FireHead Posted March 28, 2007 Report Share Posted March 28, 2007 Like the title of the thread states, how does a person go about figuring out what length of swingarm is best for a given application? What are the advantages and disadvantages of the different style of construction, and different materials? What are the advantages of having a link vs. no link arm? Is you swing arm choice effected by the type of shocks you are going to use? I am trying to figure out the swing arm length I need for my triple and it's frame. I am not really sure how to shoose a good set of paddle tires to start with. From there on I think I can make an engineering case for several lengths of swingarms. So, I'd like to see how everyone else chooses their swingarms. Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted March 28, 2007 Report Share Posted March 28, 2007 buy one of each length and start at stock and move up until you cant lift the front wheels then go back one you going to be hillshooting your tripple or drag strip? i know the no link runs ery well on groomed track but not too sure how well they holdup on somethink olds where the whopps get bad mid season...

Crazy05 Posted March 28, 2007 Report Share Posted March 28, 2007 (edited) I ended up with a +6. I wouldnt want any more for the dunes. Its a handful to turn but I can. Since I also want to hill shoot I started adding power till I feel I'm maxing out the +6. I am currently using 22x11x8 9p with 6lbs air and they make it even harder to turn but it works great on the hill. I'm makeing 70+ ponies to the wheels. Hope this helps Edited March 28, 2007 by Crazy05 Quote Link to comment Share on other sites More sharing options...

I going to be doing both hill shooting and sand drag racing. Probably a great deal more hill shooting. I am sort of leaning towards a linkage style arm, but I would like to hear some other opinions about it so that I can feel better about my decision. :geek: Quote Link to comment Share on other sites More sharing options...

My red bike puts 72hp down to the rear wheels and I am well within the operating limits of my +4" arm. If I were just duning I wouldn't put anything more than a +4" arm on my bike. However, my triple is probably going to be putting out closer to 180hp at the rear wheels. So. now you can kind of see where my personal experience gap is. :thumbsup: Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted March 28, 2007 Report Share Posted March 28, 2007 yea i cant help you much with the no link style i havent ran any... you got any idea of what kinda hp your looking at? and what frame? Quote Link to comment Share on other sites More sharing options...
Crazy05 Posted March 28, 2007 Report Share Posted March 28, 2007 Trips rip. I would think at least a +12, +14 with 14p and hold on. On the flat drags much shorter with a bar. Quote Link to comment Share on other sites More sharing options...

I have pretty much no experience with a wheelie bar..........................I have no idea what to do once you throw that in there. I know you're right, but how to put a number on the arm legth I need is tough. Quote Link to comment Share on other sites More sharing options...

FireHead Posted March 28, 2007 Author Report Share Posted March 28, 2007 180 hp???!!!! Go longer. Sounds like you need to take a ride over to PS for that bad mofo. I don't like Planet Sand very much. The population over there is mostly a bunch of folks with too much money, that don't work on their own stuff, and pretty much talk out their asses. There are a few good industry folks over there, but you have to listen to 10 people, who have trouble getting out of bed in the morning without getting hit by a truck, tell you about something they heard about once, that some other guy saw. :shoothead: Quote Link to comment Share on other sites More sharing options...
Crazy05 Posted March 28, 2007 Report Share Posted March 28, 2007 They dont care for duners as much but they are very helpful. They helped me out a lot. Just be patient and persistant. Now that your moving up to the big time they will probably much more receptive. I think if you wnat to get top of the line stuff they are mostly saying GT performance I think. He builds nice swingers that are designed to put the power down. I'll go see if I can get a link. Quote Link to comment Share on other sites More sharing options...
Crazy05 Posted March 28, 2007 Report Share Posted March 28, 2007 GT Performance I would also call around some other places too like K&T A&S Ohton and whoever else you can think of. Quote Link to comment Share on other sites More sharing options...
FireHead Posted March 28, 2007 Author Report Share Posted March 28, 2007 GT Performance I would also call around some other places too like K&T A&S Ohton and whoever else you can think of. GT definitely does good work. Before I start shopping for an arm by vendor, I would just assume get a better idea of what I need. I have recieved alot of reccomendations so far, but they seem to be all over the place and no one has really been able to back up the reccomendations with a technical explanation.
