Are the skins aftermarket or from a factory/stock machine?

A few updated pics. Nothing too exciting.

Steering rack mocked up, roof/crossbars done, lower a-arms mocked.

I am hoping to come in around 1400 lb's wet, which is actually a little more than a stock machine. The bigest advantages are strength and handling, both of which will be vastly supperior to a stock machine.(thats the goal anyway.....haha)

Just like with trucks/Jeeps, the factory has to compromise certain attributes to cover a wide range of intended uses, farm work, trail riding, cost etc.

As a reference with regard to handling/suspension. This buggy has 21" of rear travel and will have about 18" front. Compare that to the stock 8-10" and you can see that big air jumps and high speed "BAJA" type riding will be a lot more controlled and safe.

The stock frames need alot of reinforcement , not to mention real roll cage. Some builders go as far as sandblasting the entire stock frame and re-welding /gusseting all the factory joints to ensure strength. I really don't have anything against modifying stock components, but on this build this seemed to be the best option.

Aaron.

Nice use of the dimple die on the steering rack mount. 18-21" of wheel travel on something that size is just insane. That'll make for a fun ride!

Here are a few updates. It sure seems like things are moving slow on this one, but I have been swamped lately.

Front suspension geometry figured out and mounted (less shocks and mounts), steering mocked and mounted, foot controls located:

Nice build, great ideas!

One thought from the pics it looks like you wont get much air flow to your radiator. R U going to duct air in?

CaptAz- you may be right about the radiator. I am eager to see if it gets enought air myself! We really played around alot with different mounting locations, but ulitimatly decided on the location seen for several reasons. If it does run hot, I think we can shroud it and maybe even duct some air if needed.

Crwcompact- I will check out your site.

Thanks for all the replies!

I hope you have some plans to hop up the motor. I have ridden in a rhino with long travel arms and King shocks, but the motor wasnt enough juice to even think about giving the suspension a workout. however, CBR600rr motors fit in there quite nicely.....

The motor you see in the above pictures is not a Rhino motor, it is a 500 cc Polaris engine. It will be used to dial in the chassis and has been used for mock up.

The eventual engine, shown below is a 700CC two stroke Rotax, rated at 125hp. It should move pretty good... :)

nice work, we sell rhinos and the Ag dealership that I work at. Quite impressive units in stock forum, thought about how cool a long travel full caged rhino would be, and here one is lol.
