Suspension Options? 1999 CBR600F4

Yeah the guy at the rebuild place said the Nitron is better, but then again, it's £100 notes more so there's the reason... yeah think I'll be going Nitron unless anyone else can give an additional option? With it being an older bike, I'm slightly limited I think.
 
can i ask why neither rear shock has a remote reservoir?

I thought they made a big difference to the performance, also am i wrong in thinking the f4 has a shock with remote reservoir?

pugheaven how much did the fork rebuild cost btw?

Hey mate I got a small service and some re wiring done but think the fork service was about 150 ish. Yeah its kinda confused me, my current setup as this reservoir that you can see but these don't I'm assuming they come with one, tbh know nowt about suspension on bikes. I'm a tard
 
i didn't think you could get them rebuilt

what about the Maxton shocks? anygood

The original Showa socks are are not really designed to be rebuilt, but they can be. There would be no point in Gold Valve kits being made for them if it wasn't possible to fit them.

Maxton also make excellent quality suspension components.

You can buy a Nitron (and Maxton, Ohlins, WP, Wilbers, Hyperpro etc.) with a remote reservoir, but they cost significantly more. The standard Nitron will be better then the original shock anyway, and vastly better than a tired original shock.

A remote reservoir provides increased oil capacity since it eliminates the need for the floating piston and gas space within the damper body. It also permits some damping controls to be moved outside the damper body.

So to ask a noob question, if I buy this Nitron kit, will I need anything else? I'm assuming take the original one off and replace. However what do I do with the damper gas thingy that's on the side of the bike? Bin it?
 
yh its either oil or gas expansion chamber,if its attached to original shock it can be removed/not needed as the new shock doesn't have one

Right ok, so that new one, say the Nitron has it all inside it then? I think the fella was saying it's gas and somethings gone that he can't regas it. He's not bothered as he'd make no money on putting a new one on apart from labour... however he said you can't rebuild the original OEM (or wouldn't bother lol).

So, think this week I'll order this Nitron one then...

He's wrong, but it's a common assumption. It can be a bit destructive getting them apart which is why you sometimes have special replacement components that come with the gold valve kits. You replace the end of the reservoir for a part that has a schrader valve so the rubber bladder inside can be re-gassed.

The entry level Nitron dampers have the pressurised gas within the main damper body instead of an external reservoir, so no other parts are needed. The original remote reservoir is simply held in place on the frame with a hose clip and when you remove the original shock the reservoir will come out with it.
 
As Dogbreath said most units can be rebuilt.

Have a chat with MCT suspension, I'd be very surprised if they can't strip, service and rebuild it. The stock shock on my Blade will be off for a service there over winter.

Personally I wouldn't drop £5-600 on a new shock for a bike of that age, just get it rebuilt.
 
depends how much you like the machine and how long you plan on keeping it

its steep for a shock but how often do you have to replace them?

at 22k im surprised it went that fast tbh unless its just down to age,have no idea what condition mines in but feels alright to me

Most OEM shocks are well past their best by that sort of mileage. Short travel and high spring rates means the oil has to work very hard.
 
wouldn't it fail an mot though?

im also wondering how the nitron shock would hold up to a few wintery salt roads
 
soak it in acf50 then wrap it in a shock tube, also a decent hugger will keep it safe through winter.
 
They won't fail an MOT and they are so knackered that the back end bounces around (or if they are leaking oil). Handling will be affected well before that point, especially on a track.

What will not fail an mot ?

Did you mean "They won't fail an MOT UNLESS they are so knackered that the back end bounces around (or if they are leaking oil)"

I had an RD250 32 year ago that was like riding on a pogo stick :D
