The claiming rule team (CRT) bikes are both figuratively and literally under the spotlight at Qatar this race weekend, with their production-based motors and prototype frames shaking up the norm of pure prototype racing. Both an effort to take power away from MotoGP’s MSMA, which is comprised of Ducati, Honda, & Yamaha, and as an effort to lower the cost of racing in MotoGP for its participating teams, the CRT experiment is getting its first real test this weekend.

Swelling MotoGP’s grid with an additional nine-racer entries, the CRTs have certainly helped fill MotoGP’s ranks, though mostly with riders we are not familiar with. Leading the CRT charge is American Colin Edwards, and he is joined by Randy de Puniet, who didn’t wish to be on a CRT for the 2012, but has still found himself at the top of the heap. These two veteran MotoGP riders have been accompanied by seven riders that hail from a range of world and national championships that span everything from Spanish Superbike (CEV) to British Superbike to the Moto2 Championship.

Since on Sunday morning, MotoGP fans are going to have learn the names of these new riders and the bikes they ride, we have put together a primer on the CRT entries for the 2012 MotoGP Championship. Bios, specs, and notes on all nine MotoGP CRT entries are after the jump.

The Aprilia ART, as it has become known in the GP paddock, is so far the most competent claiming rule team package (CRT) on the MotoGP grid. Powered by an Aprilia RSV4 Factory motor that is World Superbike spec and beyond, the Aprilia ART also features a chassis that has been developed by the very same Italian company. A turn-key CRT package offered by Aprilia, if you believe the rumors circulating in MotoGP, the Noale-based company’s involvement with the ART doesn’t stop at delivery.

Rumored to be the byproduct of Aprilia’s aborted MotoGP campaign, in the World Superbike paddock the RSV4 is described as a MotoGP bike that was sold to consumers with WSBK domination in mind. Taking the World Superbike Championship in only the team’s second year in the series, Max Biaggi and Aprilia have helped perpetuate that rumor further, and currently lead the 2012 Championship as it races into Imola this weekend.

If a few years ago all the paddock gossip was about how Aprilia managed to campaign a thinly veiled MotoGP bike in WSBK, then this year the talk will surely be how the Italian factory snuck its superbike onto the MotoGP grid. Despite the irony in that statement, it takes only a casual glance at the Aprilia ART and Aprilia RSV4 Factory WSBK to see the immediate similarities between the two machines.

One of the biggest compliments ever made regarding the Aprilia RSV4 was actual meant to be a criticism, as when it came time to homologate the RSV4 for World Superbike racing, the competition cried afoul — saying the RSV4 Factory was really a MotoGP bike in a production bike’s clothing. Said to be the leftovers from Aprilia’s aborted MotoGP effort, the Aprilia RSV4 had a meteoric rise in WSBK, and won the Championship after only the company’s second season back in the series.

It should come then with little surprise that the Aprilia and its V4 motor has been the popular choice for teams in the MotoGP Championship looking for a claiming-rule team (CRT) solution. Dubbed the ART, the Aprilia-powered CRT bike also features an aluminum chassis that is designed by the Italian company. Thus with Aprilia offering essentially a turn-key GP solution for teams like Aspar Racing, it probably shouldn’t shock us that the similarities between the production WSBK-spec RSV4 and prototype ART being almost too close to distinguish between the two, even down to the bodywork.

Given the fact that Dorna desperately needs an alternative to prototype racing machines built by Ducati, Honda, and Yamaha for its CRT gamble to work — not to mention the need for CRT bikes and teams that are competitive on the track with the bikes from the OEMs — one can only imagine that Dorna is turning a blind eye to obvious “bending of the rules” that is occurring with the ART project. If the ends justify the means, then surely none of this matters to Ezpeleta et al, and right now Randy de Puniet and the Aspar Racing team’s CRT effort are the MotoGP rights holder’s best bet at recapturing control of MotoGP racing.

That all being said, the Power Electronics Aspar team debuted its ART race bike, and as is the custom, disclosed only some of the most basic technical specifications about the machine. At the helm of Aspar’s ARTs will be Randy de Puniet and Aleix Espargaro, and while the CRTs as a whole have been off the pace of the prototype bikes, RdP’s pace on the Aprilia has been noticeably quicker, and could give some of the slower satellite riders a run for their money.
