Haslam tests new en­gine spec

Motorcycle News (UK) - - Sport -

He might have stormed to a dom­i­nant dou­ble in the open­ing round at Don­ing­ton Park, but there’s been no rest for se­ries leader Leon Haslam, who was back out on track at the Le­ices­ter­shire cir­cuit on Thurs­day.

Hav­ing started the sea­son with 2016 ZX-10R mo­tors, the team have been work­ing be­hind the scenes on the ’17 spec ZX-10RR en­gine and Haslam took a quick run out at lunchtime on Thurs­day to see whether the im­prove­ments seen on the dyno trans­fer to the track.

“We spent all win­ter work­ing on the 2016 mo­tor but the 2017 ZX10RRS didn’t ar­rive un­til a lit­tle while be­fore the sea­son so we de­cided to use what we knew for Brands,” he ex­plained.

“Not want­ing to mess about with en­gines in a race week­end, we booked a lunch ses­sion at Don­ing­ton Park and all went well. It’s re­ally pos­i­tive on the ac­cel­er­a­tion side of things but there’s a bit of work to do on de­cel­er­a­tion, es­pe­cially with en­gine brak­ing but we knew that as it took us all win­ter to get that right on the older spec mo­tor.”
