Previously in this thread, the rear suspension of the SH350i has been criticised. I would like to point out that the rear shocks are listed on
bike-parts-honda.com as Showa units.
I recently exchanged my 2016 red SH300i for a gloss white 2021 SH350i with 4k miles on it.
I am a long-legged 6'3" solo rider and overweight at 118Kg but found the suspension very good. I have them on the 2nd lowest setting and use an "Airhawk" style cushion on the seat (cheap inflatable off eBay). I have a bad left hip and knee yet have ridden over 200 "B" road miles in a day without any real discomfort.
I also fitted the OEM screen and knuckle guards. I found the screen 3 cm. too high, so cut that amount off the top and it's just right for me to look over. On my previous SH300i, I cut too much off and it was very noisy

I cured it with a
*37cm wide* deflector clamped to the top of the screen... again, cheap on eBay.
So far, two things I don't like. Firstly, the headlight. It's aimed far too low... I don't dazzle oncoming cars even on full beam! (I know -maybe it's my weight

) A nightmare to ride on totally dark country roads. I found the beam adjuster but it's impossible to get to without either a special tool or removing the front wheel and mudguard. Bad one Honda

.
Secondly, the noise. I've heard some people say it's the exhaust but, leaning to my right while riding, no change. Leaning to my left and it's coming from that side. One owner took his bike to Honda and they said it was normal for the model. They said it was to do with the heavy duty rollers in the variator?
Maybe Dr Pulley sliders might be an answer.
