I had used RC for 12k kms, coming from an R15 I always felt lacking initial bite and feedback in the RC. The stopping power was there and I felt safer during emergency braking, but it was difficult to modulate, feedback was not good and the abs was kicking in too early than I liked. After some usage I got used to it. Although its okay a little more bite and feedback will make it better.

If the dia of the piston in mc is more than stock mc it will definitely increase the pressure and will reduce the rider's effort, but there wont be any major change in stopping distance and the feedback won't increase. In RC the real culprits are the pads, changing the pads to ebc sintered ones will make a major difference both in stopping power and feedback. The pads cost around 3-3.5k and will make significant change in braking performance than a change of master cylinder.

Change to bigger steel braided brake lines, I did on my non abs CBR 250r the bite felt Like 10x stronger and better. These brake lines I have are from Thailand, very good make ,

What happens if you do that :
1. The volume of those two pistons will always be lesser than that of four used together
2. The deceleration which four piston offers is anyday way better than two piston arrangement. though it may lack initial bite (which i feel is compensated in overall distance of stoppage) but instant decrease in speed is better in former one.

sorry if it sounds offended but regards to the experiment, its straight from Horse mouth
but technically, this is not possible. The pressure would be increased only if either the master cylinder piston is reduced in diameter or the lever is pressed with more force (simple law of hydraulics)
Pressure at MC
yes the initial bite can be felt better because of the increased diameter (thanks to increase oil flow)

It may not sound amusing,
Even if you place Bajaj Calliber's MC to it, changes will be there
But the million dollar question is : Is the change tending to have tangible benefits ?
1. Just try measuring stopping distance and it will tell you the real story
2. time to decrease in speed from application of brakes (e.g. 100 - 40kmph)

No offences but my two cents..

The stopping power has not increases, but the feedback and the bite coming early, I can predict how much press of the lever will produce how much stopping power which the default MC lacked.

The video is not mine but another guy who made the same change

Re: KTM RC 390 Ownership Experience

im not sure about the stopping power, but definitely the bite has increased and just the dab at the lever actuates braking which was absent before.now i can safely brake with one finger! Im again telling you there is a considerable difference, almost did 100 kms inside city and felt it better.i almost forgot, front abs actually acts under braking with this caliper which was absent in stock caliper.

Guys
Can we install the new fairing from the 2017 ver or are the mounting points different on that one?

All the same. Mounting points are same except the lower part which holds the exhaust.

Guys any clue if we can fit the bigger discs on older RCs?

I think its possible, there was a 320mm disc (powerpart) for RC390. Maybe we have to use different spacers at calliper mounting.

Thanks bro
Guess I'm gonna buy the new fairing and change the look whenever I want

What about you guys?

Please do remember to share the costs of the panels. Probably few weeks are required before new panels show up as spares in the service centre.

Most, if not all the existing changes in the RC can be done to the existing RC breeds. All it requires is a skillful, and patient mechanic. The changes aren't radical as opposed to the naked series. But, discs, levers, and nitty gritties can, for the most part be swapped.

Re: KTM RC 390 Ownership Experience

Any pointers on how to exactly measure handlebar alignment on this bike? Bike has disbalanced and fallen twice in stand still position.
Also is it normal for the RC to switch on the fan within 15 mins of riding in bumper to bumper traffic whereas bike was parked for 4 hours before riding?

To your first point, first make sure you don't have a bend. There are many things that can go wrong in the naked 390 in case of a handlebar misalignment, on the RC it's either a bent clipon or a warped top plate. Loosen the T stem nut from the steering stem and adjust and see if it solves the problem. If you find difficulty, take it to the SVC they can do that for you.

Secondly, yes 15 mins of B2B is more than enough for the fan to kick in, irrespective of if the bike is parked for more than four hours or a day.

How does the bike behaves at our desi crusing speeds say between 90-110? What's the rpm?

100kmph=6000 rpm which is also surprisingly the most vibe free spot on the 390.

The torque pull at 7.4~ RPM is something to be experienced by everyone. Just the urgency and the lunacy with which this thing pushes you towards the back of the seat, you should read close to 130+ on the 6th cog. Downshift a gear from sixth and open her up, she becomes a different one altogether.

Now, any speeds above 110, a good road and a confident inspiring mindset works wonders. But being spatially aware, being constantly alert, especially on deserted highways, because you never know what can hop out of nowhere, be it a crater or an animal or a human, worse.
