Re: Slippage of tyre Pulsar 220F

Bang On!!!Sharan.
I used it for a while,sadly I had to sell it off while I was switching job/city. Still hunting for a new bike that could replace an all rounder like ZMA.

Re: Slippage of tyre Pulsar 220F

Old Pulsars had a tendency to lock the wheels with the slightest touch at the lever due to uneven force supplied on the brake assy. They used KBX systems then. Later, Bybre units (a bettered version, and to show off by saying it's Brembo's sister concern) improved upon the previous units. Bybre units are good, however not as trouble free as NISSIN units.
RTR series uses Gabriel units (with Bosch ABS) and they're in a league of their own.

Off topic: Have you owned a Karizma ever? Just that your ID/handle made me think so!

Re: Slippage of tyre Pulsar 220F

Sorry Sandeep, I have never ridden either bike, so i am not the best to comment. I have never ridden a bike with ABS,in fact I am eagerly waiting for RTR200 ABS.

But the feel on P180 might be similar to old P200/P220 as the front fork and disc brake dimensions are same.

If you are asking which amongst P180 and RTR 180 ABS is better/safer in terms of braking, then RTR180 ABS is a no brainer choice.
Theoretically, any bike with ABS wins over a bike without ABS in terms of safety, as the probability of wheel locking is very less. Specifically, in case of a bike with Dual channel ABS like RTR180 ABS.

Hope this info helps.

Re: Slippage of tyre Pulsar 220F

Could you put some braking info about Pulsar 180 and Apache ABS ?

Re: Slippage of tyre Pulsar 220F

Just came across this interesting thread....

I will not be surprised if someone fell down from a pulsar after panic braking.And this is not uncommon...Please excuse me if i sounded harsh.

One can owe it to the heavy front and strong,non progressive front brakes(and to some extent bad/hard tyres as well) in comparison to that of Hero,Honda or Yamaha's.
Which will easily cause tail wagging (if 70:30 is not used) and thus lose grip. Unfortunately, the dramatic end result is either a stoppie or a fall.

This is the reason that has put me off from buying a P220.

The only thing that you could hope for in such situations is to somehow manage to keep the handle straight while panic braking, else one is destined to fall.
I would prefer a stoppie to a fall anyday. I know I am talking as if I am Rossi, but its no cakewalk.

As an alternative one could also use the engine braking and repetitively jam and release brakes to prevent front wheel locking.

I also noticed that the tail wagging reduces on panic braking with a pillion as the heavy front bias is neutralized.

Also, ride a Honda CBR/R15/Fz/Gixxer, to see how the bike behaves under real hard braking. The bike squeals but it still is very much composed with very less tail wagging(w.r.t to dry tarmac, varies on different surfaces).

P.S. : This is purely from my perspective and experience, might vary from person to person. Please feel free to share any other techniques that could be used, as even I am not a 'Rossi/Chris Pfeiffer'.

Re: Slippage of tyre Pulsar 220F


Great help man ! Now I can specifically say the SVC guys to look upon this thing. The biggest problem you know with bajaj is that SVC guys are hardly able to find the problem in 220, and they will just say in 5 minutes that " sir isme to kuch nhi kar skte hum, replace krna pdega ". Really fed up of listening this thing to every SVC I have visited till date in Pune and Bangalore.

Re: Slippage of tyre Pulsar 220F

You should check for the below things

1. Rear wheel bearings
2. Piston condition inside the rear brake caliper

I had this wheel jamming issue, since I own a 220 as well. Upon inspection the culprit was the damaged piston inside the caliper and few rubber O rings were damaged. You can first try the basic troubleshooting and later look for costly solutions.

Getting the bybre caliper will be a costly affair, close to 3K.

When new brake pads are installed the piston inside the caliper has to be pushed inside with a specialized tool. The SVC uses a plier to push the piston inside which damages the surface of the piston and the rubber O ring covering it becomes useless, hence the piston is stuck at one place when the brake is applied.

Re: Slippage of tyre Pulsar 220F



Hi Sanjay
Thanks for the suggestions. You are absolutely right.
But one thing I noticed that like all other bikes have free moving rear wheel, that is not the case with my 220. I always thought that due to rear discs they are like that. At the time my bike was getting washed, with whatever force the washing jet at the service centre applies, the tire wont rotate unless rotated by hand. But this is from 3 years till the time I purchased my bike and serviced several times from that, even the rear wheel spocket has been completely changed and disc plates and pads also has been replaced once.

I just want to know is this a default setup or my bike has this thing only. If this is default its ok, if not then what more I need to get checked.
Changing the disc setup to new bybre one can help ?? If yes, how much they cost approximately ?

Re: Slippage of tyre Pulsar 220F

You need to learn panic braking. Panic braking is also an art. So you need to practice as much as you can.

Indian roads are everyones worry with surprises from here and there. And since 220 is not equipped with ABS all you can do is learn different braking techniques. Lots of videos available on youtube.

And regarding scary moments. I am sure each and everyone of us had a nasty fall once or twice in life, but that doesn't mean you should live in phobia. Regain your confidence and 220 is not such a deadly machine.

If you still fear for wheel lockups, you should move to ABS equipped bikes.

How can you say you have all the skills, the rear brake is not locking up on its own. Definitely it is related to the user who is using it. In this case you. There is always room for.improvement no matter how much experienced you are.

One thing you can check is when the bike is on center stand, try moving the wheel and check if the rear wheel is jammed with the rear brake caliper. If it is jammed then caliper and the piston inside it needs servicing or few small parts replaced. If it is not jammed, improve your braking skills MORE.

Re: Slippage of tyre Pulsar 220F

I would like to say few things about braking on Pulsar 220.

1. I have changed both my tires recently because earlier I was experiencing drastic slippage. I changed front to Birla Tyres 90-90-17 and rear one is MRF Zapper Q (width 130).
2. Tried installing after-market universal abs (Bought from ebay), just like the saferide/krp one, but it was having different grooves so I couldn't fit into my 220. Returned it anyways.
3. Now I'm left with no other option than to improvise my braking skills. Here in bangalore, you will get closed manholes on road a lot (a bit raised on roads here and there) and also many roads with a lot of gravel. So I'm definitely not enjoying my ride and the reason behind I always need to be extra conscious about my tires skidding and then with that much consciousness, you forget the enjoyment while riding way behind. In the stop and go traffic, I do accelerate, but in long vacant roads, I'm even scared to go beyond 50 because If something comes all of a sudden, and I applied brakes even quite properly, then also I'm sure rear discs will get locked up and tire will skid badly and I'll fall down.

Please suggest a way to cope up with this problem because after falling once, Now I have very less confidence while riding and the rear disc even makes my confidence again low, by skidding wherever I suppose it will skid a bit, it does, anyhow I control because of extra low speeds. No other bikes I see skidding so much and this things really disappoints me much.
What should I do ? Is there a real solution ? I also get it serviced regularly so there is absolutely no such problem as my disc plate/pad being dirty. Please suggest me every possible ways in which I can minimize it, not by improving my skills, because I know all those skills and I understand those, but just something I need to get changed or something which can be done to rear brakes.

Re: Slippage of tyre Pulsar 220F

when a dog or a randoms decides to pop up from no where are you gonna do the 70:30 thing or slam on the brakes?? usually when there is time to react i do the front brake first and rear second thing but our roads just likes to surprise us with random things! but for sudden brakes there needs a solution to be found! all ideas are welcome

Re: Slippage of tyre Pulsar 220F




@all who are facing rear tyre skidding under hard braking:
You are doing it wrong! When on Tarmac, start with the front brake. The braking bias should be at least 70:30 favoring front brake.

Only apply rear brake first under non ideal conditions (gravel, off-road, bad roads or any other time you are more likely to skid)

Re: Slippage of tyre Pulsar 220F

is there like any chance to add like a braking assist or ABS to the rear brake of the pulsar 220?? that should improve the stopping distance right?

Re: Slippage of tyre Pulsar 220F

My P220 has done 7500kms. And I too have faced those skidding while hard braking issues sometimes.

I am very careful while using the rear brake. While applying brakes, my approach is to start with the rear brakes. When the rear is almost 20-30% engaged, start applying the front brakes.. keep on applying both brakes until you slow down to the desired speed.. then, release front brake first, and then release rear brake. It has become my habit to brake this way, no matter how small or how long the braking duration is.

This approach prevents rear wheel lockups.

However, at times, during hard braking, I have experienced front tire skids resulting in slight imbalance at the front. I am unable to figure out why it happens. It feels as if the front tire pressure is low and the bike's rims are digging into the tire, creating a sort of imbalance. Maybe its the dust on the road, causing the front tire to slip, yet providing enough traction to keep slowing down. Makes me wonder.. how complicated it would have been to develop ABS software..

Re: Slippage of tyre Pulsar 220F

I had a similar slow speed fall when I was new on 220. Reason of fall was simple touch of a jay walker coming into my way. The person never even felt what touched him.
My post fall analysis pointed to the front heavy construction of bike. And me being new on the bike could not understand how close the front portion was to avoid hitting the walker. By the time I realised it was a close call and handlebars swayed to one direction sharply.
In your case I believe you too miss judged the proximity of on coming innova and realised it at the very last moment. I believe you did not even get a chance to slam the brakes.
A habit of slowing down earlier and lookin for safe passage and proper analysis of the gap beforehand is a life saver.
