‘It’s also pos­si­ble KTM have fit­ted a sec­ondary bal­ance shaft’

Motorcycle News (UK) - - This Week -

en­gine man­age­ment sys­tems not only give more power but also in­crease fuel econ­omy. There is also the pos­si­bil­ity that KTM will have fit­ted a se­cond bal­ancer shaft in the cylin­der head, as first seen on the firm’s 690 Duke launched at the end of 2015. This ex­tra bal­ancer shaft works to smooth out the low rpm en­gine re­sponse, giv­ing near twin-like smooth­ness from a sin­gle cylin­der.

The 390 Duke has been a stun­ning suc­cess for KTM around the world, and – in ad­di­tion to the smaller ca­pac­ity 125 and 200 Duke mod­els – has helped the Aus­trian com­pany be­come Europe’s big­gest man­u­fac­turer by vol­ume. The new Duke is also ex­pected to gain a mid-ca­pac­ity sta­ble­mate in 2017/8 in the form of a new 800cc par­al­lel twin, as re­vealed in MCN last week.
