dura-Blue foam air filter and when I removed the baffles out of my exhaust and fitted the 2" power tip) I know I should have done it, so I am looking forward to trying it out this weekend to see if it affects the top end!

I hit 69 on the 04 after it had a couple hundred miles on it. Now 66 or 67 is top speed with the wind behind me. The 05 is yet to be tested.

I can't seem to get mine over 67 mph. Even with all the mods :^( Oh well I guess I'll have to keep on upgrading :^)

The belt and the rev limiter will keep your speed down.
Unless you get a cdi that will let it hit a few more RPM's and find a way for the rear pully to open up more your not going to go much faster.
I find the top speed debate funny..........after you put 1,000 miles on it check your hr meter against your miles and you'll find your average speed out on the trails is only 12 mph

It seems like everybody hits right around 69-70 when it's new. Once the belt wears a little, 65-67 is pretty typical. As the belt wears more and more, your speed should also decrease because you are reducing your gear ratio. Put a new belt on and your top speed should pick up if everything else is running good.

GrizKing, if you drink enough beer you could be going back in time.
