Mu­gen bright sparks make ma­jor changes

Motorcycle News (UK) - - This Week -

The main changes from Bruce An­stey’s 2016 Zero Tt-win­ning Shin­den 5 to the sixth in­car­na­tion of the Mu­gen electric bike in­volve the mo­tor and the bat­tery in­ver­tor.

“The bat­tery cool­ing sys­tem is a new de­sign,” Ku­nio Yoshimi, the Shin­den’s chief de­signer, ex­plained.

“Bat­tery tem­per­a­ture has been a prob­lem and the new sys­tem weighs less. The mo­tor is also new, made in-house by Mu­gen.”

Over­all these changes shave 5kg off the new bike. The team were also test­ing a new shock and link­age which will make the rear sus­pen­sion more ad­justable.

Im­proved aero­dy­nam­ics and new soft­ware to con­trol bat­tery out­put, com­pletes the tweaks for 2017.

Mu­gen run a sim­u­la­tion for the bike over the TT course each year and the pro­jected tar­get for Shin­den 6 in 2017 is a 122mph lap, 2mph two faster than Mcguin­ness’s cur­rent record set in 2015.

“If we can achieve the tar­get we can win,” Yoshimi smiled, then added: “We feel that some day it may be pos­si­ble for an electric ma­chine to match the speed of a con­ven­tional bike on the TT course.”

More a work of art than a bike
