Bajaj Dominar 400 Ownership Experience Thread

Re: Bajaj Dominar 400 Ownership Experience Thread

Can't we use the stock ABS line when swapping the brake hose?

Yeah. Also what was the reason for the swap.

Yeah. Also what was the reason for the swap.

I had a look on Amazon and AliExpress and found some inexpensive Steel braided lines. I thought I'll take a chance on them. I've heard from the ASC that the pulsar 220 hose won't fit the Dominar, so I started looking elsewhere. I feel like the current setup is too spongy for my riding style.

Bikes equipped with ABS will have spongy brake feels. The entire force will be transferred to the module first then to the caliper. Upgrading to steel braided lines won’t make much difference.

Thanks for the info. I think I'm lacking research on my part, I'll see what can be done apart from brakepads.

Yeah. The brake fluids too play in increasing performance. Also D400 have steel braided lines I think. Rear should be rubber. That’ll help a lot.

Re: Bajaj Dominar 400 Ownership Experience Thread

Had anybody tried to fiddle with the Dominar's OBD port and ELM327 obd scanner?... just saw in youtube that somebody had successfully communicated via bluetooth to the torque app using this device but it is not very clear which colored wires from the dominar are for what.... I am certain that the black yellow strip is the batt neg and the gray one is batt positive, however am not sure about this two:

blue wire: CAN high? ECU positive
Yellow wire: CAN low? ECU negative

I am afraid if I get the connections wrong, it might fry my ECU?

Is there any free camshaft replacement for the UG Doms that have engine knocking ?

I saw your older posts also, you haven't indicated which version of Dominar you own. If you have the one with dual ABS then I am pretty sure that all brake hoses are steel braided only. And we can't make any changes to it, it's already at its best performance. What you call "Sponginess" is actually modulation range. I have had the problem with spongy disc brakes since a long time, spongy feel means you have to apply too much pressure on the brake lever and you get very low braking pressure on the disc pads comparatively.

Whereas in Dominar (at least in new ones like mine) I can see that its easy to judge it as spongy since the brake lever action is LONGER. Also, most of Dominar owners upgrade from <200cc motorcycles which had simple front disc brakes and we instantly start comparing Dominar's brake FEEL to them. But I have tested it extensively and determined that it is not spongy at all, just that it allows greater range of lever action BUT delivers proportionate braking pressure regardless. I was testing the ABS effectiveness while braking on a road with lots of fine sand! And I found out that in such extreme conditions, its better that I had a greater lever range which allowed me to modulate & adjust my braking pressure with greater confidence.

ON THAT NOTE, I was grinning ear to ear after finding out that the ABS performs flawlessly under extreme conditions, I slammed the brakes hard on roads full of sand/mud at high speeds, but the brakes performed AS IF the tyres were running on sticky tarmac! I couldn't detect the tyres slipping at all, it just stopped smoothly in a straight line. And I keep testing it whenever I find sand or mud on road, it always performs exactly as expected.

If your bike is more than 1 year old, then you can opt for brake fluid bleeding, it will remove the air bubbles from the lines. But I have only done it in simple (non ABS) brakes, I guess it would become a tedious chore in case of ABS because of long and twisted brake hoses.

I have a 2019 UG, got it in May last year. Even though this is my first proper motorcycle, I can comfortably say I'm "used" to it now, after 10 months of use. Also, direct brake feel is not what I am referring to. Even though the brake feedback is progressive, there isn't enough initial bite on the front. The rear is just pathetic, it's not even reliable. I've ridden bikes from Royal Enfields to KTMs, and none have this bad of a brake on the rear. The front is still a different story. Under hard braking, it stops better than most bikes in this segment and ABS is non intrusive, works flawlessly. But riding in traffic, you wouldn't want to keep pressing your lever hard just to get a little bite. I started looking at upgrades due to this. I live in Bangalore, and I have extremely long traffic holdups. All I'm trying to do is make the traffic ride as less of a pain in the butt as possible.

ABS brake bleeding on dominar is as easy as usual bleeding. No actuation of ABS system is needed.

Yes, it is same as non ABS process. All you need to do is turn off your ignition. Then do the bleeding process.

Re: Bajaj Dominar 400 Ownership Experience Thread

Today i did a short high speed ride of 40 to 50 kms....... Experience was shaky bumpy and wobbly....... Why so.? Need an advice
Speed maintained like 120 to 130 kmph some times near top wack of 170kmph

Re: Bajaj Dominar 400 Ownership Experience Thread

I've been plagued by this issue from the time of taking ownership. Coincidentally mine is a May 19 purchase too. Does this conclude that May 19 batch has this problem ? Are any other owners from the same month experiencing a similar issue ?
I'm tired of this problem and its pushing me towards selling off my motorbike.

I have the same issue and mine is from the June 19 batch. I thought it's because of the stock MRF tyres and was thinking of upgrading.
