Motorizer (2008–2009)

From March through to June 2008, the band convened in Los Angeles with producer Cameron Webb to begin work on their 19th album Motörizer. Mikkey Dee's drum tracks were recorded at Dave Grohl's studio. Motörizer was released on 26 August. It does not feature artwork from Joe Petagno, the artist who designed many of their classic album covers.

In June 2008 the band performed at the main stage of the Download festival Between August 6 and August 31, Motörhead joined with Judas Priest, Heaven and Hell and Testament on the Metal Masters Tour. On August 20 the band played one date at the Roseland Ballroom, New York, as part of 'The Volcom Tour 2008' which continued with bands The Misfits, Airbourne, Valient Thorr and Year Long Disaster at House of Blues, Anaheim, California on September 2, playing a further thirteen dates. The band concluded the tour without the supporting bands, playing one more show at the Roseland Ballroom on September 20, and the final gig, at the The Stone Pony, Asbury Park, New Jersey on September 21.

On 30 September, Reuters reported that Neverdie Studios had signed a deal with Lemmy and Motörhead to develop and market Lemmy's Castle and Motorhead Stadium inside the virtual world of Entropia Universe, an online virtual universe. The year's touring ended with a 34-date tour of Europe with a variety of support bands including Danko Jones, Saxon, Witchcraft, and Airbourne. On 6 March 2009, the band played in the Middle East for the first time, at the annual Dubai Desert Rock Festival in Dubai. On April 1 Motörhead are reported to have entered into a two year sponsorship deal with UK Roller Derby team the Lincolnshire Bombers Roller Girls.

In November 2009, the band are being supported by NWOBHM veterans Sweet Savage on the Irish leg of the tour (30 years after first sharing the stage together) and punk and goth rock legends The Damned on the UK leg of their world tour. On The Damned's official website, Captain Sensible is quoted as saying: "Ha ha..... we're working with Lemmy again are we? Excellent! He's the real deal, the absolute antithesis to all that the likes of Simon Cowell stand for. And for that we should all be grateful. This tour will be a celebration of all things rock 'n' roll..... pity the poor roadies is all I can say!"
