Default engine vibration

Just bought a new 2011 grizzly 450 love it, but i notice there is alot of engine vibration even when reving....Seems to tire my hands after a little ride. I sure hope this is not normal. It is a bit much. Why is there so much vibration hope this goes away after breakin time...

Default Huh?

Have you talked to your dealer about the vibration? Did you ride the quad before you bought it? There may be something not right with it if it is as bad as you make it seem!

If you just bought the thing let the dealer check it out. I have an 07 so no eps and a ton of work on mine and there is no vibration like your stating, at least not that I can feel in the bars.

When you swich from a IRS (Independent Rear Suspension) Grizzly to a SRA (Straight Rear Axle) Rancher you will just switch the vibratiion from the bars to your a$s. LOL

The 450 Grizzly is more of a competitor to the 500 Foreman than the 420 Rancher. the Rancher has less power,smaller 24" tires, rear drum brakes,no low range and no AWD diff lock.

Sure seems to be one heck of a down grade for buzzy handle bars.

someone told me to have the dealer check the to make sure the crank is balanced. That is a normal thing with the 421cc liquid cooled engines. Anybody back me up on this? Before i ask the dealer about it and look like a idiot..

Do you see the bars actually shaking when you have it running? Being an 2011 not sure if you have the eps or not but it could be possible there is an issue with it. I would just take it in and find out if it's normal cause without doing that no one will be able to help you much. There could be something wrong or it could be your just not used to it. I know I changed out my grips to rogues and they are real comfortable. I can also ride 100 miles beating the hell out of it riding real aggressive on rocky trails without eps and not have my hands hurt or be tired from it. What were your riding before?

The 421cc engine does vibrate a little more than other Yamaha engines for some reason....

If you are that worried about feeling the vibration in your handlebars - just go out and by a RoxSpeed FX anti-vibration handle bar riser

ROX Speed FX Elite Anti-Vibration Risers - DennisKirk.com

I bought one - not because of the vibration - because I used it on my sled and it ROCKED! So now it is on my quad - I get a 2" rise and the benefit of anti-vibration again not due to engine but the rocks etc that I hit.
