Mugen bright sparks make major changes
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.”
