Suspension Torque Specs?
« on: September 09, 2019, 08:24:51 PM »
I have a 2018 CB500X

I just found and joined this site today because from the little I've been able to find on the 'innerweb' the shock bolts and triangle bolts torque is said to be 44 Nm or 32.45 ft./lbs. (it was likely specs for a 2014 - 2016 CB500R, not sure)

I'm interested in verifying the dog-bone torque spec's where it connects to the frame with the 17 mm nut with the Hex head bolt. I'd also like to verify the rest of the suspension bolts torque specs as well as the fork clamp bolts torque spec.

Does anyone have this information or can recommend a mechanics manual that has this information?  I'd feel better knowing for sure what this bikes spec's are. Any help is sincerely appreciated.

Based on what I could find, (though I'm not sure how accurate it is,) everything torques to 32 ft/lbs in the rear. The bottom fork clamps torque to 23.6 ft/lbs. and the top fork clamps to 16.23 ft/lbs.

Thanks.
JD

FYI: conversion 1 newton meters to foot pounds = 0.73756 foot pounds

(looks like that photo from CB-500-X is from a Haynes manual...)

Good Luck..

JPD,

Yes, If your down there taking on the task of checking torque, you should also take the time to pull the crappy triangle plates, and Uni link away from the frame, clean and inspect, and generously lubricate everything with your favorite Grease.

No this is not done at the factory, No this is not done by the dealer at general service or scheduled service.  This is your responcibility as the owner operator.

We have changed dozens of these Plates as Honda went cheap on us, and did away with the double dogbone design, and and gave us the Uni-Link crap with stamped,steel triangle plates.  They will start grinding away on your first long trip out, and shortly afterwards, begin to bind your linkage.

Do it now, and every 12000 miles and save your bushings, bearings and linkage.  I have the pictures to prove it, but I'm not reducing photos, as this server will not allow large Jpegs.

Cheers and enjoy the bike.

Thank you for the information.  Does anyone make a more robust and adjustable replacement for the rear suspension hardware?

JPD,

In a perfect world we could have upgradeable Linkage and Hardware for Our Beemers, our 500x's, our Triumphs and whatever.....

If you wanted to take the time to remove and replace, and had the Ultra Cool Machine Shop less than 100 meters from your house, and all they did was machine parts for motorcycles everyday......Then absolutely!

I'm not being facetious, I actually have one (a sub contract motorcycle machine shop) 100 meters from my shop, and they have saved my ass 100's of times with Milling out frozen bearings and Bushings in Swing Arms.

Then your answer would be: Absolutely YES!  Machine the triangles with easy to replace Teflon Coated sleeves, that are recessed and replaceable every 24000 kilos, and BAMM! Linkage lasts with just some good chain lube spray!

But in the real world, no one does it anyway......  Then you will end up at a Shop saying: "Hey, something is not right with my suspension" and you will already know the answer. Crappy Triangle Plates that are binding and froze bearings in the Uni-Link.

As Honda keeps shoving bigger engines up everyones ass, (see the new 2020 Africa Twin Recently?), No one is bitching about the crappy Uni-link and 1970's circa RSD forks with crappy damper tubes in them!  How about a Cartridge in the Front already, with Alternate Spring Rates, HONDA!!!!!???

KTM, Kawi, and a few others offer Alternate springs for the front and rear on New Bike Sales....  Why Not Honda?  Because, Honda loves Honda!

Enjoy the Bike, well done on the Torques, as we typically find them over torqued, and and bent bolts from impact guns!

cheers

P.S. although this suspension design is mostly Mike Hossacks design, it has potential.
