Smile Pre-loading Reaction Link

Reading through tech articles in ADVrider I came across this step in reinstalling the rear drive. " Load 87kg (187lb.) onto free standing motorcycle and torque reaction link bolt to 43Nm. (32ftlb.)
A heavy person sitting on the bike is required for this step. It is important to pre-load the strut, or it won’t operate in the correct flexibility range. "
I makes perfect sense, but I haven't seen it detailed before. When removing the rear drive and undoing this link, the front one remains done up, and has quite a strong resistance to movement, hence the procedure for torquing up the rear.
Anyone here like to comment ?

I'll comment. . . I'm deeply offended that you refer to a 187# person as "a heavy person," not.

Tony, point taken. It was the comment as per AVd thread not mine. I did hear once that the OEM Showa shocks are set up for the average 82kg rider. That's wearing all the gear, natch. Cheers

I was just breakin' your chops, but your kind reply is appreciated.

I'm down to 240-ish from 290-ish, headed for 210-ish. Seems odd that they use the weight they do for a "standard" rider. Many of the folks I've seen are built more like me or even more so.

We had my FD off, in December, to drill the SC weephole. The reinstall went smoothly and we never pre-loaded the bike to install and torque the reaction link.

The holes line up and you tighten it up. I don't understand the logic for pre-loading the suspension.

Perhaps greater minds will enlighten us!

Nope, just eating better. Cheerios or real oatmeal for breakfast, pretty much anything for lunch, and something sensible for dinner, and not after 7pm. Cut out the three or four cokes a day in exchange for two or three a week. Cut our the couple of candy bars a day in exchange for one or two a week. And the big one. . . stop eating when I get to feeling full, no matter how good it is.

It's been over a year, and I find myself making better choices and negotiating with myself over various treats. I would say that the behavioural and perspective changes regarding food is what is carrying me through.

We now return you to your regularly scheduled thread . . .

Hmmm. I never did that on any LT FD, and just re-checked the service manyual. Nothing is mentioned there about pre-loading the bike.

Is this a procedure for the newer R-1200s with the reaction link on top?

Tony, that is because BMW uses European standards where people in general are slimmer (because they walk more, have more vacation time, blah blah blah... ). Note that European are also a bit shorter in general. It would be interesting to see what changes they would make to follow the 80/20 rule after a serious focus group (assuming that respondents are honest with their answers regarding weight and height! ).

European normal?

Gilles said 'in general are slimmer (because they walk more, have more vacation time, blah blah blah... ). Note that European are also a bit shorter'

So how do I fit in at 195 cms and 21 stone? Though to be honest I need to do a Tony ;-/
