The Kiefer Racing Moto2 team’s 2018 season looks in doubt after a deal to run KTM chassis fell through after a key investor backed out.

The team was struck by tragedy in 2017 when team owner Stefan Kiefer passed away during the Malaysian Grand Prix weekend.

The future of the team looked secure for next season when it was sold to David Pickworth, with the German squad set to field Dominique Aegerter and 2012 Moto3 world champion Sandro Cortese on KTM frames.

However, with contracts set to be finalised this week, a key investor has pulled out, with Aegerter admitting he will be forgoing his salary in a bid to keep the team on the grid next year.

“The investor, who was supposed to give Pickworth the money, has left and as a result the KTM deal was annulled,” the Swiss rider told news outlet Motorsport.com.

“We though everything was alright two weeks ago, and today and tomorrow it was planned to sign the deal between team and rider and investor.

“But it fell through.

“We now need to have a look how to proceed. For us this is also a complete new situation, but we’ve made a plan B two, three weeks ago already.

“We’ll now see that everything gets together and that we can work with Kiefer and, of course, KTM.

“We need to find money. I’ll be investing myself and relinquishing my salary too.

“It is a shit time, it is three days before Christmas and it is additional stress when everyone is stressed anyway already.

“But I won’t give up and my clear target is to race Moto2 on a KTM chassis and for Kiefer Racing.”

Aegerter finished 2017 12th in the standings on 88 points after his Misano win was stripped due to a technical infringement, while teammate Tarran Mackenzie – who replaced Danny Kent – was 37th with a solitary point after a difficult transition from British Supersport to Moto2.
