The Desmo is a MOTOGP bike that is street legal and detuned. The busa is Not anywhere CLOSE in the same league as the Desmo. On board mgmt system, adjustable traction control, the BEST Top of the line Ohlins suspension that money can buy, Full Brembo braking system, almost 150+ lbs lighter than Busa.....List goes on
On a roadcourse, don't even bother taking the Busa outta the trailer. Most, if not all, literbikes will lose as well.
Drag strip, could be a different story....but...I believe the Desmo has launch control, so you can pin the throttle, feed the clutch, and full throttle clutchless upshifts without any worries of wheelies. But that's with a competent rider who knows what the hell they're doing.
$72,000 price tag? That's just to own the bike. Dont forget about what happens when the bike breaks down. Parts alone will cost way more than the Busa MSRP. Not to mention, there is a specific Bridgestone 200 rear that's in race profile that you have to buy to fit the Desmo. To my knowledge, no other tire manufacturer makes a rear size/profile to fit the Desmo's rear carbon fiber wheel.
Raydog sums it up best......It's like owning a Dodge Viper and asking to race an F1 car. Apples and Oranges?
