RC51 Suspension upgrades - March 14, 2013, 09:56 PM


I'm getting my new to me 2003 RC51 tweaked to my liking and am ready to do the suspension before I do some track days. I've done one TD way back when on my 929RR and have been riding bikes all my life.

I am a big guy - 6'4" 285lbs. So I know I at least need replace the springs. I have been getting information from some of my friends (some on here) but would like to get any other advise before I spend money one way or the other.

It looks like I would be better off biting the bullet and just buying a new rear shock instead of trying to respring/valve the stock one (if that is even possible). I'm looking at 3 options:

Ohlins HO204 from Kyle racing for $945

Penske 8993 $825

JRI double adjustable $985

All sprung for my weight at the prices shown.

Forks I am thinking just springs and a valve job. I haven't priced this as I'm not sure what my best options are.

I plan on doing several track days a year on this bike as well as ride on the street. Thanks for any and all feedback.

Redlevel is full of great advice, and he even answered questions for me and drt_jumper when we were in the middle of installing my racetech shit on my V-Strom

Be honest with yourself. If you're just going to do track days and don't have any plans on following a racing path I would just get the race tech valves and do a re-valve and spring on your stock shock and forks. The stock stuff with race tech internals will be awesome compared to stock and probably more than you will ever need or outride. I know the RC pretty well and the forks have a super long top out spring which SUCKS so I would replace that as well so your pre=load adjusters for your forks would actually do something.

You could get all the racetech goodies plus springs, seals, bushings, and oil for what you would pay for the ohlins shock alone. Then you will just pay labor to have it all installed $300-$400 depending on if you bring the complete bike or just the suspension and you'll be riding on some very capable stuff.

Of course I wouldn't blame you if you went the after-market shock route as they are all really nice and adjustable units and if money is no issue I say GO FOR IT! But if you are not running advance group times and just want to enjoy some TDs and street riding I highly recommend the racetech stuff in the shock and forks. Let me know and I can get you an exact quote OTD.
