Handlebar risers
 

Hi, I bought handlebar risers from Wunderlich. And their fitting instructions say:

For BMW motorcycles this value is usually 21-22 NM(15-16 ft/lb) for 8 mm bolts.

But I also have a Haynes service and repair manual and that books says nothing about torque settings. Do I need a torque wrench for this or can I just thighten these bolts by hand (feeling).

Thnx

Most torque wrenches are woefully inacurate and are only used so you can blame something else when the threads strip. 22 Nm is there so the factory can't send them out loose, its the engineering equivalent of "some".

Unless you plan on rebuilding the motor next week and/or can afford a £200 wrench and calibration stuff to go with it, do it by feel. If it isn't tight enough they'll move when you swing on them, you don't need a gauge to tell you that.

Edit to add: if it worries you put a pen mark from the bars onto the riser and across the bolt head so you can see if they move.

Hey thanks. Yeah I'm a complete mechanical noob. But some day, some day I tell you.

HI when you fit your risers put the top clamp on and lightly tighten each bolt try to keep an even gap front and back doing each bolt up a little tighter as you go then you wont put excessive strain on any one corner or side .ROB

Thanks for the tips. :thumbup1:
