Likely to be marked as the start of significant chapter in MotoGP history, the claiming rule teams (CRTs) were out in Jerez the past three days testing their MotoGP machinery, which is comprised of production-motorcycle motors with custom-built chassis. While not the first time we’ve seen a CRT bike on the track, the outing was the first time that  a”top-tier” rider was on-board the new racing format motorcycles, as Colin Edwards lead the charge with his BMW/Suter machine with NGM Forward Racing.

Many in the MotoGP paddock have been waiting to cast their verdict on the CRT endeavor, withholding their judgments until a top GP rider took to the helm of a CRT machine and properly put the bike through its paces. With tests earlier in the year showing Mika Kallio on-board the BMW/Suter to be over six seconds off the pace of the 800cc-era machines, the CRT future of MotoGP looked to be in jeopardy. Those lap times improved over the year to be “only” four seconds off that 1,000-era bike pace, showing improvement, yet a gap  to the front-runners.

Now with Edwards finally swinging a leg over the BMW S1000RR-powered Suter prototype, surely more comparisons between the factory prototypes and CRT offerings are to ensue. Posting a best lap time of 1’40.188 at the Spanish GP earlier this year, Edwards was roughly 2.5 seconds off his own pace, finishing the three-day test with a best lap to f 1’42.6. That news seems discouraging on its face, though it should be noted that the team dropped 1.3 seconds between Wednesday and Thursday’s tests.

Edwards also rated the bike at about 65% of its potential, while the Texan’s own fitness was questionable, as Edwards was till recovering from the injuries he sustained at the Malaysian GP. WIth all those caveat, does this week’s test equate to excuses for a lackluster performance, or justify that more leaps and gains will be made before the start of the 2012 MotoGP Championship?
