Shock options
So I think I will be upgrading my shock this off season, and would like to get some opinions from those of you who have upgraded your shocks.
To be honest I don't find the stock shock to be that bad. According to Race Tech web site the spring fits my weight (195lbs). It just seems to fade a little as the race goes on. More important I would like something that gives me ride height adjustment without messing with the dog bones. I would like to lift it about 5mm. The shocks I know about are the Ohlins, Penske, JRI, and Elka. IMO the Ohlins is the nicest of the bunch, but at $1000+ it may be a bit overkill for the 250. I have a friend who has rebuilt some of the Elkas and has had some trouble with getting them to work right after rebuilds. I happened to talk to someone who was running the JRI and he had some issues with it leaking. So with all that said, I'm not sure which way to go. Thanks in advance for any input. Doug |

http://sportisimotorsport.us/index.p...products_id=29 http://sportisimotorsport.us/index.p...&products_id=9 Or a 06 GSXR 600 shock install, which is what I did. I have about 30 bucks and an hour and 15 minutes of my time to install, but I got the shock free and had two friends helping with install...

You can get an Ohlins for $7-800 brand new and built for your weight from a number of online retailers. You may have to call them to get the discount, but I certainly didn't pay $1000+ for mine. It does offer ride height adjustment and, best of all, is legal for the series that don't allow you to modify stock dogbones (Don't know about the series you race in, but AFM in california at least doesn't allow it).
Still pricey, but I feel like it's the best money I've spent on my bike thus far, personally. I can't speak for other brands though, as this is all I've tried |

At this time I'm leaning toward the JRI or the Elka, but still open to other options. |

The Nitron shock looks very promising, and the one I will most likely go with. There may be a group buy opportunity if anyone is interested. I may post this up in the market place for a group buy.

Nitron does not make a triple for the 250

I have gone for the GSXR option, at least for now. Yes the dog-bones are not stock to get the height right... haven't figures out a better way of making it the right height. Unfortunately the stock mounting options where you can add spacers does not fit the 250.
JRi and Elka sound interesting, there is also a Penske option as well. I'm keeping an eye out for a better setup, but budget is a major constraint at this time, though I tend to through money at things if I feel they hinder lap times |

http://www.mcmaster.com/#91180a723/=p6cnw4 Will also need a half inch spacer on either side of the dog bone. I was thinking of having some new dog bones made to bring the rear back up to stock height, will let you know if I make multiple sets.

I got a "kit" with all new hardware and linkage. You also have to enlarge the bottom end of the shock to 12mm.

I ran a Penske double with a variable bleed piston (same as most AMA teams) and loved it. My rear tire looked like a motogp tire after a race with it set up correctly. and with the adjustable shock length I was able to change the geometry and swing arm angle which honestly helped the bike more than anything. www.tracksidesuspension.com is who I had build mine. Also im confident the stock spring is WAY to soft for anyone over 130 lbs

I'm doing the GSXR shock conversion, widened and drilled out the lower mount to fit, but not sure if I should also drill out the upper mounting hole, stock bolt is a bit larger than GSXR.

I would have to imagine something like a Penske or similar where you can modify the shock with new mounts to change it up for a different bike would be the only way I could even begin to justify a $1k shock for a $4k (brand new) bike.
But then again I am really slow lol |

High end shocks hold value well, so you can sell it with the bike or separately in case you want to try a different platform. |

Ironically, the shock for the 250 does not transfer well.

What do you have the ride height set at on your rear shock?

I'll have to check, it's not in my notes. I'll try to get an eye to eye measurement for you. It's damn cold here to not have a heated garage...
