TUPELO - Joanne Sanders keeps her cell phone in her lap when riding down Gloster these days just in case she gets a glimpse of two-wheeled bandits using the streets as their own personal stunt grounds.

Sanders said she and other drivers are fed up with motorcycle riders zooming up and down the roads, popping wheelies and endangering their lives and the lives of others.

She has called the police several times but before officers can respond, the speed machines are long gone.

"I see those fast bikes all the time, those crotch-rockets zooming up and down the streets, riding on one tire and just being reckless," said Sanders.

"I'm afraid someone is going to hit one of them and someone will get hurt or killed."

Crotch-rockets are motorcycles that are of the street-bike nature, which are built for speed.

During the summer months, motorcyclists hit the streets in force.

For most bikers, cruising with the hot summer sun on their backs is what it's all about but a need for speed fuels others and it's those who police want to concentrate on.

Tupelo Police Maj. Anthony Hill said because of several complaints the department has gotten over the past couple of weeks, they will crack down on illegal and dangerous motorcycle activity.

"Concerns about motorcycles have been increased, so enforcement has to be increased as well," said Hill. "We want everyone to be safe and that includes those riding motorcycles. And if people are speeding, weaving in and out of traffic and riding on one wheel, then they aren't being safe."

Hill said people in residential areas have complained about motorcycle's roaring pipes.

He said there is a noise ordinance and if someone is caught unnecessarily making noise on one of the machines, they could receive a ticket.
