New Husky su­per­moto adds light­ness to grunt

The Witness - Wheels - - BIK­ING - SPIROS TSAN­TI­LAS — Giz­mag.

HUSQ­VARNA has un­veiled the new FS 450 su­per­moto.

The new Husky fea­tures a new frame, en­gine and gear­box, prac­ti­cally mak­ing for a new mo­tor­cy­cle. The driv­e­train is based on the mo­tocross KTM 450 SX- F that’s un­der­gone a stren­u­ous re­design re­sult­ing in a 1,8 kg lighter and more com­pact en­gine unit.

It is mated to brand- new fivespeed gear­box, smaller and lighter than its pre­de­ces­sor, which is equipped with the APC ( Adler Power Torque Clutch) slip­per clutch to elim­i­nate rear end hop­ping when brak­ing and down­shift­ing into a cor­ner en­trance.

The sin­gle- cylin­der en­gine is con­trolled by the lat­est evo­lu­tion of Kei­hin’s En­gine Man­age­ment Sys­tem — the same elec­tronic unit used by KTM.

In the case of the 2016 FS 450, a new launch con­trol func­tion reg­u­lates torque out­put dur­ing the first two sec­onds af­ter a stand­ing start, help­ing to max­imise trac­tion.

The mo­tor­cy­cle is built around a new chromium molyb­de­num

. tubu­lar steel frame with a new alu­minum swing- arm.

The plas­tic sub­frame in­tro­duced in the 2014 FS 450 has now been re­placed by a smaller and lighter car­bon- com­pos­ite part.

The 2016 FS 450 is en­dowed with the typ­i­cal gear that KTM uses, such as the fully ad­justable WP sus­pen­sion and Brembo brakes, plus a light­weight pair of black Alpina spoke wheels to com­plete the pack­age.

Af­ter all the weight- sav­ing and power- en­hanc­ing de­vel­op­ment work that went into the new FS 450, the out­put of 47 kW marks the most pow­er­ful en­gine ever used in a 450 cc Husq­varna su­per­moto. This much grunt in a mo­tor­cy­cle that weighs in at just 105 kg sounds like an ex­plo­sive com­bi­na­tion — ex­actly what it takes to com­pete in the S1 World Su­per­moto Cham­pi­onship.

For ref­er­ence, the 2014 FS 450 pro­duced 44,7 kW for a mass of 110 kg.

The 2016 FS 450 is ex­pected to hit Husq­varna’s deal­ers by the end of Septem­ber at an as yet undis­closed price.
