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.
