Staff Blog: Sorting our my saggy-ness

 

You might have seen my latest long term review published in July 3 issue of MCN.

I’ve been having a few issues with my suspension and Senior Road Tester, Michael Neeves, gave me a few tips on how to adjust the front and rear sag on the Yamaha Fazer8.

So getting my hands dirty I got to work with a tape measure and spanners.

I thought you might be interested in my little photo guide giving you details of what to measure and where to make adjustments  if you fancy doing the same.

Initial measurement to find fully extended figure (Fig: A1 & A2) (Photos: 1 & 2)

We measured the forks and shock at their full extension. Neevesy lifted each end of the bike up by balancing it on the side stand whilst I measured the amount of exposed fork slider at the front and at the rear we chose a point between the subframe and swingarm.

Second measurement needed to find static sag (Fig: B1 & B2) (Photos: 3 & 4):

With both wheels back on the ground and the suspension compressed under the weight of the bike, I steadied the bike upright and we measured the same points at both the front and rear.

Final measurement needed to find rider sag (Fig: C1 & C2) (Photos: 5 & 6)::

Keeping the bike upright I then sat on the bike, lifted both feet and balanced whilst Neevesy measured again.
