TELESCOPIC FORK

The KTM RC 390 high-quality upside-down fork from WP Suspension has the same 43 mm outer tube diameter as the RC8 R – in other words, real racing equipment that guarantees highest levels of stability and precision.

FRAME

Visually similar to the lightweight and approved Duke steel trellis frame, the orange painted frame has been modified to better fit the supersport ergonomics and dynamics. The increase of the steering head angle to 66,5 degrees results in a shorter trail, shorter wheelbase and increased ground clearance. All these modifications release the complete racing potential of the RC and guarantee quick, agile and playful handling.

INSTRUMENT

The 100% digital LCD display has everything you could expect from a state of the art KTM motorcycle, including engaged gear, fuel gauge and service reminder information. Just like supersport racing machines an RPM alert indicates when is the best moment for shifting up.

SWING ARM

The light alloy swingarm with directly linked WP shock absorber excels by providing extreme torsional stiffness and outstanding tracking stability.

WIND SHIELD

The advanced design wind shield in combination with the aerodynamic optimized motorcycle front ensure incredible wind protection for rider’s chest and arms.

SEAT

The two-part seat offers first class supersport ergonomics with perfect support for rider and pillion. With a seat height of 820mm it enables the rider to have a secure stance whilst also being high enough for sporty use and real big-bike feeling.

FUEL TANK

A brand new steel fuel tank with 9,5l capacity (including 1,5l reserve) has been developed for the RC, perfectly matching the supersport style and vehicle design, together with rider ergonomics. Thanks to the economic engine the RC achieves impressive efficiency even when ridden hard for a considerable distance.

HANDLE BAR

Brand new clip on handlebars and switches contribe to a sporty and aggressive riding position combined with advanced control.

WHEELS

Equally lightweight as stable, the 17in orange painted cast light alloy wheels are fitted with grippy Metzeler tyres – 110 mm wide at the front and an impressive 150 mm at the rear. The tyres impress with tremendous grip in both wet and dry conditions, as well as providing supreme durability.

STANDARD ABS

ABS is equipped as standard on every RC 390, ensuring maximum safe on any road condition. When taking the RC to the racetrack ABS is of course disengageable.

SILENCER

The compact underbelly, three-chamber silencer is positioned close to the bike’s overall centre of gravity. This aids the centralisation of mass and prevents accidental contact with the rider’s and passenger’s legs.

A2 LICENSE

With a power/weight ratio of 0.2kW/kg RC390 is right at the limit of the new A2 driver´s license, making the new KTM RC390 the sportiest option for A2 riders.

THIN TAIL

Fitting perfectly into the pure racing look the number plate holder rounds KTM’s high performance bike off.

BODYWORK

The brand new bodywork, footrests and pedals not only provide a unique supersport look but also help the RC to master extreme cornering by allowing a greater leaning angle.

INTEGRATED BLINKERS

As a special feature the RC incorporates blinkers into mirrors structure, which not just looks very sporty but also contributes to the perfect aerodynamics.

HEADLIGHT

Brand new twin headlight opens a new direction for KTM style and perfectly matches with the racing supersport look of the RC.

ENGINE

The state-of-the-art, liquid cooled, single-cylinder four-stroke 375ccm engine with twin overhead camshafts, four valves and electronic fuel injection, already equipped in the Duke 390 provides outstanding power and thanks to the balancer shaft, delivers the highest level of smoothness. Because of the KTM-typical compact design with stacked transmission shafts the engine has an unbelievable low weight of 36kg. Combine that with technical details like a forged piston, Nikasil-cylinder-coating and forced feed lubrication with power-promoting body-evacuation and you get an engine which provides a remarkable 44hp. The engine is equipped with an electric starter powered by a 12V/6Ah battery.

TRIPLE CLAMPS

The brand new forged aluminum triple clamps are eye-catchers and together with the clip on handlebars guarantee a pure supersport racing feeling.

PILLION RIDE SEAT

In order to make no compromises in terms of supersport look the KTM engineers integrated the pillion seat into the bodywork lines so that it looks like a real racing bike tail, but ensuring excellent comfort for the passenger.

BRAKES

KTM developed in cooperation with Brembo a powerful and easy to control brake-system which allows the rider to be always in control of the RC. A four piston radially bolted caliper in combination with a single brake disk (300mm diameter) in the front and a single piston floating caliper with a single brake disk (230mm diameter) for the rear wheel guarantee excellent braking response even under the most extreme conditions.

should be good enough
1 cylinder machine mah

1 cylinder high torque ma, later kapcai overtake.

Kapchai can overtake 43hp?

Your torque will run out very quickly at high rpm, you can take the lead, over time you suddenly see some rempit coming from behind.
Why don't you go and test?

There are reasons why people take 2, 3, or 4 cylinders.
1 cylinder isn't gonna cut it if they're trying to sell based on its looks.

Design like this I was hoping around 14-15l

What I'm saying is, if they put 1 cylinder, don't design that looks la.
People not well versed in the specs might expect something else out of it.

boleh bawak awek tak moto ni.. mcm 1 seat je.

It's stated that they designed the pillion seat to look like it's not there, to make the bike look like a 1-seater.

So I guess boleh bawak awek as long as she's not huge like rosmah.

Can't lili brain what u r spewing..... can u speak in layman's term. X paham siall.

There r so many factor that affect a bike's performance. Cylinder count is just 1 of tiny weeny of them.being a thumper ain't no joke bro. It being a single cylinder, but at 390++cc, no moped can come near it, performance wise...

itu la aku tny die
moped mana / kapcai yg boleh kejar 44hp bike? hahaha

bang, x pernah ride KTM yer?

not ride both, but i never see ktm cilok like ex5

is RC125, RC200 RC 390 going to have the same look?

Same look, not very sure bout the sizes.

all 3 models 125/200/390 use the same chasis
so size wise should be the same
only the engine is bigger

Hmm okay interesting.

Wheel size also same?

wheel size sume same 17
hahaha lebar tayar je lain

Haha!

Eh Duke 390 is about RM28k kan? So I guess this one should be around there too?

Haha!

Eh Duke 390 is about RM28k kan? So I guess this one should be around there too?

Meh.

Single cylinder.

Some more ketam now manyak faggot owner especially those former rempit

Single silinder ok wat, i used to own suzuki fxr 150,
Really powderful dohc engine,
Big tank, can full throttle from penang to sepang, pusing pusing summore without refueling.

Top speed around 160-170kmh..

This bike sure doubles the fun!

Wowow is it coming to MY?  This is wot I wanna ride if I finally decide to learn to ride bikes.

ok or not if get the rc390. fits the budget.

FXR 150 is different kind of beast, can never compare with lowly indian-made motorcycle with austrian logo badge on it

by end of year or early 2015
the RC390 will be around 26K, so OTR probably 30K+

my modenas kriss modified already top 160km/h. modified sikit lagi boleh tapau moto ni.

ktm rc200 and rc390 sudah launch semalam

RC390 price?

28K OTR

better take CB 500R

bape torque RC390?
cakap macam minyak punye kapasiti tinggi torque tinggi? ahahahah
ni spec die
KTM RC 390 43.5 bhp and 35 Nm Torque. 373.2cc. Top speed - 175 km/hr.
kawasaki kips 150 rr tu pun baru 20+ Nm torque
sumber kalau tak percaya boleh google

seriously
cari 1 kapcai
yg kuar2 kilang boleh lawan 390cc 44hp
i had used so mana moped
mana boleh pegi 180+?

Banyaknya yang mempersoal tapau-menapau sesama motor. Jadi aku akan explain dari segi engineering (ambik elektif dulu automotif engineering):
1) Torque determines the acceleration.
2) Horsepower determines the top speed.

acterly this is already wrong concept.

power is produced by torque on a rotatating shaft. so  power = torque (x a constant) when the shaft is rotating

there is no such thing as max torque = max acceleration, which occurs on a fix ratio gearbox.

more so when you throw in a CVT into the concept then max acceleration occurs at max power, not at max torque.

boleh bawak awek tak moto ni.. mcm 1 seat je.

The other interesting thing about the KTM design of the RC200 and RC390 is the implementation of the rear seat to make it looks like a single rider bike, but actually the one that is looking like the rear tail cover is actually a soft plastic with padding to function as a seat. Clever!

power abang nie..

kalau nak speed 299 HP moto kena  ada berapa ?

acterly this is already wrong concept.

power is produced by torque on a rotatating shaft. so  power = torque (x a constant) when the shaft is rotating

there is no such thing as max torque = max acceleration, which occurs on a fix ratio gearbox.

more so when you throw in a CVT into the concept then max acceleration occurs at max power, not at max torque.

Torque is the rotating force along a shaft, it is translated back into translational force by the wheels.

This is why a Silvia S15 has faster 0-100km/h time than a Honda S2000, both have about the same weight and horsepower. But the force exerted by the wheels of the Silvia is larger than the S2000 (because of higher torque), thus it accelerates faster. Remember F=m.a, so a = F/m

Your torque will run out very quickly at high rpm, you can take the lead, over time you suddenly see some rempit coming from behind.

Banyaknya yang mempersoal tapau-menapau sesama motor. Jadi aku akan explain dari segi engineering (ambik elektif dulu automotif engineering):
1) Torque determines the acceleration.
2) Horsepower determines the top speed.

Dua-dua mempunyai hubungan:


Ini basic untuk torque dan horsepower. Lepas tu:
1) The lighter the vehicle, the faster it accelerates. The heavier the vehicle, the slower it accelerates if both of the vehicle have the same torque.
2) Vehicle with higher air drag will have lower top speed, vice versa for both vehicle with the same horsepower.


FD is the drag force, which is by definition the force component in the direction of the flow velocity,[1]
rho is the mass density of the fluid, [2]
v is the velocity of the object relative to the fluid,
A is the reference area, and
CD is the drag coefficient – a dimensionless coefficient related to the object's geometry and taking into account both skin friction and form drag.
http://en.wikipedia.org/wiki/Drag_equation

Untuk hubungkan drag force sama horsepower (untuk overcome the drag force at high speed):
P = F.V
P: Power
F = Drag force
V = vehicle speed

Dari formula drag force boleh lihat drag force increases exponentionally dengan peningkatan vehicle speed, sebagai contoh:
Katakan drag force untuk 50 km/h = A
drag force untuk 100 km/h = 4A
drag force untuk 150 km/h = 9A
drag force untuk 200 km/h = 16A

Macam mana dapat 16A untuk 200 km/h? Bahagikan 200 kuasa dua sdengan 50 kuasa dua = 40000/2500 = 16

Sebagai contoh horsepower kereta dengan top speed yang boleh didapati:
100 km/h = 20hp
190 km/h = 110hp (god car, waja, honda siti nurhaliza)
260km/h = 280hp (subaru imprekzaaa, lancer evo ori, lancer evo tiruan wiralution)
410km/h = 1000hp (veyron)

Boleh nampak semakin tinggi top speed, gila vavi horsepower diperlukan.
Jadi kapcai dengan 9hp mahu tapau KTM 390 dengan 44hp, jangan harap lah! lol 
kapcai yang sudah gila babi modify pon boleh cecah 160km/h jek.
Satu-satunya kapcai yang boleh lawan ialah kapcai 125z cub prix, ini gila vavi laju.

ah but what if you change the final drive ratio to the rear axle.. now that changes your acceleration doest it..? why cos input RPM to the rear gearbox axle is higher, output is lower.. hence producing more torque.. hence producing more power, so accelerate faster.

remember, dyno shows results in power, but all it does is measuring force acting on a drum at known RPM.. at the end you can say torque and power have linear relation ship..

If you change the final drive ratio, you changed the rpm & torque produced. But power only affects the acceleration at higher vehicle speeds because at high vehicle speeds the aerodynamic drag is pushing the vehicle back.

Dyno shows results in power & torque, check back the charts.

Refer to the equation I posted before, torque and power isn't the only parameter, you have to factor in rpm.

If you want to see the effects of torque and power, you have to set the other parameters to be the same:

Checking the effects of different torque values:
1) Both vehicle A & B have same weight, same horsepower, same aerodynamic drag (same shape). Vehicle A has double the torque than Vehicle B.
Results: Vehicle A will accelerate faster to top speed than Vehicle B but both will have the same top speed.

Checking the effects of different horsepower values:
2) Both vehicle A & B have same weight, same torque, same aerodynamic drag (same shape). Vehicle A has double the horsepower than vehicle B.
Results: Vehicle A will have higher top speed than Vehicle B, in addition, vehicle A will accelerate faster than vehicle B because vehicle A have higher rpm (check back the power to torque equations, with the same torque value, higher power means rpm must be higher). This is simply because when the vehicle A have higher rpm, it can hold on to the gear longer than vehicle B. When vehicle A is still on gear number 2, vehicle B already shifted to third gear and have to accelerate with lower torque even at the same speed as vehicle A.

ah but you are giving the example of 2 same vehicle with double the torque and same horsepower and example 2, double horsepower, same torque.. 
might as well compare,  proton with porsche..can conclude with certainty which one will sure win the acceleration test.

why dont you say 10% difference in torque and horse power, but different gearing/gearbox which will affect the outcome differently.

as i said, in a conventional ICE, max power comes at 6-7k rpm , at 3-4k rpm max torque level, you dont get full power., hence you wont get full acceleration.
if you got a gearbox that lets you rev to max power sooner, and stay there.. then if both cars with same horsepower+torque, the one with the gearing advantage to let you do so will accelerate faster.
