CENTRAL POINT, Ore.-X-Treme Indoor Enduro will take over the Jackson County Expo this weekend, put on by Oregon Motorcycle Adventures (OMA)-KTM.

For those who are not familiar the sport, the promoter of this weekend's event, Jeff Moffet, described it in a few words. "We take the woods and we move it indoors," said Moffet.

Usually done outdoors, it was not very convenient for spectators, so crushed granite, boulders, rocks, and two truck loads of logs were used to put together this course.

Dirt bike riders from all over the nation are set to go through it this weekend. "We got experts, amateurs, women and trials tonight and they will be competing for the main events tomorrow night." said Moffet.

One of the course's highlights this year is an 18-foot wooden rail wall. "It has really three types of angles and the center is at about 70 degrees on a vertical slope and the guys have got to have momentum and they have to be consistent in their speed to create a force that will carry them around this vertical wall and down the other side," said track designer and builder, Vernon Crabtree.

The riders will also go through tunnels, jump over tires, cement and cross boulder, rock and wood pits--all requiring a lot of strength--according to X Games silver medalist, Louise Forsley. "This is such a physically demanding sport and it takes a lot of strength because you're constantly picking up your bike and maneuvering it and it just takes a lot to get over the obstacles at a race speed," said Forsley.

Devin Watson grew up in Medford and just made the switch from motocross to endurocross, so he does not think he ranks at the top, just yet. "In endurocross, probably at the bottom, but gotta start somewhere," said Watson.

The dangers of riding and a family tragedy had the father of this seventh-in-the-pro-series rider worried, giving him a late start at 18. "He was kinda a little sensitive about it. He lost his brother in a race, like racing street bikes, so that kind of had a little bit to do with it," said last year's x-Treme Indoor Enduro second place winner, Kyle Redmond.

First place at this event last year, went to Cody Webb, who ranks second in the nation. "This year, a lot more riders know about it. It's becoming like a pretty predominant event here in the Northwest, so uh, I came back [...] It should be a good race tomorrow," said Webb.

Tickets for Friday night's qualifiers are $12 and $18 for tomorrow's main event. Two-day passes are also available for $24. Kids six and under get in free.

A new 2012 150cc KTM dirt bike will be raffled during tomorrow's main event.
