Okay guys, I need your help. I'm looking for a custom frame/chassis builder that will build me a strong, lightweight, gusseted, long travel, chromoly Banshee Frame that I designed on a old Auto CAD Program I had back when I was in college for a recreational race/play/trail Banshee.

 

I called, emailed, and talked to Tim at Stellar and the guys at Viking Powersport's and both say its to much for them to take on because they would need a Banshee and a 2009+ Yamaha YFZ-450R/X present to get measurements off of as they go to insure the geometry is correct.

 

This Banshee/YFZ-450R Hybrid Frame accommodates stock or after market 2009+ YFZ-450R A-Arms, Shocks, Spindles, Hubs, Front Brakes, Steering Stem/Flag, Foot Pegs, Front Bumper, Aluminum Sub-Frame, and Rear Grab Bar and it uses stock or aftermarket Yamaha Banshee Motor, Radiator, Plastic, Heel Guards, Gas Tank, Seat, Air Box, Headlights, Rear Shock Linkage, Rear Shock, Swingarm, and Rear Brakes. I know what a lot of you guys are thinking.... Why not do a Banshee motor transplant on a YFZR Frame???? I like the way the Banshee looks, plus I'm having a big 500+ cc motor being built as we speak that should produce torque numbers in 70's at the rear tires and I'll need a +6 heavy duty arched latter swingarm to help keep the tires planted and the nose down. The Banshee has a assortment of different lengths and style swingarms available and the YFZR doesn't.

 

I plan on running a Stellar Banshee +6 Heavy Duty Arched Latter Swingarm, Elka Banshee Long Travel Rear Shock Linkage, Dual Rate Fox Podium Rear Shock (11.5" Rear Travel), YFZR Fox Float Evol-X Front Shocks , YFZR Houser A-Arms, and a Houser +3 YFZR Steering Stem with this long travel frame and the total wet weight even with the +6 swingarm should be reduced somewhere between 18 to 21lbs if my math is correct.

 

Please let me know if you know of a chassis or suspension build that might be able to help me out with this.

 

Thanks

Jim, I am all for cool new stuff, but you're trying to reinvent the wheel.

 

There's literally no reason to combine parts from these two bikes to build one.

 

You can use an OEM chassis and have the work done.

 

I shed a lot of weight off mine just by redoing the front end. It rides and handles good and I had minimal expenses in doing it.

 

You're not going to find any chassis builder willing to attempt this without every single part in their shop and the price is going to be astronomical.

Your probably right Tyler. I wanted to go that rout because aftermarket YFZR and Banshee parts are readily available and easy to upgrade down the road. I see your point, maybe I can get somebody to mod a stock frame for me.

Any chassis builder can mod a stock frame that uses OEM parts. I think that would be your best bet.

It seems like you may be trying to reinvent the wheel. However, I feel there are a few parts of that design that may be worth keeping. At first glance it seems as though the 450 rear sub frame is nonsense, but that allows you to run the 450 style seat which I would love to see. Also I do like the fact that you want it to be able to just accept 450 front end components. That makes parts availability greater. One of the bigger issues with the LSR and Laegers frames.

 

Basically I think you would be better off having a stock frame cradle section to build off of. Maybe some guys think different, I guess it would just depend on if the builder wants an existing cradle section or start from scratch. The banshee market is due for a readily available long travel frame. After seeing the stuff coming out of Turbo Chassis ( stock look alike ) I think you might be better off trying to work it out with Jordan. If he could make a modern frame that takes 450 components and rear subframe and seat sections, for under 4k, that fucker would never see the light of day. Best part, whoever does it that way doesn't need to build everything from scratch which makes it faster turn around and cost less. Plus guys like Jordan or Chris at Wheelman already have everything off the cradle jigged up. Good luck and post the results. This is one of your better ideas..... Needs some tweaking, but it's a solid start.
