Greetings!

old topic! Or new topic for anybody that has not done the suspension upgrade!
Being about 200lb with gear I started feeling the bumps on my GRiSO 2017SE. Cranked the pre-load, and played with the rebound and compression as many posts here report -- some improvement.

I was about to pull the trigger on Matris K series when I found the Mupo...

-- Anybody has experience with the Mupo rear shock on a GRiSO??

I found some really good prices... but still very comparable to a Matris K. I do not think I need or would appreciate the Matris R.... -- I am a road only mildly 'aggressive' driver Smile -- doing 3 or 4 trips per year of 2 days, but mainly twisters around the hills where I live.

MUPO AB1 less than $800 with shipping to US CA.

or
MUPO AB1 EVO.. about $850 with shipping to US CA

Also -- how hard is it to install it yourself??? I can manage to get the bike up and steady.. Do I need any special tools???

Thank you!
Giuseppe

Hi Giuseppe...can't talk to MUPO performance (I fitted Matris K) but there are lots of threads about fitting methods - none require 'special tools' but just different ways of jiggling and deciding best size standard spanners will fit tight places. It's either top-down that IMHO risks upsetting wiring runs & plastic fittings & PITA getting the airbox inlet rubbers off/on  OR bottom up which is a PITA wiggling shock in/out with various levels of removal (wheel, exhaust) and support stand height options depending how big the shock is. In past I've managed to fit a stelvio std shock bottom up despite it's lot harder to wriggle as it's longer. Believe you can also drop the shock all the way out the bottom if you can get the bike high enough & remove dog-bone (which can be a problem). Check the threads and can PM me if you want a write-up on doing mine (PDF)...no guarantee it's best practice but works for me.

Thank you so much.... seems quite involved.. will look at threads on this forum then ... I will probe any local mechanics if they are familiar with this type of work....

While it may appear complex it's really pretty straightforward. If it hasn't been done yet fitting a new shock is the ideal time to pull the swingarm for greasing of the shock linkage and swingarm bearings so you can kill two birds with the one stone.

I will go thru the service manual as well...

In the service manual I see :
Special Tool 05.91.26.30 for the fork pin ring nut -clutch hub... to take the swing arm out and do the proper greasing.... that I would have to track down.

Nah, you can easily unwind the spindle with a 'C' spanner.
