AX Tour fans should expect some of the best racing of the season for Round 4 on Saturday in Memphis, TN as riders fight for championship points before the extended holiday break.

Heath Harrison is undefeated in the "Cash for Clash" series and has two wins in the AX Pro class while Travis Sewell has yet to lose in the Ax Pro Lites class. Sewell is only nine points back from Harrison in the "Clash for Cash" and Josh Cartwright and Josh Osby each have two Top 5 finishes in the Clash and sit in third and fourth, respectively. Cartwright gets hometown advantage this weekend, too.

Round 4 marks the second stop in Tennessee and is held again at the Agricenter International. Check out the animated track map:

The AX Tour takes a three-week break before resuming January 3, 2015 (same day as Supercross Round 1) with four straight races and possibly six if race officials get approval for a Macon, GA date on January 31, 2015. The series concludes on Feb. 7, 2015 in Tunica, MS.

The Clash for Cash event brings the Top 10 riders from the AX Pro and AX Lites races to compete head-to-head in a 20-lap main event. Riders earn points in each class as well as the Clash for Cash, which offers the highest payout of all the races. The new AX Tour season is capitalizing on last year's record breaking turn-out as more than 30 riders entered for both the AX Pro and AX Pro Lites classes. Additionally, more than $175,000 in cash and contingencies is up for grabs this year.

Doors to Round 4 open at 6 p.m. and gates drop at 7 p.m. Buy advance tickets or at the box office, 7777 Walnut Grove Road in Memphis, TN.
