Police are reminding motorcyclists they are not "bullet proof" after a crackdown revealed the extent of dangerous driving on Canterbury's highways.
Speeds of 120kmh and over were the norm on State Highway 1 and SH75 and dangerous driving was "far too common", said Canterbury highway patrol Senior Sergeant Neville Hyland.
A higher than usual number of infringements had been issued during the crack-down, with offences including speeding, dangerous overtaking, and breaching licence conditions.
In an incident this afternoon, a speeding motorcyclist had his bike confiscated after he was twice stopped by police within half an hour.
The man was initially caught speeding at 141kmh and had his licence suspended for 28 days.
He was again stopped a short distance away and his motorcycle impounded, and was charged with driving while suspended.
"Unfortunately there is a section of the motorcycling fraternity who see themselves as bullet proof and are prepared to take unnecessary risks which all too often are claiming their lives, and putting other road users at risk," Mr Hyland said.
Police are urging motorcyclists to act responsibly and within the law as the weather improves and more take to the roads.
Two motorcyclists have died on Canterbury roads this year, after seven riders and two pillion passengers were killed in 2008.
