Re: Hero Karizma ZMR (2014 version)

Can I get those wheel weight...I inquired at my SVC..but they do not have

Re: Hero Karizma ZMR (2014 version)

thats strange !! have you inquired about it to the svc - should'nt the wheel have the balancer !

Re: Hero Karizma ZMR (2014 version)

There are some random noises from the engine and does not feel as smooth as a zmr should be. But It's running fine. No major issue. So, I am not too bothered about the engine as such. There is so much to life than that one thing. But there's a chain issue lingering since 5 months now. Aiming to get it sorted in a month either by repair or replacement.

Re: Hero Karizma ZMR (2014 version)

Bro,How is your 2014 zmr doing bro? Are your issues relating to engine solved? How is the performance after year & half of usage? Waiting in anticipation for your reply. Ride safe.

Re: Hero Karizma ZMR (2014 version)

Never had any balancer on my wheels. Neither from the factory ones nor on the ones I replaced after the bent.

thanks a ton !

Re: Hero Karizma ZMR (2014 version)

The pic you shared of the classic ZMA having 2 weights is most probably additional weight attached 'later' at a tire shop. All Karizmas come from factory with one weight per wheel only.
Alloys are either made of Aluminium or Magnesium. Karizma has Magnesium alloys.
Die casting is a process where molten alloy components are forged into the casting chamber at high pressure. This ensures increased structural rigidity and uniformity over non die cast applications.
AZ91D is the most commonly used Magnesium alloy for die casting.

Thank you God . Really you are a true God ! . But one thing how come in the zma it has 2 wheel balancer and in mine R it has one - I know it is how the engineer have designed it but why there is 2 in zma and 1 in R ? - And in the manual its says our wheels are die-cast - what is it ? - is it alloy or some other material being used like Fe.

A wheel comes balanced from factory. This may or may not include the small weight attached to the rim.

Based upon the usage pattern, this default balance goes for a toss.
The problem is unequal weight developing on the rim of the wheel or tire.
As the wheel turns, spinning forces exaggerate this imbalance and make the wheel oscillate at speed, like an old fan. This can be felt as loose or wobbly steering at speed and harsh vibrations.

As the wheel tries to wobble itself out of alignment, vibrations make their way through the wheel spindle, which in turn stresses the wheel bearings, leading to premature wear. There’s also the danger that excessive vibrations could loosen various fasteners around the bike. Tires will also run hotter as the contact patch squirms and this leads to uneven wear.

Balancing the wheels is hence is necessary and remarkably easy to do, albeit not well versed with the mechs in India. The idea is to counteract the weight causing any imbalance by adding more weight directly opposite the heaviest point of the wheel to counter-balance it. Attaching small weights to the rim, where the effect of centrifugal force is greatest, achieves this.

These weights usually come as 5 gm and 10 gm units and are stuck to keep them in place. Classic bike owners prefer lumps of lead/solder wrapped around the spokes. Motocross wheels are very rarely balanced as they use security clamps in the rim to hold the tire on which are virtually impossible to counter-balance.

How to correctly balance the wheel:
P.S - To balance a wheel, you must first remove any existing wheel weights from the rim.

1. With the wheel set on the balancing machine, position the air valve at the very top and gently spin the wheel – not too fast, but with enough force for the wheel to complete four to five revolutions. If too much force has been used, one can slow the wheel down by applying finger pressure on the tire.

2. When the wheel comes to rest, mark the position of the lowest (technically, heaviest) point of the wheel with a piece of chalk. We'll call this 'point A'.
Now, with the wheel in the same position, mark the highest point of the wheel – this is the lightest point, or the ‘counter balance point’ .We’ll call it ‘point B’. Take one 10 gm weight (available online/tire shops) and place it on the rim at point B – secure with tape only, as you may need to add or remove the weight.

3. Set the wheel with point A at the 3 or 9 o’clock position and let go (don't rotate). If the added weight at point B goes back to the top, and point A back to the bottom, you need to add more weight – say 10 gm – to point B and repeat the procedure. If point B goes to the bottom, you need to reduce the added weight.

4. This is achieved when, if point A is set at 3 or 9 o’clock, it doesn’t move. Once you have got to this point, gently spin the wheel so it spins 2-3 revolutions. When it comes to a halt, point A should be in a completely different position to where it was originally. If unsure, spin the wheel again. If successful, you’ll have a balanced wheel.

5. Remove the tape holding the weights in place and wipe the wheel rim at point B clean using any cleaning agent, and attach the weights (they sometimes come with a self adhesive back surface. If not, using an industrial adhesive is advised). Tap gently in place with a hammer for a secure fix. If the total added weight is over 25 to 30 gm, divide the weight equally and place either side of the rim.

I hope this answers your question @Dipan12.

Re: Hero Karizma ZMR (2014 version)

Cool, thanks for the info .

Re: Hero Karizma ZMR (2014 version)

First of all. No Sir!! Well.. I am really not sure.. But from what I understand, the wheels need balancing.. Some wheels don't require balancing and some do. Those seen on the pic are weights.. They probably weigh 10g..

Re: Hero Karizma ZMR (2014 version)

Sorry for the noob query sir, what exactly does it do and why is it not found on every bike??
I mean my cousin's shine has it but my R15 doesn't. Why so??

Re: Hero Karizma ZMR (2014 version)


That is wheel balance..

Re: Hero Karizma ZMR (2014 version)

WHAT IS THIS ? TWIN ? I have one in my wheels .

Re: Hero Karizma ZMR (2014 version)

Thanks a lot . In case of reduction of performance will pickup gets hit ?
