A fellow club member, Joey Giordano, was a factory team racer for Christini.

I understand the company faced serious financial difficulties.

I'd wonder at the business plan's marketing strategy; who will pay the price for the modification?

From the website:
Quote:
The MSRP for the KTM kit is $4595 and the Honda kit is $3995.
Does the targeted market segment (whatever it might comprise) have the means to afford the Christini kit?

Are KLR riders potential Christini customers (were a kit available)? If so, how much would they pay for the privilege of all-wheel drive (the system is NOT, "two-wheel drive," power to the front wheel is only available upon "demand," slippage of the rear wheel).

Couple of things come to mind. Additional weight? How much horsepower will it "rob" versus the benefit? Torque steer? Have heard of it but never thought it through. What is the input of the riders that have tried it?

Gray-haired riders donít get that way from pure luck.

Ain't ridden it myself, only talked about the experience with Joey, who enjoyed some racing success with the machine.

Not a great deal of added weight, just a few pounds, from the pictures of the kit on the website.

No hosepower "robbed," 'til the rear wheel spins. Up to that point, the front wheel free-wheels, as in a normal motorcycle drivetrain. When the rear wheel spins, traction's more important than horsepower, I should think.

No speaka "torque-steer" on a motorcycle; gyroscopic moments, precession, etc., should be unchanged between AWD/one-wheel-drive, seems to me; Joey never mentioned it.

Again, never rode one myself.

Complicated system. The idea is good but thats a lot of gears and sprockets and chains to maintain/replace.

I'd ride one given the chance.

The twin drive shafts counter rotate so ya, there should be no torque steer.

+ 1; BTW, Christini isn't the first/only motorcycle powering both front and rear wheels; q.v., Rokon!

OK torque steer may have been the wrong term to use to describe what I was thinking. I was thinking about the front wheel pulling you in a direction you may not want to go, say leaned into a turn under power where normally the rear wheel would be kicked out and spinning...drifting.

Convinced the condition you conjecture presents no practical operational problem, are you willing to pay $4595 for an AWD kit?

Raced successfully in highly-competitive off-road events, handling seems at least manageable, if not superior to one-wheel drive systems, in some environments.

Overshelmingly dominant? Probably not; the RIDER's skill still plays a role, but--given the variation in riding styles and riding environments, AWD may have its niche.
