Default Tyre pressure for Electra (UCE)

Hi all,

Couple of weeks back I have taken the delivery of Electra (UCE) 350 and I am quite happy with that.

But I always feel that, when I take turns, bike is not stable and looks like it is wobbling at the back .

I am maintaining the tyre pressure of 25psi at front and 35psi at rear.
When I asked the royal enfield showroom guys, they said that
it should be 20 to 22 psi at front 28 to 30 psi at back.

But I am not sure about it. As a habit I used to fill 26 F,36 R always for my HH ambition and RK.( Both are sold now anyway) and so I am doing almost the same for the bullet also.

Bullet experts, Please through some light on this.

Thanks.

So even the Electra UCE has this problem!
LOL, looks like Enfield will never learn about designing and engg.
But its got nothgin to actually do with tyre pressure.

Anyway Reduce the pressures on both tyres - 20/30 psi (front/back) - as rightly said by the Enfield guy.

25/35 will make it too hard and bouncy.

F -22 & R -30 is what I find comfortable on the TBTS.

The thing with enfield is that they do not update their manuals properly.
The manual still has the tyre pressure from the days of good ol' bullet.

UCE Electra is much lighter as well as has a different set of tyres.

I remember the recommended pressure in my TB given as 25/30.
that makes it too hard in the front, and too squishy at rear.

Dear Alpha,

Do you mean to say that, old electra 5s also has this problem.( or/and even TBTS).

I dont know about this.

Anyway thanks for your suggestions, and thanks for all of you guys for your time and reply,

I will reduce my tyre pressure and try.

or Is it to do anything with tyre.

It is coming with Dunlop but I was expecting MRF Zapper

If you are running stock tyres, I would suggest:
22psi on front and 32psi on rear on dry roads
and 20psi on front and 30psi in wet conditions.

I have tried the same on my UCE Electra and found this to be the ideal pressure.

Also, fill air only when the tyre is cold and not after a long run.

Stick to one tyre shop and fill it from there. Make sure the guage used is properly calibrated since the guages used by road side shops usually indicate lesser pressure than it actually is.

So, if you fill upto 35 psi, it might be as well as 37-38psi, which is quite high and the contact patch reduces, and you will get the wobbling effect.

Better still, buy a good quality pressure guage, should be around 150-200 Rs., and check the pressure yourself.

Learn to use it properly though, or else, you might end up letting out the air in the tyre.

Both brands are inadequate for grip in the wet, but Dunlop tyres provided on the Electra are better than the MRF Zappers, in my experience.

I maintain 22 psi for the front and 32 psi for the rear.

Play around in this range and you will eventually hit the sweet spot.

I used to keep 25(F) and 35(R) pressure. But now my mech says I need to keep 35(F) and 40(R). BTW I ride an electra 5S CI.

I have always found that greater the tyre pressure less the wobbleness.
I put 26F and 36R in my thunderbird.

I know that is way above the recommended psi levels but 2 things I find has improved with this.
1. Beter mileage
2. Stability.

Just my 2 cents.

Hi,

The right pressure for Single rider is 20F/30R and with pillion is 22F/30R. The tyre wobble is also due to mis alignment of the wheels. Get the rear wheel aligned\chain adjust and it will be just fine.

Hi all,

Even the tyre pressure change(20F/30R) did not do for me.
Finally I took it to RE service station JP nagar, and when I said this issue,
he Just said that wrong tyre pressure

Then I had to explain him, that I have tried all combinations , even then there is wobbling.

Finally He took out the wheel and checked , found that there is misalignment and tighten/adjusted the couple of spokes, now it seems like it is OK. But I need to wait and watch for atleast a week.
