So……I’ve noticed recently the front forks are starting to ‘patter’ a little, even over relatively slight road imperfections. On really poor surfaces, I’m getting properly shaken around!!

I don’t think it’s the dreaded steering head bearing issue, but it has got me thinking about the front forks, and the fact I’ve never done anything with them. Isn’t fork oil supposed to be changed every two years? Has anyone ever done this with their SCR……?!:rolleyes: My bike is coming up to 5-years-old (as they all are, I guess!!!:ROFLMAO:), so it could easily be said that it was about time…..

At the same time, I’ve been watching some Royal Enfield videos on YouTube, by a guy called Stuart Fillingham (don’t worry - I’m not getting one……). I watch them as they are generally good quality, interesting videos; he doesn’t live far from me (so I often recognise his routes); and he is amusingly bolshy.

Anyway, I recently watched a video of his where he installed a ‘YSS Fork Upgrade Kit’


It makes for interesting viewing, and he seems to be very pleased with the results. People installing them on other bikes seem impressed too.

Naturally, I assumed there wouldn’t be a kit for the SCR (aka “The Great Forgotten Motorcycle” TM), and nearly fell out my chair when I saw that there was!!:

From what I understand, the ‘valves’ (above, in black), go in the forks before the replacement (and progressive!) springs, and sit on the damper rod. They then better regulate oil flow and, in a way, ‘emulate’ cartridge forks. You also get fancy new, adjustable fork caps (silver, above), which will look very trick!

I’m a little concerned whether these new fancy caps will fit without fouling the underside of the bars, but fortunately theres a YSS dealer not 15 miles from me, so I toddled over there yesterday, and spoke to a lovely guy (shout out to Brook Suspension!! You are being redirected... ) - they didn’t have an SCR kit in stock, predictably, but he opened up an Enfield kit for me, and we offered the caps up to the bike, and came to the conclusion they might jjuusssstttt fit. Of course, if not, I could just get some slightly offset risers, so it’s not the end of the world anyway.

Incidentally, when the guy came out to the bike, and said how much he liked it( :)), as well as the usual “I’ve never seen one in the metal before”, he also told me he had had another query from an SCR owner last week, but about someYSS rear shocks this time……anyone on here, I wonder??? They do look nice…..

So, I think I might go for the fork kit, and add it to the project list over winter (along with the seat). Of course, updates will be provided in due course, but if it doesn’t feel like Ducati semi-active Skyhook suspension afterwards, I will be very disappointed!! :ROFLMAO::ROFLMAO::ROFLMAO:

Comments, of course, are very welcome (and expected!!)

Do It Ben. Be the first. I installed progressive springs on my 95 Virago XV1100 and was completely surprised by how much it improved the ride. So I might add it to my list one day for the SCR. But then I still have the stock exhaust....:geek:

You dont need the caps just get the springs and emulators (valves), put a cut to length spacer on top of the spring to adjust the preload.
I've put race tech emulators and progressive springs in a KLR, they were a massive improvement from stock, im sure the SCR will be the same with the yss stuff. I put ricor imtiminators in my dr with shortened stock fork springs, again a massive upgrade from stock both are very similar to the yss valves.

Im going to put 15 wt oil in my forks this winter and raise the oil height by about an inch to stiffen them up, mine are super soft. This wont be near as good as the yss kit but will make them quite a bit stiffer, I dont want to spend a bunch of money modding the SCR.

Yeah, I considered foregoing the adjustable caps, that’s another option……but the replacement caps look very trick!! :cool: We’ll see…..the YSS kit comes with its own spacers too, so would try them first, too.

Unless they're dirt cheap im not a fan of preload adjustable fork caps, you only adjust them once when you install them.
The fork spring needs 5-10mm of preload if its the right spring rate. Some bikes come with preload adjusters on the forks now so you can get away with running the wrong springs for your weight but if your getting custom springs you wont need to adjust them.
