Reduced to the max! The new KTM 390 Duke has everything thathas always made great bikes great: sufficient power, ample torque, and low costsat an extremely low weight. It handles extremely well and comes into its ownwherever nimble agility is called for. In short: no other bike offers moreriding fun for your money than the 390 Duke!At a full 44 hpfrom 375 cc of displacement, it’s head and shoulders above its 200 cc sistermodel, while the chassis has of course been enhanced to cope with the extraoomph. Still, the new 390 Duke weighs in at less than 150 kilograms fullyfuelled – not only raising its dynamics above many a higher-capacity bike butalso making it a sporty alternative to pricey maxi scooters.A NEW FAMILY MEMBERThe Duke family tree struck roots already in 1994, when the first fully-fledgedKTM street bike, the original Duke, came into the world of motorcycles.
To thepresent day, the Duke has seen four evolutionary stages, reaching itspreliminary peak with the R-Version of the current 690 Duke. 2011 for the firsttime saw a smaller offspring in form of the extremely successful 125 Duke, whichpromptly went to the top of the European sales charts, selling more than 10,000units in the first year of its existence. In the spring of 2012, the 200 Dukefollowed, and now the 390 Duke closes the gap to the larger models 690 Duke and990 Super Duke R. And we can already tell you – this family is going to getstill bigger in future!ENGINE & CHASSISThanks to the typical, compact KTM design, the 390 Duke’s highly sophisticatedsingle cylinder engine weighs in at only 36 kilograms.
Two overhead camshafts,four valves, a forged piston and a Nikasil-coated cylinder ensure, among otherthings, that the 375 cc are good for 44 horsepower. The power enhancing forcefeed lubrication with crank case evacuation lowers the crank drive’s rollingresistance, contributing to the powerful torque. The ultra-light trellis frameand cast aluminium swingarm round off a compact package. Top quality suspensioncomponents by WP Suspension, disc brakes developed by Brembo and thedisengageable 9MB ABS by Bosch are standard and add even more riding dynamics,as well as safety while powering through the twisties.Review:Okay, let’s start with the most important piece ofnews about KTM’s new 390 Duke. KTM Australia have priced the machine at $6995plus on road costs. A KTM at budget prices? And it marks a shiftin focus from the Austrian brand to concentrate on bringing more bang for buckto their showrooms.The savings that have enabled KTM to enter this new low-price area of the marketcome from shifting production of the small Duke range to India via 47 per centstakeholder Bajaj Auto.
A massive powerhouse of a company that is teaching KTM athing or two about production techniques, quality control and is helping tobring KTM’s flair for design and performance to the masses. The 390 Duke will bethe first KTM model sold across their entire 76-country market.The KTM 390 Duke is a lithe machine with its bright orange laser-cut steeltrellis frame standing out from the shrouded 11-litre fuel tank, with a distinctsharp taper to nothing as the bodywork terminates at the rear. So short is thebodywork that a very lengthy rear mudguard juts out markedly backWards to tryand shroud the road spray thrown up by its 150/60 ZR 17 rear tyre. The bodyworkitself is so short that it terminates in-line with the rear axle.Like all Duke models before it, the 390 is all angles and sharp changes ofdirection, yet somehow still manages to carry it off with a great degree ofstyle. To my eye KTM do nakedbike styling better than anyone, the 990 SuperdukeR looks brilliant and the coming 1290 Superduke R promises to bring new levelsof awesome to factory built Nakedbikes.On the 390, the rims look great and the cast swingarm is super tasty incomparison to the box-section mild steel or aluminium on similar machines.

Allthe components have a look of quality about them. Perhaps the only thing thatdoesn’t look horn is the rear sprocket. KTM can, of course, sort you out with amuch tastier anodized aluminium sprocket along with all manner of other thingsvia an extensive accessories catalogue.
To really see the fine detail touches onthis machine check outour comprehensive pictorial here.The extremely naked profile and single-cylinder engine has helped keep theclaimed dry weight down to a tiny 139kg. That is more than 20kg lighter thanHonda’s CBR250R, more than 30kg lighter than Kawasaki Ninja 300, and nearly 40kglighter than Honda’s new CBR500R. This is a seriously light bike - a great assetthat makes for a very forgiving package.It also feels very small, but somehow managed to cater fairly well to riders ofall sizes on the launch. Those over the 6-foot mark felt a little locked in withtheir knees against the tank shrouds, but still comfortable enough to spend afull day in the saddle without much complaint. The tiny little shroud above thecomprehensive instrumentation seems, remarkably, to actually help a little withthe wind, although this is still a very slim nakedbike thus weather protectionis minimal.Ergonomically, I felt at home pretty much straight away and the Duke 390’s perchis not an unpleasant place to be; relatively vibration free, at least until youstart sustained cruising at speeds over 120km/h when a few niggling vibes startto appear. There is a pillion seat but I imagine taking anyone further than ashort 10km commute would involve some serious hate.The engine is a high-tech four-valve unit with DLC coated finger followers, alightweight forged piston and Nikasil coated cylinder.Even on the wet, snowy and very elevated mountain passes around Salzburg, theDuke’s 375cc single could reach 160km/h, at least according to the speedoanyway. I couldn’t get much more out of Kawasaki’s faired twin-cylinder Ninja300.
KTM claim 44hp at 9500rpm from the short-stroke (89mm bore x 60mm stroke)engine with 35Nm of torque at 7250rpm.This is quite a remarkable output from a well-mannered 375cc single that willhappily tootle around town in the upper gears with hardly a grumble. Such arethe wonders of modern cylinder-head design paired with a well sortedfuel-injection system. Those familiar with KTM’s large capacity twins well knowthat EFI tuning was not KTM’s strong suit, with this new Bosch managed 46mmthrottle body KTM have turned a corner, and thank god they have as bad fuellinghigh-compression (12.9:1) road going single would be a defiantly cantankeroussod of a thing.The Duke 390 is instead a smooth running little sweetheart, particularly above4000rpm but much less than that can be used in lower gears without much snatchor complaint. On the highway it happily cruises at 100km/h turning a leisurelyfeeling 5000rpm.Swapping cogs is a joy via an all-new six-speed box and thanks to thatsingle-cylinder torque the Duke jumps off the line eagerly. The throttle actionitself is quite long, perhaps to better help learner riders to smoothly applythe throttle and make for smoother acceleration and on-off throttle commuting.The ratios are wisely chosen and it is easy to keep the little Duke on song.Braking hardware proved up to the job with a 300mm radial-mount single discclamped by a four-piston caliper designed by Brembo and produced under licencein India.
BYBRE is the curious branding. They worked well enough on the launchwith nice progressive feel and a decent amount of bite but the Austrian testroute was run on undoubtedly awesome, but very wet and cold mountain roads, thusthe stoppers were never pressed seriously hard. We did have a go thoughconsidering the conditionsSimilarly, we were unable to accurately gauge Ground Clearance but I suspect thepegs might be a little low for serious knee-scraping nutters. The stoppers bringadded safety to the package via a latest generation Bosch 9MB two-channel ABSsystem, which can be turned off if stunting is your thing.KTM-owned company WP, produce the beefy 43mm inverted forks and matchingmonoshock rear.
Both ends offer a handy 150mm of well damped travel but the onlyadjustment provide is rear preload. Despite the lack of damping adjustment,riders of all sizes praised the suspension of the machine; it is a long way fromthe crudely damped and undersprung crap found on no-name Chinese bikes.Thanks to its light weight and high-performance Metzeler Sportec M5 rubber theDuke 390 is supremely agile while retaining an impressive degree of stability.The 11-litre tank is modest but KTM are claiming 3.4 litre per 100km fueleconomy under the standardised EU testing regimen. That sounds too good to betrue but it is likely the 390 Duke will easily better 200km between fills andoffer frugal, economical motorcycling.KTM Australia’s aggressive $6995 price on the 390 Duke is highly competitive,especially considering the standard ABS. Most rivals charge a $500 premium forthat excellent safety aid, which is of course highly important for the newriders this machine is aimed at.Although at that price I can see plenty of well-seasoned motorcyclists being wonover by the 390 Duke as a second-bike or commuter. It looks horn, goes well,handles well and is great fun to ride.Source.
