I don't know anything about this company, but it looks cool. Video on their webpage. Seems a much more exact way to go than guessing with a ruler. http://www.tru-tension.com/motorcycle/
That's interesting. But. Everything I have read suggests a slack measurement between the tight spot on the chain and the chain protector in the swing arm. Is that the measurement they are using to set that device? Hell. You are a working stiff. For $35.00, go out, buy one and report back to us.
That item simply takes a percentage 'sample' of overall slack, and frankly looks like it cost all of 59 cents to make. $35 will buy a super nice ruler however!
Not seeing the value. Adjusting a chain might be the easiest semi-regular maintenance item to do on a VFR. I can get a lot more value out of $35. If someone really needs this, do they really need to be riding a motorcycle? To each their own.
That has to be the most worthless POS I've seen in many years. In an ideal world where the countershaft sprocket and swing arm pivot are in line, this thing might work. As it is you have to adjust the chain when it is at it's tightest point, which would vary from bike to bike. On most bikes the tightest point is at the point of most travel, so you'd have to compress the shock to it's shortest height, then use this thing. Overall a major waste of money.
sorry, man. This falls into the category of $150 HDMI cables and something sow would probably buy inbetween measuring gas fill ups with a pyrex beaker. With rear wheel on the ground (or rear stand) you should be able to eye appropriate slack, a Dollar General ruler will work fine if you want an actual measurement as per Honda instructions.
I kept seeing this pop up on FB and I checked it out. To me, clever idea but not necessary, I spent a few bucks on a measuring tape that has both inches and mm, better investment IMO.
It seems to me that its an answer to a question nobody asked. Agree with FJ12, good in theory, but whoever designed it does not understand motorcycle suspension.
