JEFFERSON, TX, APR. 8-10, 2016

Diamond Don and AHRMA teamed up again to present the biggest and most fun Vintage Off-Road motorcycle race in America! Unlike last year’s rain and mud, this year the weather was solid – partly cloudy and a light breeze, which made for a fast track. AHRMA set an all-time record for post-entries at 360 for the weekend. Allowing racers to register for Saturday and Sunday at the same time improved the process. More than 900 patrons came through the gate; that’s up from 700 last year. Trials also broke a record, with 27 this year.

Trey Jorski was a Kawasaki jockey on Saturday at Diamond Don’s 14th annual Riverport National.

Country-music star Lyle Lovett came out last year as a spectator, and he must have caught the MX virus: This year, he raced a 125cc Husky and scored a trophy.

Arlo Englund and his wife and sister were honored as the Legend of the Weekend. Arlo enjoyed riding the Scott Sears custom-built 1981 YZ465 and was flying around the track… until he ran out of gas.

More than $3,300 was raised for the Wetlands Foundation by the bike raffle. Bruce MacFarlane of Rapid Skunk Racing in Shreveport, Louisiana, won the bike.

Brad Lackey brought his T-shirt exhibit and signed shirts. He even had some Preston Petty shirts to help defray costs for Preston himself.

Guy Cooper and Trey Jorski were the two big names racing on this weekend. Cooper won his motos on Saturday but had to leave for a Sunday appointment. Last year’s legend, Trey Jorski, not only displayed his speed but won the golf challenge with his teammate, 100cc ace Tim Borgfield. Steve Wise brought the spirited (no pun intended) Sunday morning worship service and hung out to play for two days.

Guy Cooper (14) was top dog on the first day of the event.

Saturday’s Preston Petty Vintage race started off with a bang, as the older experts raced – the Premier 500, Over 60 and Over 70 riders. Peter Lawson took his Triumph to a double-moto victory, over Beno Rodi’s Indian.

Wes Willis got excited in the second moto and rode his Husky to victory, over CZ-mounted Mark Moore and Skip Kennedy.

Wes Willis (28Y) won Saturday’s Over 60 Expert contest.

In the Over 70 class, it was Californian Ray Atkinson taking his BSA to a double-moto win, over Diamond Don and Zahn Lewis.

Floridian Mike Brown won both motos, ahead of 14 other riders, in the Over 60 Intermediate class. A couple of Texans on Hondas finished behind him – Mark Kowalczyk and Kevin Brown.

Another 14-rider gate was the one for the Over 50 Experts, which, not surprisingly, was won by Guy Cooper. However, a game Trey Jorski made him earn it. Jorski was leading coming out of the woods, but he got too deep into the sandy turn and missed a gear, and then another coming over the levee jump, which allowed Cooper to take over for good. Phil Reed put in a good, strong ride to finish third. Two of the suspension tuners (of the three who were in the pits) had their own race; Clark Jones bested Rhett Smith for the fourth position.

Trey Jorski (49), Guy Cooper (14) and Phil Reed (17R) lead the pack off the start of Saturday’s Over 50 Expert contest.

Maico-mounted Tim Clendenin made North Carolina proud by winning the always large Over 50 Intermediate class. Although Mark Hosbach won the first moto, he tallied a DNF in the second stanza, which opened the door for Gary Davis’s Maico, Bill Walker’s Bultaco and William Denner’s Husky.

One of the stories of the weekend was about the Thomas brothers, as Cody “the Youngster” and Chad “the Youngest” were riding their Orazio Hondas like they had stolen them. At one point, they had Bultaco star Mark Stalhman in a sandwich.

“Yeah, it was me and Cody and Chad on the little 125s, screaming down the back straightaway, whiskey-throttling wide open over the bumps,” Stalhman reported. “The spectators were jumping up and down, going crazy! We came over the ‘Big Air’ jump side by side; no one wanted to let off. Then my bike blew up!”

Chad Thomas (333) was a busy man all weekend in Jefferson, Texas.

Older brother Cody went on to take the double-moto victory when Chad had bike troubles that sent him back to fifth. Travis Shackelford took second in the first moto, but Chad came back to take second, behind his brother, in the second moto. Ohio rider Jeffrey Clark took second overall with his 3-3 tally, Shackelford was third with his 2-4 score, and Thomas was fourth with his 5-2 results for Louisiana.

CZ-mounted Clark Jones won the double-moto victory in the Sportsman 250cc Expert class, over Texans Matthew Mosely and Travis Shackelford. Trevor Tollett was fourth.

Not to be outdone, the other suspension guru, Rhett Smith, took his CZ to a double-moto victory in the Sportsman 500vv Expert class for South Carolina. He beat Bart Watts, Jeff Acklen and Dale Burroughs.

Guy Cooper brought his Oklahoma Suzuki to victory in the Open Age Expert class, over Texans Bubba Dennis and Matthew Mosely.

The weather was great on Sunday, too, with a few clouds and a gentle breeze to keep the heat down.

While Guy Cooper won the DD 100 Challenge Expert class on Saturday, it was Cody Thomas who won on Sunday. He had actually stayed right on Cooper’s rear fender for a couple of laps on Saturday before they got tangled up with a lapper and Thomas had to retire with a handlebar through his goggles and a shifter wrapped around the peg. On this day, Thomas had the track to himself. Michael Keating stayed in second, and there was a hot battle between Louisianans Bryce Landry and Stuart McAvoy; they swapped third and fourth behind the leaders for their finishes.

Cody Thomas (668) rode his Yamaha to the win in the DD 100 Challenge Expert contest on Sunday.

Tommy Cannon rolled to victories on his Husky in the Historic 500cc Expert class, in front of Alan Drane and Peter Lawson.

In GP 125ccc Expert action, Murray Kaiman took his Suzuki to the overall win, over Doc Tollet’s Honda and the off-road director, Fred Guidi.

Cannon got a new Maico recently, and he rode it to victory in the GP 500cc Expert class.

Louisiana speedster Joel White won the first moto of the Ultima 500cc Expert class, but he had to settle for fourth in the second moto when he ran out of gas. Texan Gary Emerson took the overall with his 2-1 tally, over Colorado’s Scott Sears (3-2).

White went on to win the Ultima 250cc Expert class as well.

Gary Emerson (9R) went 2-1 for the overall Ultima 500cc Expert victory. Joel White (742) took third overall in that class with a 1-4 score. Tommy Cannon (718) blasted to the Historic 500cc Expert and GP 500cc Expert wins.

I can’t speak for my announcing partner J.P. Parsons, but the most exciting moment of the day for me came in the Over 50 Expert class. Hoot Parker and Trey Jorski were battling so hard and close that you could have thrown a blanket over them. Parker made the most beautiful two-turn pass to take the lead for good, right in front of the announcing stand!

“I noticed he [Jorski] was drifting outside as I followed for a couple laps,” Hoot said. “At the flag turn, I ducked inside and decided to keep the inside through the mud in the left-hand sweeper, gambling that my bike would hold. It did. Then I cut back behind him to the next right-hander to take the inside line.”

As this reporter was watching all this unfold, I held my breath when he went through the mudhole, as hardly anyone else was doing it. Jorski managed to stay ahead of him, but without letting off, Parker brushed his rear fender to cross into the inside. I told Hoot at the trophy presentation that he now had a target on his back for next year. Gary Emerson and Stuart McAvoy finished behind them.

Trey Jorski (49) was Honda-mounted on Sunday, taking runner-up in the Over 50 Expert contest.

Room does not allow for all the racers and their individual stories, but many thanks to them for putting their money, bikes, health and skill on the line for the show!

Diamond Don would like to thank all the sponsors, racers, employees, volunteers and AHRMA. Without their support, he couldn’t have pulled off this race. A special thank-you goes out to Willie Turlington for working around the race course and Melissa Moit for working long hours to answer questions and organize race details and events. A big thanks also goes out to Mike Haynes and Chicago Jerry for all their prep work on the CC course, and the Jay Huffman trials crew.
