| I have read the other posts about this problem, some have it some don't, that don't seem right if you ask me. Did they forget to grind 1 thru 4 and 6th? This thing sounds like a T-10 Muncie Rock Crusher from the 70's. Obviously the fairing and metal around the tank/frame acts as an echo chamber, it's still loud enough to cancel out the Stage II exhaust thru 1-4th, why is 5th quiet?? It has to be the finish on the gears. Anyone ever ask Victory about it? |

San Antonio, TX | This is how it was stated to me.
The 106 Freedom engine has more HP and Torque then other V-twins. This power should be transferred using straight cut gears, since they can handle the added power, in first through fourth gear. Fifth gear is spiral cut so it is quieter. I do not know about sixth gear but I suspect it is straight cut.
The more you ride the quieter the gears get.
I have not heard of a single transmission failure on a vision. None.
There is a still pocket of air near your ears so you CAN hear the transmission.
All in all.....Just ride it and have fun.
Ride Safe

New Bohemia, VA | Thanks RT, I don't think I heard about the cuts until now. I like my solid feel transmission as I can be fairly rough on stuff as my childhood toys were real bulldozers. The transmission never feels like it is going to let me down and is solid as a rock in every shift. It also tells me when I'm in fifth and I can consentrate on the task at hand, often merging into traffic.
Since I've got my exhaust fixed I feel the benefit of the solid performance of this motor as though I got some upgrade. Between that and having a new belt I've had some exciting entrances onto the interstate and when I'm getting down on it, I back off when I hit fifth. Fourth gear is topping out at 75mph's and I know I'm at speed then. |

San Antonio, TX | spot32,
I only have 10, 800 miles on my Vision but varyder has over 46,000 miles on his with no transmission problems.
It is just the sound of power being transferred to the back wheel.
So get on the Vision and ride.

| Thanks for the info, it makes sense.
I noticed you have Stage i level 2 pipes, I just put them on getting back fire when moderate acceleration, none when you run thru hard. Is that the timing or air flow ? |

If you go to the service manual which is located here in the tech reference forum, in section 10 you will see photos of the main transmission shaft gears and the counter transmission shaft gears. They are straight cut gears, as they are the most robust type of gears for the transfer of power. In those pictures it shows power transfer through the gears as per each number of gear, like 1st, 2nd, etc.... It is very interesting, if you want to know. Why is 5th less noisy, power transfer is straight down the main shaft.
Now in my own opinion, the noise of the transmisson is reduced by the number of miles you have on the bike,more miles, less noise. Also, in my opinion and I don't want to start anything here, the oil choice makes a difference. Oh and I almost forgot, the faster you go, the less transmission noise!   |

Pitt Meadows, BC Canada | My first car was a Jaguar XK-150. First gear simply HOWLED HORRIBLY. Again - straight cut gear to handle the power (of the day).
When I first rode my Vision - I understood that from the git-go. It grows on you if you let it - all part of the package. An engine that thumps and makes fine power, gears that DON'T sound like a Buick Dynaflo, occasional chirp out of the final drive. .... THAT'S when you know you are driving a real motorcycle, not a 2 wheel Lexus. |

San Antonio, TX | VisionTex,
So I was wrong about 5th gear. Thanks for the information and the pages in the service manual. 5th gear runs down the main shaft.
Thanks! |

on the edge of Los Angeles | +1 on VTEX.. I see too that 5th is straight thru & no reduction / multiplication therefore the quietest and smoothest of all gears.
you need to have 10,000 miles on this bike before it all quiets down and gets happy. Yes 4th is the noisy gear but now with the miles I have it's not an issue. Changing oil sooner than the recommended intervall in the early stages helps in elimination of suspended metal particles in the oil.
Don't want to scare anyone but I did have a engine lathe repaired with new drive gears in the crossfeed and the "technicinan" iintroduced a fine lapping compound into the oil to accelerate wear to get it to run smooothly.
I think with our bikes letting it do this naturally is more recommend.
Just Ride it and report back after 10,000 miles |
