That looks awesome.

looks way better than the front end you had before
how do you like the riding position now though?

and how much higher has the seat gone up?
or did it come down?

what size wheels are you using now?

& how'd you get the speedo & tac to work?

That is really cool looking! Nice. May I ask (I've meant to for some time) exactly why they've started turning the forks upside down? I can't picture how rightside up or upside down would change anything. I mean, it compresses, then it decompresses. Is it just a cosmetic thing? Something to do different on bikes that otherwise always look the same?

Please enlighten me!

Don't get me wrong, I like the look, but....

USD forks are stiffer offering less flex or movement in the most extreme riding conditions. For most street applications it doesn't make much difference but on the race track it can make a huge difference.

They can also be a nice upgrade because most USD units are adjustable cartridge forks and should perform better than right side up damping rod forks.

It also looks cool as hell.

I sort of figured it was gonna be some extreme race track thing originally. I'm thinking of doing it, but it takes me a long time to make a final decision. In the meantime, today I ordered Progressive springs and a Holeshot fork brace. What the heck, right? Maybe that'll be enough for me.

Looks great. I really like what you did with that fender.

But, the big question is, how does it feel?

gsxr400 racer · « **Reply #8 on:** February 13, 2006, 11:33:18 PM »

I will try to answet everyones questions.

Cruz- No the ride hight did not change and the riding position is alot more agressive. But gsxr400racer can tell you all about that. As far as the wheel size it is still a 17 so there is no difference. The tire size has chaged from a 110 to a 120 makes the bike feel a bit lazy. But it compensates in more than enough to not make it an issue.. The speedo- I an using a cateye astrale 8 which is the one of two bicycle speedos that will work. I will use the stock as soon as I have a longer cable made to fit the rear wheel.

Gsxr400racer- Yes the brakes are a bit over the top. All I hava to do is think of stoping and it comes to a hault. As far as the rear tire. I am in the prosses of looking for a sv 650 swing arm that will fit a 160 tire. Or even a single sided swing arm if I can find one that will fit.

PitterB4- I have to tell you that it handles like a dream. The bike feels like its glued to the ground and there is nothing I can do wrong. My confidence is up by 1000%

Lowkey- The triple tree conversion was pretty staight . I swaped the stems and it worked pretty straight up. Sorry I have no photos. I get cought up in the moment and I forget to take photos. I am also a painter ( murals ) and I can't explain how it happens I just know it does.

Desolation agel.- Your question threw me for a loop. I Can only guess that its because the USD forks allow for a wider, longer, harder spring to fit without interuption from the triple clamp. Making the bike more stable. I will do the resurch and get back to you on this. However I just like the way it looks. I just looks pretty damn cool.

WOW! so what kind of "CUSTOM FABRICATIONS" did you have to do or was it basically a direct fit? I've been thinking about doing a '93 front end conversion but this looks so much nicer.

SV good show stay away from the single sided deal ! cheers and happy motoring,( sv wheel will fit in that swinger

Better brakes, better handling, better looks - VERY nice mod.

Are you certain that the sv wheel will fit the stock swingarm with no mods? I was afraid that it would not line up.
