He first started racing in 1996 at the age of 15 in the Italian 125 Sport class, winning the title two years later before moving up to 125GP in the Italian and European championships. In 2001 he moved to 250GP but his season wasn’t a successful and he was forced to take a one-year break from racing in 2002.
2003 saw him racing for Rox Ducati in the FIM Superstock 1000 Cup. He lost out on the title by three points. In 2004 he moved to the Supersport World Championship riding for Ducati Breil finishing the season in 5th place.
In 2005 Lanzi joined the Caracchi Ducati team in the Superbike World Championship. He had a poor start of the season and injury kept him out of two rounds. A series of 8 successive top ten finishes earned him a promotion at the EuroSpeedway Lausitz round where he raced for the Xerox sponsored Ducati factory team in place of the injured Régis Laconi. He took pole position for the races. In race one he overshot the first corner and had to go down an escape road, seeing him cut several corners. He rejoined third, but had missed enough of the track to earn a ride-through penalty, dropping him down the field, although he fought back to 8th. However, in race 2 he took the win ahead of Chris Vermeulen and Noriyuki Haga. He got his 2nd superbike win at Magny-Cours race 2 later that year.
His 2005 performance was enough to earn him a place on the factory team for 2006. However, whilst team-mate Troy Bayliss dominated the season, Lanzi did not win any races. He finished the season 8th overall. He remained in the team for 2007, but he was once again overshadowed by his team mate and he was often behind Ruben Xaus who was riding a 2006-spec Ducati.
He was dropped by the factory Xerox Ducati team for 2008 but continues to ride a Ducati, for Team RG. He took victory in Valencia race 1 - he overtook Troy Bayliss for third on the final lap, just before Max Neukirchner and Carlos Checa collided while battling for the lead. However, this was his only top-5 finish of the season, and he came 14th overall.
