Richardson averaged 9.13 in the Elite League last season
Lakeside Hammers have revealed their 2011 line up, with a familiar top four of Lee Richardson, Peter Ljung, Adam Shields and Piotr Swiderski.
Kauko Nieminen and Robert Mear will ride at five and seven respectively.
Stuart Robson and Kyle Legault double-up at number six, meaning every rider has Hammers experience.
"We're fortunate that we've been able to put a team in place that we believe is stronger than last year's line up," co-promoter Jon Cook told BBC Essex.
"It's always been very important that the guys want to ride for Lakeside and they're not just hoping to get a ride in England and it happens to be at Lakeside."
At the end of the season we were talking to him about the option of putting him out on loan somewhere

Richardson, 31, became a permanent fixture at the Essex Raceway last season, after joining from Elite League rivals Swindon, and this year's team was always going to be built around his 8.45 green sheet average.
Swede Ljung, 28, made a late switch from the Robins in 2010 on loan before becoming a Hammers asset, and helped turn his new side's fortunes around.
And while 33-year-old Australian Shields failed to hit his usual heights, the result has been a slightly lower average and Cook has taken advantage.
"He had a host of setbacks away from speedway which you sometimes take into your racing," he said.
"At the end of the season we were talking to him about the option of putting him out on loan somewhere.
"But when you get to the winter and you look at the riders available and their averages, you realise you don't want other teams to have the benefit of his low average."
Nieminen will be looking to build on his Hammers reputation in his third year at the club, after picking up an average of 6.03 points across 33 meetings last year.
Swiderski joins on loan from local rivals Peterborough while former Ryehouse Rocket Mear, who rode for Lakeside two seasons ago, returns from a venture into grass track racing.
And Robson, who suffered numerous technical issues in 2010, is joined by Canadian Legault, who guest rode for the Hammers once last season.
