Between March 23 and August 17, 11 rounds of the 2014 MotoGP season had been played out. Marc Marquez had won 10 of those. Repsol Honda had won all.Such was the dominance of the Men in Orange last year, that the season was all but wrapped up by the halfway stage. Yamaha ran into all sorts of problems - Jorge Lorenzo, in particular - as it had to wait 13 races for its first victory, which came in Misano thanks to a man named Valentino Rossi.But, things will probably be a little bit different this year. That's not what we think, but what the top guns at both teams think. Team principals Lin Jarvis (Yamaha) and Livio Suppo (Honda) have both made statements that can be summed up as 'Marc Marquez isn't going to win everything this year'. The pre-season tests told us why.You see, during the long winter break, both teams have been hard at work on their machines. Honda's looking to make that RC213V quicker still, and Yamaha's been ironing out the chinks in the M1's armour. The blue bunch ended the last season on a bit of a high, as the M1 finally managed to give the RC a really hard time, and they're quite keen on carrying that momentum into 2015.The two pre-season tests held at Sepang were just that - tests. But, they are a fair indicator of what's to come. Marquez looked as good as ever, smashing the lap record in the first test, and consistently logging lap times in the low two minutes. The brakes seemed to be a bit of an issue in the first half of Test 2, but the team was only experimenting with different chassis setups and the like. In his race simulation, Marquez notched up the quickest laps. Just when you thought Yamaha had almost drawn level, Suppo and his men seem to have dropped a gear and taken off once again.Dani Pedrosa is... well, there, but not quite. He's fast, yes, but will he be able to keep up with his team-mate on race days? He looks fairly content with where he is at the moment\: on his RC213V, a little behind Marquez's.One man who seems to be hell-bent on stopping the Marquez juggernaut is Yamaha's Jorge Lorenzo. He has toiled right through the winter break, and is looking fitter. In Sepang, he was the only rider who seemed capable of getting close to MM93's lap times consistently.Valentino Rossi still hasn't given up on his dream of making it a nice round 10 world titles. And, why should he? For the better part of 2014, he was the stronger rider in the blue corner of the ring, and he's shown in both the pre-season tests that given the right equipment, he has the pace to bother the Hondas, and, of course, his Spanish team-mate.Talking of equipment, Yamaha has finally fitted the M1 with a fully seamless-shift gearbox (SSG, allows smooth, clutch-less upshifts and downshifts and cuts down on shift times), much like the one found on the big H. It may still be some way away from the Honda's unit in terms of precision and refinement, but it's definitely going to help the Yamaha men get dangerously close to the Hondas.Losail, which hosts the first race of the 2015 season, is a dusty track that's better suited to Yamaha. But, that's just the first of 18 rounds this year. It'd take a brave man to bet against Marc Marquez making it three MotoGP titles in as many seasons.The outsidersDucati's MotoGP machine isn't meant for everyone. Since Casey Stoner left the team, no rider has been able to crack the code on the Big Red. Andrea Dovizioso has done well, but in patches. But now, with the kind of we'll-fix-everything attitude that team boss Luigi (also Gigi) Dall'Igna has brought to the table, things are looking up.Quickly realising the fact that it was the bike that needed to be changed, Gigi has commandeered an all-new, shapelier, more compact bike, the GP15, which, as seen during the Sepang tests, suffers from none of the massive understeer and mid-corner stability issues that plagued the GP14. This, too, gets a SSG, and since Ducati is a manufacturer that enjoys the Open class benefits, the GP15 can also carry upto 24 litres of fuel in a race, and choose to have an extra soft rear tyre. The Duc was sufficiently swift in the tests, prompting Vale Rossi to label the concessions the Italian team enjoys as unfair. Andrea Dovizioso is around, and has another Andrea (Iannone, who graduated from the satellite Pramac Ducati team) for a team-mate this year.If Ducati registers a single win, two second places or three third places in dry conditions, its fuel allocation will be reduced to 22 litres. That won't make any difference to the Bolognese brigade, because, as it stands, its bikes only need 21-22 litres in a race. If the Andreas manage to put together three dry race wins, that'll reduce their fuel allowance to 20 litres, and see the extra soft rear tyre option being taken away from them entirely. That will hurt a bit, but three race wins will hurt Honda and Yamaha even more. And, the way the bikes are shaping up, the one dry victory that'll deprive Ducati of those two litres of fuel in 2015 may not be too far off.Trying elsewhereFor the third time in as many seasons, Cal Crutchlow is starting afresh with a new team. He was a Tech 3 man in 2013, who couldn't resist the allure of a factory ride, choosing to switch to Ducati for 2014. Many thought it to be a disastrous move, and it was exactly that. He had no results in nine races - that's half the season, mind you - with just one third place finish. The Briton lost faith in the Italians, and, when the opportunity presented, moved to the bike he thinks can win him races\: a Honda.He's now one half of the renamed CWM LCR outfit, Honda's satellite team. LCR's also given him a factory-spec RC213V to ride, which is quite similar to what Marc Marquez is on, but of course, it runs a different electronics package, which makes a big difference. Still, that Honda is plenty quick, and astride it, Cal's at least got a realistic chance of staying in the top five throughout this season.Open one last time2015 is the second and last year for the 'Open' class in MotoGP. Ducati located a loophole in the MotoGP rulebook, and used the extra concessions it to its advantage, much to the displeasure of the other two manufacturers. All manufacturers would eventually jump into the 'Open' class to gain those extra benefits, and to prevent that from happening, MotoGP will have no such divisions from 2016 onwards. It'll just be one big class, with everyone sharing the same control 'spec ECU' hardware and software.ReturneesMotoGP is a richer place with the return of two big names\: Suzuki, and Aprilia. Suzuki had pulled out at the end of 2011 citing financial troubles, but it is back now, and, with two talented riders, Aleix Espargaro and Maverick Vinales, riding bikes that are getting faster with every passing session, looks set to put in a strong performance this year. Aprilia, on the other hand, quit the scene in 2004, but has been around since 2012, supplying bikes to the Aspar Open team. It has taken the same prototype, and modified it a little for its factory return. Both teams will enjoy the same advantages as Ducati\: extra fuel, softer rear tyre option, and freedom to develop their engines and software right through to the end of the year.There's another party making a return, but it's not a team, it's ex-MotoGP rider Marco Melandri. The Italian was quite a solid performer back in the day, but he left GP racing for the World Superbike c'ship, and only returned to MotoGP because he had no other choice. It has shown in the pre-season tests, as Melandri has consistently managed to stay at the back of the pack. An all-new bike is due next year, but until then, it doesn't look like Aprilia (and Melandri, in particular) will be having too much fun.The greenhornsOne of them is in MotoGP through natural progression. One of them has shot right to the top in highly unusual fashion.Maverick Vinales won the Moto3 class. He also won several Moto2 races. Clearly, stepping up was the next step for him, and so, he's now at Suzuki. Just how it is supposed to be done.Don't tell Jack Miller how it's done. He won't care. The Australian ended second only to Alex Marquez in the Moto3 category last year, and, instead of making the gradual, expected switch to Moto2, he's come barrelling into the top tier, forming the second half of the CWM LCR Honda team.To pit the two rookies against each other wouldn't be right\: Vinales is on a Factory ride, and is most likely to be vying for a top-10 spot all through the season. Miller, on the other hand, is on the inferior RC213V-RS, and will likely end up sparring with other Open class bikes for lower point-winning positions.
