Thanks a lot

Re: RX100/ RXG/ RX135: Front Disc Brake Conversion related queries

1) Out of the two, i.e., Gladiator and Pulsar 150 disc sets, which one would be a better choice and why?
A. Pulsar 150 ones are more common and easy to source. My brother's RX135 has it and it does the work really well.

2) How do you compare the two ?
A. Pulsar's setup will be cheaper and easy to source again.

3) Are there any specific modifications required for the conversion, or is it just a 'buy and fit' method?
A. You'll have to check if the forks fit on your existing T. My brother's 135 has the entire handle and front setup from Pulsar (minus the wiring harness and meter).

4) Can anyone please list the spares required for this conversion?
A. Front Forks, Master Cylinder, Brake lever, Calliper, Rotor/Disc Plate, Drive Kit, Meter Cable, Brake Hose and Kit.

5) Is it required to change the T and the crown too?
A. Can't say about the crown but you may need to change the T. Get it checked.

6) I have a 18 x 2.75 wheel as of now. Can I use the same rim with the new Gladiator/Pulsar setup?
A. First gen Pulsar setup with spoke had 18 inch wheels. You can use the hub from the first gen pulsar and in your existing rims. You will need new spokes though.

7) How successful and effective is this conversion? Pros and cons ?
A. Braking is more stable and controlled. So far, I've not seen any downside to this, apart from the fact that the light weight of the bike makes it a bit dangerous to brake hard in emergency situations.

Thanks a lot Bismaya. That clarifies my doubts to a good extent. Will visit the store to get a quotation of cost of spares tomorrow.

Re: RX100/ RXG/ RX135: Front Disc Brake Conversion related queries

Hi all,

Visited a few shops yesterday to check the cost and availability of the spares required for the modification, i.e., the front suspension and and front disc brake setup of a Pulsar 150.

Bajaj showroom gave a rough estimate of around 9k-10k for the entire Disc Brake and Front Absorbers setup, but then surrendered that they won't be able to source the parts as these parts are out of supply.

A spares retailer gave an estimate of about 5k-6k. Unfortunately the spoke-hub was not available with any of the retailers or even the showroom.

As of now, a local mechanic who modifies 2-stroke bikes has promised to get me the entire setup (used) for 4k. Will get the next update on Saturday.

Buying a decent one in a used condition is your best bet. That's what mine has. Also, buy the forks of Pulsar 150 Classic (Round Headlamp) or else they won't fit the RX Tee.

Re: RX100/ RXG/ RX135: Front Disc Brake Conversion related queries

Hi guys,

Luckily my mechanic managed to get hold of a Pulsar 150 disc brake and front suspension pair (not in the pic)......here it is :

Re: RX100/ RXG/ RX135: Front Disc Brake Conversion related queries

Nice find! Best of luck I'm also planning on investing a front disc setup for my bike.

Re: RX100/ RXG/ RX135: Front Disc Brake Conversion related queries

Hi guys,
Finally, its done.

Front disc brakes installed in my RXG.

Disc plate is of a Pulsar 150 old model, but the suspension system is from it's successor, the DTSI model, hence I had to broaden the T and the T-plate/crown holes slightly in the lathe. The brake and clutch levers and yokes were replaced with the pulsar ones along with the bar ends.
The brakes are working pretty well now. Here are the pics of the process:

Re: RX100/ RXG/ RX135: Front Disc Brake Conversion related queries

Hey Guys, I am getting an old pulsar front-disc-brake setup for my rx100. Now, I am worried whether it will have a provision to use the brake switch from rx series. Could anyone please confirm the same? If it does not, then what do I need to do to install one? Appreciate your time & help.

Re: RX100/ RXG/ RX135: Front Disc Brake Conversion related queries

You should use the switch from Pulsar and change the 2 pole socket to 2 independent bullet connectors (from RX switch)
For neat & secure installation, get new bullet connectors and crimp them with insulators.
Other option involves wire cutting, use the wire and connectors from existing RX brake switch.

Re: RX100/ RXG/ RX135: Front Disc Brake Conversion related queries


Thank you so much, Mr. Boss! I will try as you suggested once I receive the parts.

Re: RX100/ RXG/ RX135: Front Disc Brake Conversion related queries

I have the old stock pulsar Front disk installed with stock Disk brake oil setup . No issues at all since 6 years .
