Hackstetter

all i hear about these days is "theft" some people are just scum

I'm starting a line of entry level 125cc all wheel drive street motorcycles(concept shown above) based on the design of our first build  Read about our first AWD motorcycle, i hope it has a future with new riders?

A few years ago I built a prototype 2x2 if anyone wants to read about it, here is the articlehttp://www.fasterandfaster.net/2013/03/rob-hackstetter-talks-about-awd-invex998.html

i used google sketch a free and basic program for making 3d anything, a good starter program if you wanna try drawing in 3d i think http://sketchup.google.com/
and the best part; it's free!

AWD front end

this any help

If i could find this in a 12v power supply like an N20 Bottle heater this would work.

Thanks Guys

was thinking of a "stove pipe" off the header and then i thought about years later when the bikes are old it would just be a good way to set the bike on fire

ive had no probs riding at -10 in the uk running standard 10w/40

I may need nothing, however I see it as a preventive measure. few bikes use gear oil, I think BMW uses it in the shaft drive (ring and pinion setup) I use gear oil in my gearbox because I have a gearbox similar to a transfer case for the 2x2 and I do not want the thick oil at first start to hinder the torque biasing of the all wheel drive.
i might be able to switch to an ATF type fluid

winter in Finland, i was thinking of running a coil/exchanger that has hot radiator fluid pumped into it

yup 10 Celsius 80/90 weight gear oil... i'm looking for a method that does not require a power source not on the bike?

bounce off some ideas to some fellow "motorheads": i'm going to do some enduro type testing on a police interceptor concept that has 2x2 borrowed from my invex998 that i've built. Temp outside will be on average 14 degrees, my transmission has gear oil in it and i'm worried the viscosity will not react well in the cold , especially from a cold start, this may effect the 2x2 in the first 10 min of use.
I was thinking,could i preheat the oil using exhaust temp/ exchanger, or engine coolant or something electric.. has anyone ever seen anything like a pre heater on a bike?

very sad to hear, let alone see. Life seems to be so cruel and unfair. I will say a prayer for the mans family

other then some radical engineering. Your right not much of a point with this bike

What's the point

for the time it did well because it was pulling around the track.. keep in mind tires "sucked" in 1930'ish and i guess putting the weight of the motor low made it's CG much better than bikes of its time

The point is? An american GI took it home after the war and it was lost

i think the fuel is fed into the axle like the banjo bolt on a brake line....crazy stuff

front wheel drive, the engine is in the hub!!!

how much horse power that is some machine

seems they sourced a car hybrid electric motor, and the voltage is like (430 volts 1200 amps

hey Folks,
Maybe since i've been so busy i haven't had much time to look at what others have done with prototype bikes

you gotta respect Chip yates.. he went racing with his dream and kicked some ass

got me thinking about a Hackstetter AWD electric with a Dual KERS system?

I was at 175 with a Yamaha engine, but since I'm going to offer bikes I had to get a license agreement and only one company I found was offering running gear under license so I'm using a new/reworked Kawasaki engine

998 cc making 200hp for 2012, the front wheel is always engaged, but the torque biasing is always active and adjusted front and back in 1/10th of a millisecond

mostly you hear about all wheel drive in cars, but one thing that alot of people forget is when you sit in the middle of a 50/50 weight distrubution and a 50/50 split of torque transfer some amazing things happen. For me; All wheel drive in a motorcycle makes more sense then in a car
But im sure i'm biased

na from what I can gather nowt like I thought the same.
Its very clever design more so than that I recon. Dunno about the advantages though.
It must suck a few BHP out the motor.

A 3rd party study (not my own data)used my bike in testing and some surprising things came up, 5 percent faster around a track rain or dry, which I love which I must say I wanted to hear!
Now 20 percent less throttle angle for the same achievement of a rear wheel drive bike, and the theory is no wasted torque transfer coupled with minimal travel in the suspension. Fuel economy went up? " I was like what the F@#K" some unexpected even controversial good news!!! We even had to model the data to make sure it was honest..
we learned a few things that day/ the other side of differentiation/ Engine braking using both wheels when slowing or down hill.. all these things collectively become one big advantage.

"future" if I can do a carbon fiber frame and wheels ,then I can keep my weight under a current 2011 one liter production bike and maybe a direct cylinder injection system and fuel mileage would be grand

finding a class to race in will be challenging, need to slip into an open ruled body of racing if possible.
I do see this as the perfect street motorcycle benefits on poor roads, rain ,and sand etc...This particular bike will not wheelie. because the front is pulling just as hard as the back is pushing , as a side affect even my suspension travel is reduced . But in the event the wheel(s) come off the ground.. the driveline has what we call "percent locking" of the applied torque.. so it does what a normal bike would do if the lifted wheel is slower then it's contact, the tire takes the friction with a"puff of smoke" when it meets the surface at a different speed

Hi Can you tell us any spec or would you have to kill us The front wheel drive must be hydrolic powerd via a pump?drive from where?Most interesting
Did you build the frame,

Ha ha,
I did consider making the drive hydrostatic but found a few major issues. A superbike can do 180mph, the pump and hydrostatic engine to drive would be rather large and heavy? about 85lbs of gear, plus fluid drive is typically a set ratio like 1 to 1, no differentiation. A Nitrogen accumulator would be needed for wide open throttle. I messed around with hydraulics and the parts to make it work started to get rather big
again after careful consideration I chose a mechanical design/setup, my frame has a "Porsche like" torque tube similar to the unit in a transaxle only smaller. power is split front to rear, and balanced in the headtube to eliminate torque steer and transferred down each side of the wheel to counter balance, eliminating torque steer in the front wheel.
The detailed method is now a US patent

thanks!
Those lions came from my Fathers family flag Baden/wurttemberg Germany

Thanks To Dave Hutch for putting this forum together and the invite! Also I thoroughly enjoy each members posts. I'm sure this bike is not everyone's cup of tea. But hey deep down inside I'm a minimalist and it even goes against my grain, I like the "Naked" bikes but admittedly I'm also obsessed with progressive technology. I know a few 2x2's came and went but I wanted to shake the motorcycle world with a NEW SUPERBIKE and make what one tech editor said was the Audi Quattro of motorcycles
