swingarm extensions

are they worth anything?? or should i just save my money and get a whole swingarm?? im only wanting a 4in extension but i am still worried they might snap and send me and my busa to the ground. i have seen them around quite a bit tho. i dont have that much power. bike is stock except pipe, k&n, and pcm. and who makes the best swingarms??

Well let me see..........the reason for a swingarm extension is really for racing purposes. If your not wanting it for that reason, there are plenty of web sites/companies out there that deal with swingarm extensions. On my bike I have a 6" to 8" adjustable. :drool:

Or get wheelie bars so they can be taken off when you aren't drag racing.

I think the extensions are just a cheap way of doing it. But then again I know nothing about this crap! :D

you just suck! :lol::whistle:

im just curious to someone who has used them. i would rather spend 300 on extensions and a chain than 2500 on a new swingarm. its all for drag and show. but i want somthin that is functional and looks good. im am all about goin straight. not tryin to drag my knees. or at least not that much. im a 1/4 mile guy. or i wouldnt have bought a busa

i was thinkin about leavin 4'' swingarm extensions on all the time and strappin the front when at the strip. good idea or bad????? im just worried about the durability of the extensions. i wouldnt think 4'' with a mostly stock bike wouldnt be that dangerous/risky but i want to make sure b4 i go to the strip and find out different.

Big.... PM spiderman he's the resident 1/4 mile guy!

i have an XX as a few of you know and i have the variable 6- 9 inches, i hear alot of differeant crap to. it depends how extreme you go and how tallented the person is that does the extension. my bike for example has an airtank in the swingarm for an airshifter, and tones of stableizers inside the arm, as well as good welds. i dunno what my arms are rated for proabably around 300. the guy who did it told me 500 HP (though i remain skeptical). Has a nitro busa with around 300 hp, and he claims to have a gixxer 1100 with around 500 hp. so i dunno. personally i will maybe in the future, maybe, shoot for the 300 mark but i will be deffinatly consitering underbraces on it. a company that makes good arms if you want to go buy aftermarket is trac dynamics.
KEEP IN MIND........... when you go off and stretch alot changes, stuff i didnt think about to begin with but became evident dam quick. you will need new brake lines, buy 2 chains, the extensions, a new rear suspension (the stock will not do, i learned the hard way), which also means remove the tail and relocate the plate.

do not go cheep.............. i have seen some real hack jobs for a better choise of words, and by hack jobs i mean a busa with 2 heavy bolts holding on the extensions on the arms. NEVER DO THAT.


i have a buddy with a lightning busa, who had his bike break in half on the highway, so make sure if you get it done by someone they know what they are doing.


hope i was of some help.

I have never used extensions but, I would have to agree not to use the cheap bolt on crap. They look bad and you know there not as safe.

its scary cuz ppl call pro welded extensions unsafe, (which they are as long as your not running huge power) imagin a bike with 2 big bolts holding it on. hahahah the first time i saw that i looked similar to this :yikes:

They are common around here with the budget wana be street racers.:crazy:

The only way those extensions will work safely is if they are tig welded to swingarm and thats it. Any other way something will happen.:luck:

yea and that is exactly what i had done tig welding. and further more i had stablizers and all sorts of other strenghters put inside the arms and around them to make em stronger. BTW is that you gixxer in your avatar?? if so thats a bomb ass bike, i saw it featured in SSB a few months back, i like it alot.

:sorry: That bike is not mine. The owner is from Wareham MA. His name is Owen and he owns a company called Competive Edge. What you did to your x-tension's you should be fine. My bike dosent have that much chome but has a much better paint scheme. As soon as I am done with the final touches, I will post my ride.:dthumb: See to me a lot af chome weighs a bike down. My bike is made for the track and 1/4 mile.:crazy:

thats why i love polishing............ lots of shine and show, and techinically less weight (though its like 1000000 of a puond).

You are so right. Why would you add a heavier steel to something that ia a alloy like aluminum? Although it comes down to about a few onces, you do a whole bike you are looking to a couple of pounds. Polishing gives it the same shine but you do have to keep on it more. But there is a product that you can put on your polished goods that will keep the shine for 2 years gaurenteed. It's called ZOOP SEAL.:dthumb:

not getting off topic i use mothers alum, and mag. polish and it works great, remove oxidization, and coats it nice.

Easy solution for about the same price u can send your swing arm out and the y will cut and reweld the swing arm to what ever lenght u want u can get the a set lenght of adjsutable and it dont cost any more than teh blocks do im sent out lots of arms and never had a problem

If you guys want polish. Go to any Big Truck chrome shop. You can find some great stuff.

Jeeps... start a thread about some of that good stuff...I'd be interested in something great...for obvious reasons...

Ill stop by the shop and start a list this week just for you. Diamond is one I like for the touch up stuff. Ill let the new thread speak about the other stuff.:dthumb:

No, exactly like that.:cheers: :dthumb:

here is a few places to look up.

www.rnrfabrication.com
www.exoticycle.com
www.yanashiki.com
and i think www.candscustom.com

look in mags like 2wt or superstreetbike, or if you have a custom motorcycle shop they can help you. hope i was of some help.

Not doing it myself but curious why the budget wanna be street racers always have the bolt on style. Know I know. Its defiantly budget.:crazy:

Id just send your arm out to thompsons or c and s and tehy can d oit for you for about 300 hundred i used thompson personally a few times

I really don't think this bike is fat, low or long enough.

that just doesn't seem like it'd be stron enough to support the torque... with out a upper brace of some sort:scratch: :2cents:

I'm sure that would win a lot of shows but why? why? why? it kills me to see things like that.

I like it except for the long fat back. Especially the single sided swing arm. Do it in normal length and height, I would be proud to ride it.

:withstupi 110%

i love show bikes guys dont get me wrong and the swingarm is a piece of art but when you step back and look at it even i said why? i mean who puts a 360 series on anything.

it's only a 600

it's only a 600
That's something else I don't understand. Why guy stretch the 6's when its hardily needed. IMO its all about looks and fitting in with a group.

now that we are on the topic of swingarms and nitro and what not............ i have an NX system with a stock bracket, does anyone else use the stock brackets or do you guys buy the strong billit ones, i have heard of the flimsy factory brackets snapping and bottles getting dragged by the line lol, and im thinking i really dont want this happening so i was wondering what you guys running NOS and NX systems are doing.

If it looks and fills week. It problem is. I wouldn't want a small unguided missile dragging around either.:crazy:

it's only a 600
correct... but the diffrence between weight of a 600 and a 1000 isn't THAT much... and the force exerted down on the swing arm is basicly the weight of the bike + Rider trying to be lifted...

My friends do a lot of Fab work for their offroad trucks and it was just something that caught my eye...

is the swing arm sleved at all? or just butt welded?:scratch:

Sleeved it should be supper strong.:dthumb: Butt weld.:skep:

Sleeved it should be supper strong.:dthumb: Butt weld.:skep:
well it depends on how WELL it's sleved... (length, the fit inside) but yeah Buttweld is really scary... :runaway:
