[7] In early 2016, Walker announced he would no longer participate in superbikes, instead switching to the British Sidecar Championship, initially with a two-year contract.

He predicted that "For me it's going to be the toughest year ever",[citation needed] which proved accurate, as the factory Shell-sponsored Honda was hard to ride and forced Walker to override, resulting in many huge crashes.

[13][14] Walker initially struggled on the Rizla Suzuki in the British Superbike championship, occasionally outpaced by rookie team-mate Cal Crutchlow.

The team insisted it wasn't, and at Oulton Park he took third in race one, in tricky conditions which saw many top riders (such as Jonathan Rea, Gregorio Lavilla and Tom Sykes) crash out.

He was not retained for 2008, but raced in the Supersport World Championship for the very first time in and 2008, for the GIL Kawasaki team alongside teammate Katsuaki Fujiwara.

It looked like he would not be racing in 2010, but he arranged a deal with on a privately run Suzuki tuned by former BSB rider Ray Stringer just a week before the opening round.

[20] After 2 races Walker was offered a ride in the MSS Kawasaki team when Simon Andrews was injured in a crash while guesting in World Superbikes.

According to an article by Oli Rushby on Motorcycle News.com, Chris Walker sustained injuries during the "eight round of the 2017 MCE British Superbike Championship at Cadwell Park after a nasty crash in Friday’s Sidecar session.

"[25] Rushby went on to report that "[t]he multiple BSB runner-up crashed his Kawasaki-powered Santander Salt outfit at Mansfield and was taken to hospital with suspected back injuries", before being "confirmed he sustained a break to his T4 vertebrae... as well as a broken nose."

Walker is planning on participating in the Hyundai Construction British Sidecar Championship with TAG Racing[26] with the support of team-mate Tom Christie.
