Is it possible

a different swing arm and put that same big belt that's on the boss hoss that should work?
 
How well do Hoggs corner? - I have no idea.

I know that I'll catch some Hell for stating this (again), but it has to be said.

The Boss Hoss is for riders that are either trying to compensate for lack of penis size or who enjoy bragging rights for owning an impressive 'Main Street Cruiser' ("Look at me!") that doesn't do much else very well or practically as an everyday motorcycle, and that's about it. It's a two-wheeled equivalent to a weightlifter with (ste)roid rage. The only thing it really does superbly well is melt its own tires on demand and look pretty ( to some) standing still or gliding on by.

Considering the size motors they sport (GM 350s or 502s), they deliver (comparatively, for their size) very little usable power to the ground, especially when contrasted with virtually any R3 (from a DIY filter/retune job right on up to a fully kitted Silverback) or with most other "normal" motorcycles, for that matter.

They are unwieldy to ride, park or handle in general and they run hotter than Hell. (BIG powerplants). Most every Boss Hoss owner/rider I've ever met has been an obnoxious, attention hound - Oh, alright, truth is, every Boss Hoss owner that I have met personally (over a dozen) fits that description. That said, I am sure that there are some great guys and gals out in the world somewhere who do not fit the profile I describe.

There, I said it and I said it with no offense or malice intended toward anyone. I understand why some people would like to own one ["Because (as Sir Edmund Hillary's climbing partner, George Mallory once stated) it's there..."], but I wouldn't have one if it were given to me, simply because, other than for its sheer, shock value and mass, I could never have any practical use for such a thing.

And, "yes", I have ridden a Boss Hoss. One hour of riding that thing was enough for me to see the light.

Go with the Boss... there's no replacement for displacement,... however, the Triumph Rocket III is still the overall King of Bikes

I'll delete this slightly corrected post of yours if you truly disagree, scot in exile.
 
Hey All,

I have this Kopavi Trike, some videos out on my youtube channel jrtube47 as well. I bought this beast back in 2012, its a production vehicle, Marvin Beckman (building V-8 trikes for 40 years) out of Mena, Arkansas, can be customized. Mine has TPI 350 with 700R4 trans, ford 9" pumpkin with 3.0 gears, 4-link suspension, really fast, 0-60 less than 3 seconds, 0-120 in less than 6 seconds, can hang with just about anything on the road in a straight line. I really enjoy this bike. Have owned a lot of 2 wheelers, 25 or so, wanted something unique, researched V-8 trikes for 3 years, came across Kopavi and it was lust at first sight, test drive sealed the deal. I set it up for more touring than straight up dragster but the nature of the beast loves to go fast. Marvin fitted one with a 572, 800 HP or so monster. I tow a trailer when I tour, 2K RPM running 75 MPH, hitting 21 MPG, but I didn't buy it for fuel efficiency.

Now, as a custom vehicle, hot rod type, comes with all the typical hot rod issues, you have to wrench on it yourself when quirky problems pop up, 350's and 700R4's are not known for their tight seams, you get seepage of fluids, hard to keep undercarriage clean. Coil over shocks, one started leaking, had to pull off and ship back to manufacturer for repair, same happened with fork seal, I have to pull tires off and carry up to bike shop for replacements, have to keep injectors clean, I do the oil changes myself, horn ckt went out, had to re-wire horn, pop a fuse, have to pull valve cover off to get t it, cleaning/polishing takes a couple hours or so.

Speaking to engine heat, hardly any, ceramic coated headers, no heat shield required, I ride with flip flops and shorts sometimes. Radiator in the back pulls heat away effectively. Contrast to a boss hoss with radiator in front, when fans kick on and your sitting in summer traffic, sweat your balls off.

For riding experience, nothing like a bike or car, very unique ride. But that's what I wanted something very unique. Mine is #18 out of 18 for this model, also first one with TPI, dyno tuned.

Boss Hoss has been building bikes for a long time, they are fairly good at it, but I would consider them a custom vehicle/hot rod with all that comes with that type of bike. For convenience it's good to have a shop or mechanic friend to help keep bike in shape.

I really enjoy my R3R as well, fast, tight, rides like a proper motorcycle, wouldn't change a thing except add more power, maybe a carpenter kit some day. I can't see changing chassis, raking forks or extending swingarm, will change ride dynamics and create a Frankenstein. If you want a different ride/vehicle get one that is purpose built for what you are wanting. IMHO you should have more than one bike, so if you crash one, you still have another to ride.
