Gsx-s 1000 shock absorber for 98 Vfr?

Hello , my low value 98 Vfr rear shock is tired but I cannot justify the cost of a aftermarket replacement. A Gsx-s 1000 shock looks a fairly close match, has anyone tried this option? Many thanks Andy.

 

Likely no one has tried it because it isn't any kind of upgrade. It's still a basic OEM shock.

How do the lengths of the compare? What are the dimensions of the eyelets? Are the two bikes similar in weight?

If somebody gave me one off of their new bike when they upgraded, and I happen to have my super tired VFR shock on my bench to compare... maybe. And only if it was near identical but was perhaps 5-10mm longer.

 

Rebuild with new gas is about £160 if that helps

 

A decent suspension guy can rebuilt it for you, and respring and maybe revalve while they're in there.

 

Hello and thanks for your replies. £100 buys me a unused OEM gsx-s shock which is 5mm longer and the bike is of a similar weight. Looking at the yss comparisons between the two bikes the specs are similar.

 

You won't know until you know. Go for it.

Spring rate will need to be addressed. And often a stiffer spring will overwhelm the stock dampening, especially rebound.

Stock GSX-S rear spring: 9.1 kg/mm
Stock VFR800 rear srping: 15.3 kg/mm

Ouch. To make the GSX shock right, you might as well rebuild yours.

 

Hey you may have already addressed this issue, but i have to comment. I had a client come in; discussing rear shock sacked etc on his 98 VFR; and it is his 3rd replacement shock? Do wha~ ? i own and ride that exact same bike; i use to roadrace in WERA etc and have pushed both ends of my bike; to hard lines while in the mountains' etc i am a hefty 220 lb man, that wheelies his VFR quite often etc then sets it in the turn, and bags turns too and some times while two up with my 110 lb son. So how could this be? The Travel trunk . . . look at a porsche GT 3 and its rear wing? those travel trunks; put added leverage & pressure on the rear end of the bike. The faster you go, more of that leveraging force. Jamie Daugherty DMr Motorsports (260) 710-4049 or jamie@daughterymotorsports.com in Fort Wayne Indiana cured my clients issues. In fact i look forward for Jamie to do two more bikes for me. He states it is better than a Penske shock, and from what & when i rode it, the input was very nice & generous on my clients bike, as we did both ends, rear shock & forks.

 

A high quality shock is always a (the) great answer, you are not wrong there. But these threads pop up every now and then, and the genesis is almost always the same,

"but I cannot justify the cost of a aftermarket replacement"

Most people don't really understand how tailored shocks are to the application. If they did, and experienced a really good one, they might be able to justify it. Suspension is almost always the best money you can spend.

The "shock looks a fairly close match" is most of what they think is important.

The same thing happens all the time with master cylinders and calipers too.
