C400X Suspension options

[ELvir]

Hi all,

Ive purchased a C400x with sole purpose of riding with my wife. Now, the bike is doing an OK job in handling the weight of both of us. I had to set the pre-load to the stiffest setting and even then it bottoms out in the slightest of the bumps.

My question is, what suspension options are there for this bike that would improve the overall rear. I have seen Ohlins and I am really not interested in that level of performance/cost. I just want something that does a better job for 2 up.

Since I joined this forum about two years ago, off-hand I only recall member @byee having replaced the rear shocks on a C 400. This is the thread I'm referring to, which you may find useful (click the title below, to view the full thread):

Thread 'YSS Rear Suspension Upgrade'

Aug 31, 2021

I upgraded my rear suspension with YSS shocks. I considered the Ohlins but decided not to because of the price…..$1,100 USD vs $510USD for the YSS.

I only ordered the rear shocks and not the front cartridges. Wasn’t sure if the costs justifies the costs….cost of the YSS cartridges and installation fees.
Unlike the rears, the fronts only have a compression setting with no rebound.

I’ve ridden about 700km on my C400GT since I’ve installed the YSS rear shocks. There’s been a significant increase in how the bike handles and rides. I’m now getting absolutely no air time….my butt now...

I have a 2019 c400gt and ride with pillion most of the time and find the suspension is a bit on the soft side with it set on max preload, any settings other it bottoms out. YSS springs are 150kg i understand although not sure what the standard springs are rated at. Thus have never been able to make a definite choice

I just recently installed a HyperPro SP-BM04-SSE003 suspension lowering kit on my 2019 MBW C400X. It lowers the scooter by 25mm(1 inch).
It has been a great addition for me(a short 5'6" rider). The bike rides better and factory control has not been affected. It does lean a little less on the side stand, but overall it has been a very positive modification.. Cost was about $700 (CDN) ( $380 for the parts, and $320 for professional installation )

On my GT I also added the hyperpro shocks. Tremendous improvement. YSS makes emulators and springs for the front.
