MotoAmerica KTM RC390 Cup
The MotoAmerica KTM RC Cup debuts at Road America in Elkhart Lake, Wis., May 29-31. The class was designed with budget in mind; KTM will sell you a 2015 RC 390 Cup race bike for $9,999. Rules state competitors must endorse an AMA Superstock Limited license, and be born between 1993 and 2001.
MotoAmerica’s spec class for riders aged 14-22 – the KMT RC 390 Cup – begins at Road America on May 30. The series will feature 24 riders from 14 states, Mexico and Canada. Some known last names will vie for points in the KTM RC390 Cup, including Ezra Beaubier – the brother of Cameron – and Ashton Yates, the son of nine-time AMA Superbike race winner Aaron Yates.
Based on the street-going KTM RC 390, the Cup race bike offers upgraded fully adjustable WP suspension, an Akrapović muffler, a KTM PowerParts 320mm front rotor, racing brake pads, stainless-steel braided brake lines, adjustable hand levers, racing footpegs (with optional “upside-down” shift pattern), racing bodywork (with larger windscreen), racing chain and sprockets, removed ABS, and a lower fairing that doubles as a oil catch.
Buying a street legal RC 390 ($5499) and adding these pieces would cost $3500 more than the RC 390 Cup Race Bike.
The 43mm inverted WP forks are adjustable for compression and rebound damping, as well as spring preload. In the back, the WP shock has spring preload adjustments, shock length, rebound damping and high- and low-speed compression damping adjustments.
The high-revving 373cc liquid-cooled DOHC single is stock, though it uses an Akrapović muffler. An RC Cup spec intake restriction plate is mandatory, and included.
By removing the ABS, the RC390 shed 2.6 pounds. Other weight savings arrive from the racing bodywork and final drive components. The wheels and frame on the race bike are the same as on the standard KTM RC 390.
In addition to cash payouts for win, the series winner will be taken to Silverstone Circuit in England to compete in Round 11 of the 2015 British Superbike KTM RC Cup Series. Included are travel and hotel expenses, as well as a fully prepared KTM RC 390 Cup Series Bike and KTM trackside support.
“We are super pumped to have the KTM RC Cup in our series,” says Wayne Rainey, three-time 500cc World Champion and MotoAmerica President. “We think it’s a great opportunity for both young and new racers who want to be a part of the National Championship. If something like this was around when I was starting road racing, it would have been something I would have pushed really hard to be a part of. We expect to be finding some new talent from this, and that’s what the MotoAmerica series needs.”
