Bajaj Dominar 400 Ownership Experience Thread

Re: Bajaj Dominar 400 Ownership Experience Thread

Why does rear axle nut require so much of torque, 100 kg.m to be precise?

I adjusted the chain slack myself and measured the markings exactly in millimeters. As you all may know, it was a tedious process because the chain keeps getting tighter after tightening the axle nut.

I don't have a torque wrench so made some assumptions on how much body weight to put on the spanner. But I soon found out that rear wheel gets harder to spin as soon as you tighten the axle nut lightly. Based on that, I tightened it with medium force.

Then took it to the SVC and requested the friendly mechanic to re-adjust it with a torque wrench. By that time, the axle nut had become loose and he had to turn it a lot to finally arrive at 1000 kg.cm torque figure.

But that definitely tightens the rear wheel a lot, it doesn't spins more than 1 revolution freely by hand. IS THIS OKAY? ( In comparison it was making 2-3 revs by hand with fully opened axle nut).

It only require 9.0 to 11.0 kgm of torque 1 kg m is 9.5 something NM. For unit in cm 1000 seems ok. As for revolutions feeling tight then it could be a over tight chain slack or stuck brake pads. Free hand rotations are not as smooth in Motorcycles now days as it use to be, another factor is that one of the brake pads (inner) on the disc runs in little contact and it is ok.
If it the bolt is getting lose frequently then do get the Axel rod and bolt threads inspected. While aligning the chain adjuster on the rh side hold it in place by hand while tightening the axel so that it remains at its place.

Compare the free hand rotations of wheel with another Dominar sadly i can't do this as i no longer owns a Dominar but yes it was tight same in my current Motorcycle.

Please share some information regarding the tyres, price, small performance review, any other observation.

Got them for 6k, haven't had the chance to test them yet, only ran about 20km. Will post a review in a few days.

I swapped the tyre anyway. Got Apollo Alpha H1.

Cracks at 6000kms seems to early. Get it checked at the closet mrf faast center and they'll advise.

Cracks are showing on the sidewall of the rear tyre. Stock MRF Revz, 6000km run. Does it need replacement?

The tyre also has three puncture plugs, how many are considered too many plugs?

I think you have old model Dominar , from 2019 Dominar is also getting petal disk . So you can buy Dominar disk itself you'll get petal disk itself.
apart from good heat dissipation no other use from petal disk .

You might be talking about the BS6 Dominar 400. I have a 2019 UG, no petal disc.

Re: Bajaj Dominar 400 Ownership Experience Thread

The rear disc of NS/RS which is of same size is a direct fit, but as far as front disk is concerned the only option I could think of is Mahindra Mojo as it's front Petal disc size is 320 mm but am not sure if that gonna fit on the front rim of Dominar.

Btw, can we expect improvements in terms of braking if switched to Petal Disc?

It is a direct fit, but it is a 3.5mm disc. Dom comes with a 4mm disc. Brake feel is greatly reduced after the swap, first hand experience.

Hi guys ,
Regarding my query - Point 2 - Tank range.
My last 2 full fuel tank ranges are back to 390km + . Don't know how. I have even got a range of 423km displayed on my console.
Last ride of 220km gave me a FE of 34kmpl. (Pic attached)[ATTACH]256200[/ATTACH]

With speeds varying from 60-90kmph

Re: Bajaj Dominar 400 Ownership Experience Thread

Hi Everyone,
I am a new user on xbhp. I own a dominar 400 2019 bike. It has completed 1 year of running. Can I get some help on the following issues/things I have noticed recently on my dominar.
1. RPM Fluctuation - how much rpm variation is ok at idle. I feel the RPM Fluctuation is noticeable. If put on a paddock stand and 1st gear engaged the speed varies from 8kmph to 11kmph. Is this normal?
2. Fuel Tank range - From past 4 , full tank , my km range is not going above 350 - 360 Kms. Earlier on full tank I was getting a Range between 395km to 411km. What could be the issue.
3. I asked the service centre to update my speed console , so that I can get the gear indicator on the primary console. Is this update stable? Or I should not get it done?

Thanks
Jayant

No If you swap with right size no changes required, But suggest you to change pads once you change disk.
Usually old pads would have rubbed against old disk and if old disk has developed a pattern of of your old disk due to continues rubbing.
I mean old disk would have different pressure points where it has reduced and forms a ring pattern.

Thus with new disk the pads with pattern can impact new disk , Else sand it and use old pads if they still have more life.

Guys, does swapping standard round disc brake plates with Petal disc on our 2018 Dominar requires and alterations of stock brake pads/calipers?
