Hey guys,

Just tossing around the idea of stretching the busa. However, I don't want to stretch it too far. So what I was thinking was 6". So when I go to order my new swingarm, which length do I get? They are quoted on desired wheelbase. So if I wanted a 6" stretch, would I go for a 64" desired wheelbase? When I look up the stock wheelbase online, it says 58.6", so I just wanna make sure I order the right one.

I am going to be extending the tail section as well at the same time. I will be using this for drag racing if that helps.


Any help would be appreciated. Thanks.

Thanks for the reply frisbee. I'm actually looking at the Thompsons, but also looking at Mcintosh as well.

how much do u weigh?

I have the stock rear suspension that I will tighten up a bit, however I did add soupy's lowering links. I'm 177lbs currently and hoping to shed a bit more for summer to 170lbs.

I'm almost 6 over with a +4" tail section. It makes for a nice looking combination, I think??
I do 2 up riding on back country roads too . NOT terrible in the curves, but I don't think I'm riding a GIXXER 600 either.

If you can swing the price(about $1600 with all the bells and whistles including powdercoating),a McINTOSH Alumipro is top of the line(had a 2"-6" on my '03 turbo bike and can still choke myself for not keeping it when i parted the bike out,that thing was a work of art).:thumbsup:

McIntosh has the Sport Arm out now which is very comparable in price to the evil arms. That's what I went with and I'm very happy with my 6-10 over arm

At what point do you start sacrificing cornering and maneuver ability with an extended arm? I've seen some guys run what they dubbed a "cheater arm" which was only extended 2 inches. Majority of guys I've seen with a turbo/nitrous build run 4-6 inches.

Anybody have experience with a few different lengths and can provide some feedback??

I was +3 on a gen 1 and it actually hooked pretty dam well at 340 rwhp and cornered fine. went to +9 and it spins too much now.

gonna go to +7 in the spring and try that. id say anything over +7 is gonna hurt handling but I don't giv two rats asses about handling. if I did id buy a 600 and take it to the track. cornering on the street is a sure recipe for DEATH with everyone text messaging these days.

I ran a 8-12" Mcintosh alumipro from Goldenchild last year. I had problems with the POS bridgestone tire, so I got a shinko hookup on it and never looked back. I was launching at 6400RPM and hit 9.61 in the 1/4. No performance mods, just the arm. However, if I had more time I would have tried to up the 2 step even further as my front end wasn't even coming off the ground, plus I was just really getting a feel for how the bike reacted and how to control it (first year of racing in a series).

This upcoming year with the new class I'm racing in, I actually have to shorten it, so I will keep my current arm for if I jump up to the ProStreet category next year, but I will only be running a max of 4" (due to rider weight) this year with my new turbo setup.

4" is good . MyThompsons arm is 10 years old with 55000 miles on it and still perfect condition. Something to think about.
