2001 Unknown UnknownFuel systemAcceleration & cruise control

Fuel injection flawed. Motorcycle will surge forward when approaching a stop for no apperant reason. Also the throttle travel is very short making acceleration control very dificult. The local cannondale dealer says this is common on 2001s and cannondale has developed a new fuel injection which cures this for the 2002 models. Standard policy of dirt bike dealers is to not allow test rides as this creates a used bike for them. How is one to know of these problems up front?

1999 Unknown UnknownTransmission & drivetrainAcceleration & cruise control

The throttle failure was more dangerous of the two failures as it occured at freeway speeds in thick fast traffic. These bikes have had about a dozen other nhtsa recalls ket. The throtlle cable breaking was the more dangerous. *Ak

2001 Unknown UnknownTransmission & drivetrainAcceleration & cruise controlCrash1 injury

I personally know 5 men that have bought this machine and 4 of them have this problem. While sitting at an idle the machine will not disengage the automatic transmission causing the machine to roll away. It is defenitely much worse in reverse. The machine will roll up to 5 - 10 miles per hour. The idle has been adjusted down as low as possible without the machine staling. Two of these have been taken back to the dealer and they replaced the clutch assembly but some of the machines are out of warranty and it is...

quite costly to have this done. Polaris should be concerned with safety enough to ask everyone with a problem to bring these machines back so that they can fix this before it runs someone over or even rolls down a hill with no driver and hurting someone that might just be standing there.*Ak

2000 Unknown UnknownAcceleration & cruise controlCrash1 injury

Pull vehicle into garage, stopped. With foot on brake, reached to put car in "park". Sudden acceleration; enough to burn paint off garage floor. The scenario of foot slipping off brake pedal is inadequate to account for damage level and "burn-out" of tires.Photos taken.
