Do you guys think this would be a good deal?

Yes i do, This can make a perfect offroader and a city freak, that too @ 10K sound really nice !

Hi Shoaib,

Its a great fun bike to ride and sounds good too. I remember riding this when it was launched back in the 90's. Even though 10K sounds very tempting, before you pick it up, please check for availability of major spares ( Cylinder, pistons, clutch bell crank etc) as KB spares are not too common IMO if you ever need them in the future.

Worth it. Trust me these things are a blast to ride. Shocks and clutch plates can be changed on this bike no problems. It is more reliable that people think. So go for it and don't look back.

Its an Awsome Bike.Is the bike in running condition? Quote for 7-8 K max. Before that check for the availability of the fibre body parts. Its too rare to find. As its having KB100 Engine, Hunting Engine spare parts wont be a head ache. One more doubt, If the engine is completely overhauled, how the clutch plates wont get noticed in this overhaul?

Its a good fun machine . If all the parts are intact, u can offer about 8k.

It is the only 2 stroke bike in India which has ever come with a factory expansion chamber so make sure the chamber is there in good condition.

KB parts are a bit difficult to find so if you buy this one, start collecting parts from day 1.

Bajaj SX-100 (Enduro) - Is it worth it??

My personal opinion (please don't shoot me for it :-) ). You would be better off looking for a good RX100 or Shogun. This bike was what we use to call, 'all show, no go'. It started out initially as Rahul Bajaj's tinkering around project when he had just joined Bajaj Auto. Poor quality plastics which were flimsy and rubbish suspension were the hallmarks of this bike. An enduro style bike with poor off road capabilities, it was a bike that never sold in any great numbers and disappeared very quickly from Bajaj's offerings.

Someone mentioned that it had a expansion chamber. Again for show and not for performance (a well designed expansion chamber can provide as much as 50 - 100% improvement in power out put). It made no more power that the stock KB100. It was for posers and not for performance oriented.

The fiber body parts look to be in order..one corner of the front mudguard is a bit chipped. Will see what can be done with that. The bike has been sitting idle for almost 6 months and that's the reason of the bad plates.

That's the first think I looked at and confirmed about the bike. The chamber is original and in decent condition.As for the parts, I've started looking already and back to hunting shops at Nanapeth this week. Will nose around in Ahmednagar and Aurangabad too when I go there over the weekend.


I'm very much aware of the bike's awesome reputation!! . Going for a 100 was my initial idea too.But then again..too much money involved and a big restoration ahead. I would be better off buying a used Hero Impulse in that case.


Yup..you are right..I really don't like the front headlight thingy and gonna replace first when I get the bike.

I really want to get the bike for its freak value(Posing ), available dirt cheap and which I can trash around. As for the suspension..will definitely be changing it to a mono-shock with a longer swing-arm.

Thank you all for your valuable inputs. I almost made up my mind and will finalize the deal this weekend.Definitely, will haggle to bring the price down as much as possible.

I was also researching up a bit and had a couple of questions-

1.The bike is definitely running on some size of Oversize pistons and I would really want to change the block. Can someone please tell me if the engine is completely stock KB100 or the porting is different?? I read somewhere that the power delivery is in the low revs for this bike.

2. Can we fit a KB125 block on the bike?? Are the engine mounds same?

3. I will be changing the instrument assembly as I really dont like the KB one. Any ideas which one to go for.

If you made up your mind to buy, then go for it dude. If cops catch you for riding dirt bike in city, Atleast You can argue with the cops that its a stock bike.

Regarding the differnce between KB100 & 125,Please find the points written by psr on post #125 on below link..




Also please find the service manual for KB100 at below link which was already posted by one of our BHpian.POsting it again.Thought it might help you.

Thanks Vimalnair4u.

Yup the cops can see the papers and shut up!

Damn...thats guy knows his stuff!! In short...I get that I would have to use the KB100 bore.

That's a great manual..Saved it before sending the post.

On a lighter note...I'm a bit on the heavier side..so I was wondering how I would look on the skimpy Enduro. Saw a video that had me rolling...and a lot more weight conscious!! Have a look at the video... I 60% look like the fat guy on the Red Enduro ( Alright 70%!! )...again

If you can put a video where you are riding Enduro, I can be able to give a better number(60 or 70%)

Well..now that my YEZDI (HADES) is all done up..Its time to start work on the Enduro. Finalized the deal last weekend for 7K
as per inputs from Yamdoot and Vimalnair4u.

The sad part is, she is currently running on her last oversize.However,did manage to source a used RTZ block running on 2nd oversize and that will be going on the bike temporarily till I can source a new standard one. Will now be hunting shops again and search for the new parts.

I've got butterflies in my stomach thinking about a new rebuild.

What I've thought the Enduro should look like -
Everything stock except for
a) RD350 speedometer and tachometers
b) A KB / Bajaj 4S Champion rectangular headlight
c) Rear mono-shock with a really long rear swing-arm.

Parts to be sourced -
1. RD350 speedometer and tachometers
2. A KB / Bajaj 4S Champion rectangular headlight
3. Cosworth air-filter.
4. A race throttle.
5. Motul 300V oil.
6. Running items like cables, brake-liners, clutch plates.
7. A KB100 RTZ block and pistons.
8. Front and rear drums, if I can get my hands on them.

Paint job -
This is the first time I get a chance to get real wacky with the paint job. Have thought about the Kawasaki Ninja green or the Yamaha yellow but not finalized it yet.

Moreover, I haven't done the bike's Naam-Karan ceremony (naming the bike). So, if you guys have any ideas, just shoot.

Cheers,
Sohaibak

for the front and rear drums , go for the 130mm ones from caliber 115/discover 125/pulsar/wind . its a direct fit

Thanks for the info KB100. Really love the link in your signature. Makes my rebuild a whole lot easier.

Cheers,
