Here's a question for the techs among us...

Do any of you happen to know which SAE grade of front fork oil our bobbers come standard from the factory with?

I've been contemplating the upgrade to the Matris F15K fork kit because of it's adjustability etc.
However, I must say that I'm pretty happy with the factory set-up and I'm also convinced that these bikes are roughly set-up for riders of somewhere around 70-90kg body weight; round about; at average every day riding conditions.
I'm in that category; 75kg body weight, riding conditions everything from commuting to touring to afternoon blasts to the German North Sea coast or Harz mountains etc.

The reason for my question is; I think the rebound damping in the front forks could be a bit lighter because on some rough surfaces/bad roads, the forks compress, but don't rebound quick enough IMO; causing the front-end to hop around quite a lot.

So if the standard oil is an SAE-10, I'll try an SAE-7 or 5 before going the full monty and buy the Matris. After all, it's a cost thing of course and I'm pretty sure I can get where I want to go by trying a different oil thickness.

Thanks in advance for any replies.

Cheers!

You thought about trying Emulator's first? - damned sight cheaper if they work, not buch of a loss against a Matris fron end rebuild if they dont?

Not saying these are the right ones but... YSS PD Triumph Bonneville Thruxton & Scrambler Fork Valves Fork Cartridge Emulators.

Before i purchased the Matris set, i also looked into other options.
Free Spirits sell these:
https://www.freespiritsparts.com/en/triumph/triumph-classic-fork-upgrade-kit.html

The issue i had, is that no one could really explain to me (in a satisfactory manner) WHAT they do & IF they actually work. There is very little info out there.
So in the end i opted to go the Matris route.

Thanks mate, I'll look into them too

Matris also makes an adjustable fork spring kit with is their version of an emulator, springs, spacers and pre-load adjustable fork caps.

Just Google: "matris adjustable fork spring kit." You'll have to scroll past all the "mattress" paid-to-be-at-the-top links.

You mean to get to the link to your web-site...? Nice try mate.
If you read my original post again, you will see that I know about the Matris stuff F15K etc. I was asking a completely different question.

Your impudent advertising attempts here have been reported. :wink2:

Yes, aren't they lovely...:grin2:

Strange to see actually, that Öhlins have a fork kit but no rear shock yet; and Wilbers have 2 rear shock models but only fork springs; all for the Bobber. Who knows what the future will bring. Of course Matris have had complete upgrades for both front and rear for some time now, so we're pretty spoiled for choice.

It's great to see such high-end companies developing serious upgrades for our bikes.

The only thing I don’t get is it says it doesn’t come with the springs sooooo what do I do there haha. I would assume they would recommend a set

Yes, depending on your weight and riding preference i believe.

The FKS setup from Ohlins is very nice. We have installed a few sets on older triumph models. With parts and the special fork oil required, the price is about $800 in the US.

Can you comment on the spring required?

Ohlins provides recommended springs per rider weight in the install guide:
