upgrading SV650S forks w/ GSXR forks

Laid down my 2002 SV650S on the right side and did a lot of damage to the plastics. More importantly ,I bent my front forks to the point of no return. Ive been told my many, to not replace w/ stock forks, but to install GSXR750 Forks. And Ive received mixed opinions on whether I should use SRAD forks or pre-SRAD.
Any input on this?
My big question regarding the GSXR forks is
Will I need to replace the whole front end if I use these forks?
What forks can I use that wont require to change anything more than the triple clamp?

Change the whole front end. It's not that much more money and well worth the upgrade. It'll be like a new bike.

I just did a complete 04 GSXR600 front end transplant onto my 01 SV650 (naked). That, in conjunction with a new Penske shock, has totally transformed the bike. You will do just as well with earlier year GSXR front ends as well (and cheaper too). The new ones have radial mounted calipers, but I will be the first to admit that I wanted them more for the bling factor. (Heck, this thing has more stopping power than my 600 track bike now!)

All you will need is a replacement steering stem upper bearing (replacing the one on the GSXR stem), available from the famed Zoran. He is on BARF (as well as svrider.com) as TWF. The bearing pretty much makes it a drop-in opertion. The hardest part is pulling the original outer bearing race from the SV's steering head on the frame, and pressing in the new one.

The primary issue I ran into was replacing the gauges. With a GSXR upper triple, I now had nowhere to mount the stock gauges to. So I replaced them completely with a Veypor unit. Since you have an SVS, you will not have this problem, since your gauges are mounted on a bracket. However, you WILL need to come up with a solution for your speedometer pickup, since it will not mount to the GSXR axle. Fortunately, someone has discovered that it can be mounted onto the rear axle. You just need to splice and extend the pickup wires to reach the rear.

Again, check www.svrider.com for more info. www.socalsvriders.com has a lot of info as well.

It's possible but the GSXR front end is way stiffer. Don't ever hit anything because the forks will transmit all of the impact energy to the frame which can break at the steering stem if overloaded.

at least forks will be good
sv frames are cheaper than stock forks.

I think you're missing the point.

I think the owner of that bike has more to worry about than his gsxr forks cracking his steering stem.

If I rode my bike into something hard enough to break the frame, I wouldn't be worried about breaking the frame, I'd be worried about breaking me.

Unfortunately, the rider died. A 20 year old kid with alcohol on his breath turned his pickup truck in front of the biker at an intersection and they hit head on. The point I'm trying to make is that in this case, the way rigid forks passed all of the impact energy up the line to the frame and the rider without bending. They are very strong, so strong that the frame snapped. Had the stock forks been on there, they would have been more likely to bend and absorb at least some of the impact energy from this situation. That may have changed the outcome a bit. Speed doesn't kill, the sudden stop does.

are you saying that rider may have not died if those forks were stock?
it would still be sudden stop,just different part would breake.it all depends how impact happens.
Sitch broke frame at B-willow.
Felipe broke one at T-hill
another one at willows.
I sold frames to 2 of this guys for $300.
there were all high speed crashes.
and yes,you are right,gsxr forks put more stress on frame in case of crash.
stock forks snap in half and breake motor,and bend frame in some cases.

I've seen those kind of breaks happen with stock forks too, and with just a bike tumbling off a track. Seems like a head-on would be even more force. Don't think you can lay the blame for this on the forks.

On another note, I've heard that GSXR forks outperform the rest of the SV. Although it does feel a lot better there are other possibilities in working with stock forks. However, since you are already needing new forks, you might not want to buy new forks and then pay 2.5 g's for a whole handling upgrade.
