Speedmaster 2020 Any Upgrade Suspension

I just did a little ride up the coast around 400 km and found that my new bike has very harsh suspension which lead to me having a sore back for about two weeks .(This bike is going no where )
What I have been looking at is a Lowbrow custom spring seat which I think would look very cool !
Has anyone put a sringer seat on a speedmaster ?
Or can I get a replacement suspension for this bike ?
Cheers

 

Hi Greywolf55 thanks for the info will check it out

Cheers

 

Hi Dartplayer have move it to 3 and will be testing it today Sunday
I did check out the Matris rear Mono shock and now I know I can get a Mono shock it's a big help cheers
I did check out Greywolf55 Touring seat yes it looks great but I'm still looking at a single seat set up
The rear rack you told me about was great but our dollar has drop big time so I will wait to it goes up a bit I'm going to buy the rack cheers Dartplayer

 

Thanks Greywolf55 I check the seat out thanks for the info
Not sure if this seat will take shock wave out of the bump, I have been told
Gel seat is the way to go I have seen a gel seat for a $100 less US than
the Corbin but I will keep this seat in mind cheers

 

Hi Dartplayer I did a little ride not sure if it helped as I didn't have time to ride the same road but if the weather is good this Sunday a group from work are going for a run up to Kaikoura and that the road that I rode before, so with this new setting that I'm on now it will be good test and on the way back I move it one more click just to see if improve the ride and if this works ok then I look at a new seat maybe a gel seat, Greywolf55 gave me a link for a Corbin seat but not sure it would absorb the shock wave like a gel seat and the seat would be a cheaper than a mono shock but what ever I do NZ dollar needs to go up cheers

 

Hi XCaTel I'm 90kg and when the preload was set on 1 the shock went up my back it was a very sharp shock and when you have over 100 sharp shocks like that it turn out to be a bad ride but when I adjusted the preload to set 3 the ride did seem to a better ride. I still get a odd sharp shock every now and again , also the bike has travelled 3000km now .
I was told by a workmate that he thinks the bike was bottoming out I'm thinking to put it up setting 4 still not happy with the shock absorber but will leave it till after my xmas trip as it get a good work out .
Maybe I've been spoilt as I had a Tiger XRt before the speedmaster and the Tiger was a 1000km in one day bike ,the speedmaster is about 400km day bike but I'm happy with that !
