V-Max vs. Venture Rear End

The V-Max rear end ratio is decidedly different. The stock Venture rear end gearing has always been 10 teeth on the pinion gear and 33 teeth on the ring gear, which is a 3.3/1 rear end ratio. The V-Max has 9 teeth on the pinion gear and 33 teeth on the ring gear (same) resulting in a 3.66/1 rear end ratio. The bike should seem quicker! Now the good news is that this may well be an improvement even to gas mileage, particularly with two-up cruising at 65-70 mph.
One of the V-Max tuners, John Furbur of Rocky Mountain Sportmax (www.rmsportmax.com) says that the Venture is overgeared and the V-Max rear end does the foregoing. For different reasons, the Venture rear seems to give better performance in the V-Max. I bought a used V-Max rear end from Rocky Mountain Sportmax, but have yet to try it. I want to try it in an A/B test but have not found the time yet.
I would be interested in your experiences. Please keep in touch..........Rey Kirkman

Can V-Max Rear End Fit In A Venture?

The final drive ratio of the Venture is 3.3:1. The final drive ratio of the V-Max is 3.67:1. The entire rear end units (called the "pumpkin") interchange. You have to buy the entire unit with intregal ring and pinion gears. My understanding is that the V-Max drive shaft is of a different length..........Rey Kirkman

From what I heard talking with another Venture owner over the past weekend, is the V-max rear is thicker, 16mm to 14mm. He did the change because he kept breaking the driveshaft. After replacement never had anymore problems............Dave
