    Driveline Backlash (How Much Is Too Much)

    I just wanted to see how much driveline backlash others may have on their TTSE's.  I perceive that there is an excessive amount of  clearance somewhere in my drivetrain, causing excess noise and sloppy power delivery.

    Although not really precise, I placed the bike on the centerstand and measured the movement of the rear wheel after placing the transmission in low gear.  I rotated the wheel forward and marked the wheel location at the outer edge of the rim, then rotated the wheel backward and again marked the location on the wheel.  The amount of backlash I measured on mine was  42 mm.  If some of you Forum members get the opportunity to check your bikes and report their findings; maybe I could determine if I have a problem, or maybe this is normal.  My dealer's technician rode my bike, and claimed that he thought it to be a little noisy, but there was no follow up.  If others have similar amounts of clearance, then I'll just accept that this is normal for a TTSE.

    I have 42,000 miles on my TTSE and I measured mine as you described. 40 mm was my reading. These bikes are noisy compared to many. I came from a BMW 1150RT and the change in engine/driveline noise was pretty noticeable.

    This should be interesting  :084:

    I have just over 10,000 miles and it measures 40 to 42mm.

    Thinking of my previous shaft drive bikes I don't think that that amount of movement is unusual to be honest,......I'll check my Trophy and report back here. :002:

    Well, that's three different machines with essentially the same amount of driveline backlash.  I guess what I perceived as a potential problem is quite normal for the TTSE.  My last bike was a 1500 Goldwing; the drivetrain was completely silent and smooth at well over 108,000 miles.
    Thanks guy's for taking the time to check your individual machines.  I guess a little extra noise is what gives the Triumph its character.   :153:

    The Goldwing uses helical cut gears and the Trophy uses straight cut gears. Helicals are much quieter and that's one reason for their use. Straight cut are supposed to be stronger, but you get more noise. The 1500 also had more extensive bodywork to help shield the rider from any noise. When I went from my 1500 to an RT I thought the RT was noisy. When the RT went down the road and I bought the Trophy, WOW, this thing is noisy. The Trophy is a very vocal machine  :169:

    NavyDad, now you see why I was concerned.  Knowing that all of the Trophy's make noise will allow me to just ride and enjoy the Triumph, and not constantly be wondering when it was going to grenade itself going down the road.  Thanks all of you for your feedback.
