Hi guys,
I was curious what advice you had on reducing engine braking on a KTM. My thought was maybe this is something Tokyo Mods could help with? Would a flywheel weight help? Thanks in advance!

I think the best bet is a remap or a vortex.
You could mess with gearing but that changes everything.

I’m pretty sure the KTM Wi-Fi tuner has a function where you can adjust engine braking.

Turn up the idle. I think manual calls for 2300.

I always run my throttle housing forward, and no slack in my cable. Engine braking never an issue.

Keeps the throttle open slightly by just holding onto the bars? Doesn't seem like a great idea.

The tech that builds the bike just attaches the throttle housing to the bar. I roll mine forward to fit my wrist and riding position. This adjusts the idle to full throttle position, keeping my wrist in the proper position. Reducing fatigue and arm pump. Taking the slack out of the cable, puts idle at the top. Power requires less movement, and is immediate. Again keeping your wrist/forearms in the strongest position.
With the controls rolled back, this puts more pressure on your wrist and forearms. Your wrist is now bent in the idle position, and weakens when rolling on the throttle. Causing undo fatigue on the wrist and forearms. Add 2-3mm of cable slack. When I am rolling off the throttle my RPMs are always higher reducing the engine braking.
Easy and no cost fix.

If your throttle is fwd or back or upside down, it doesn’t change the position of cracking the throttle. Silly

Placebo effect can be very strong. But if you believe in your head that it works, that's all that matters !!! Smile

For sure. But ECU mapping is the best way to reduce engine braking. I’ve heard of some riders raising the idle 1/4 turn so the drop off when chopping the throttle isn’t as harsh, but there’s a limit on how much you can push that.

Basic. Housing at 1 o'clock engages before positioned at 11 o'clock. Cable tightened so that idle is at the start engages before a cable with 2-3 mm of slack. No placebo effect. Fact. If you have poor throttle control, this may not be a good option. This effects the engine braking. The engine brakes/slows due to reduced rpms, with hosing position and a tightened cable, your rpm rate is more consistent. Bonus is less wrist bend, stronger position and reduced arm pump.

I can’t see how moving the throttle from 1 o’clock position to 11 o’clock will change the throw? You can change cams on throttle which will effect the opening of the throttle.

If you open and peanut butter jar with the label facing you, then open it with the label facing the wall. Won’t it take the same amount of turns to remove the lid?

Sorry just trying to wrap my head around this?

1/4 turn is 1/4 turn no mater where you start and finish. It’s where your hand starts the turn, not the housing. The only thing rolling the throttle forward does is change the orientation of the grip in your hand. This can help if you run a half waffle and are picky on where the extra grip lands in your hand.

Turn up the idle. I can shift from first thru to fifth and just idling will pull each gear on my mc450

Removing slack gives you immediate engagement. Every mm of slack delays the power delivery, and increases the engine braking during roll off. It takes alot more throttle control. Housing is hand position. Putting your wrist in the strongest position. Rolled back with slack puts alot of stress on the wrist and forearm. Personal preference. Remapping changes the delivery at a rpm rate. You first have to engage. Immediate or delayed. Try. Quick and easy. No cost little time.

Rolling the throttle housing backwards does not change the play in the cables, nor does it affect the engagement of the acceleration or engine braking. (Unless, perhaps, if you rolled it back so far that the cables were stretching around the handlebar a few times.)
To get the effect the poster is mentioning, one would have to reduce the play in the cables so the butterfly opens up sooner (and stays open just a little). You could get the same effect by increasing the idle.

Here's my best advice for reducing the engine braking:
1) Remove the gas cap.
2) Roll a 2-stroke underneath.
3) Reinstall the gas cap and enjoy.

Love the peanut butter analogy. So lets try that one. The jar is closed facing the wall. rotate the jar clockwise to 1 o' clock, the lid will be removed before the jar rotated at 11 o'clock. Now how this would effect rpms. Slack or not, hand position.Turing the throttle in the forward position opens the rpms/jar quicker, and keeps the rate longer when closing. Slowing the rpms causes engine braking. This does not effect the idle. No idle adjustment is made. My other ride is a 2 stroke.

Having less slack can make a difference on how much you have to twist the throttle, but how it is clocked on the handlebars makes absolutely no difference.
