relax dude its cool

wasnt there a nsr 150 engined pulsar sometime back

^^ Yupp you are rite, its one of rajkumar11's collection ..

There are so many RX variants.............!!!!!!!!!!!!
Actually its now me who is feeling out of punch
But I know there was a 110cc RX100 in the 1985-1989 saga for sure as its very well known in 2T circles.

However leaving aside this whole issue of which is better 2t or 4t lets focus on 2ts here since this thread is dedicated to Indian 2T bikes.
Now I want to turn the attention towards Suzuki's gifts for 2t in India.
Four of them...........
1.Supra SS powerup (16bhp-launched in 92',discontinued in 93', 98cc engine)
2.Shogun (14bhp-undiluted power,a featherweight legend)
3.Shaolin (11bhp-First 5 geared bike of Indian make,famous among tuners,Joel's favorite)
4.Shadow (16bhp- also known as Shaolin Hp,Joel knows it all,though officially it was never sold)

apart from these Samurai,Supra and Supra S,AX100,MAX100 all are 2t commuters,basically Splendour took their market

My focus is on the first four, truly speaking Bike 1. and Bike 4.,
Mysterious as they are with very short launches and no product lifetime, but they are actually the marvels of Indian 2T after RD350 and along with RXZ 5-speed.
for Bike 1............16bhp from 98cc, anyone,anywhere please shed some light as to what was different with this bike's engine,how did it make so much power from that 100cc ????
for Bike 2............ 16bhp from a 140cc engine,sounds good,Joel please explain the tech behind,was it a Shaolin displacement and crank case with a Shogun porting and expansion chamber ????

Jd666 and others if you have any info on these mysterious ones please enlighten

Well, if you look at it one way, these bikes were sold (In India, pak and Arg) at a time when the RD was sold in India so you don't need to feel so bad

Bajaj Auto set to launch 2-stroke engine bikes

Bajaj Auto set to launch 2-stroke engine bikes - Trade Headlines, Current Business News, News and Current Events, Sme News Archive

Dont know if this is true, but surely give some hope that some day we will see 2-Strokes in action again with a better technology. Meanwhile just enjoy reading the stuff & any info / comments are most welcome.

BIKE and scooter major Bajaj Auto is all set to bring the two stroke engine bikes back to the Indian market. The legendary two strokes engine technology, which was launched in the early 1990s (Bajaj Chetak, Kawasaki Bajaj 100, ) have already been launched in three-wheelers as Gasoline Direct Injection (GDi), which is superior with increased mileage and substantially less emission. The company is likely to customise the GDi technology for its two-wheeler products in the next few months.

Bajaj Auto has introduced direct injection technology (as the GDi name suggest) replacing the carburettor which delivers better fuel efficiency and higher power (torque) than the conventional two-stroke engines. It also meets the stringent emission norms with 50% lower carbon monoxide ((CO) and 25% lower hydrocarbons and nitrous oxides (HC+NOx) than the earlier two stroke engines, which were phased out by two wheeler companies because they failed to meet the required emission norms. A senior Bajaj Auto executive confirmed that the same engine is likely to be strapped on a two wheeler. “It is a big leap in the two stroke technology and we are working to get it on our bikes and other two wheelers. The Gasoline Direct injection (GDi) engine has substantially lower emissions than even alternate clean fuels like CNG and LPG. Additionally, it has lower operating costs than four stroke technology that currently dominates the bike market.” According to sources in the automobile industry, Bajaj is working to combine its proven DTSi technology with the GDi technology on bikes with smaller engines. The company wants to put the same technology in the volume generating 125 cc-150 cc segments as an alternative to the existing four stroke engines. Bajaj Auto is also in the process of developing two wheelers that will run on CNG fuel.

The two stroke engine had been a success in the past due to its higher torque (power), faster pickup and better vehicle stability due to the smaller engine. Company officials said that in the GDi technology, the fuel is injected through a common rail fuel line directly into the engine’s combustion chamber where it is completely burnt unlike the conventional carburettor run two-stroke engine which leaves out unburnt fuel and results n higher emission. After successfully launching the GDi-run three wheeler, the company is working on different variations of the technology which can fit into smaller vehicles like bikes and scooters. Some prototypes of the new technology is expected to be unveiled at the upcoming Auto Expo in January.

Why is Bajaj still called a scooter major, or is this old news?

Thats a Fuel Injection on a two stroke.............a fashionable name GDI(gasoline-fuel,Direct Injection)

Bajaj's technological result is...............higher power(torque),which means very torquey engines with not much Top speeds,low on Bhp.These bikes are going to be like diesel vehicles,high torque and low bhp.The engines sizes would start atleast from 125cc, to earn a respectable power figure.

I however think, even this is going to take time as they are declaring its prototypes for next Autoexpo,by then market would have numerous very fast 4 strokes available and affordable too.

These new 2t vehicles would be pulp fiction in comparison to old school 2ts.........the real 2Ts

This is nothing but Direct Injection, different names thats all. Something similar to our CRDI (Common Rail Direct Injection) in Diesel Engines, names figure out differently by different manufacturers, like, CRDe, CRDI, DI, TDCI, DICOR etc etc.

But nice technology though. Would love to see Yamaha launch these with such a technology. But again its just a hope, this is what we all do, Hope for the best.

Two Strokes fight Four (RX100 Vs. FZ-16)

Here's the article from Hindustan Times (Sourced from AutoCar India). ENjoy..



P.S: Please dont go for the number game here, it mentions that RX100 did 0-60Kmph in 7secs, but quite frankly its a 20Yr old machine we are talking here, just imagine what it could have done 20Yrs back !!!!

Abundant foliage, few people, fewer buildings, and traffic-free roads decorated with trails of blue smoke, courtesy Japanese two-stroke bikes. Isn’t this how all of us remember urban Indian streets of the 1980s?
Biking was fun, fast and simple as the machines delivered maximum thrills per rupee, and lasted as long as a decade. Some of these lightweight screamers remain etched in the hearts of bikers, especially Yamaha’s popular RX100. So it was only fitting that we brought together two iconic motorcycles — the RX100 from the past and the FZ-16 from the present.

Old is gold, new is bold

The RX100, a handsome model in its day, sports simple lines with attention to detail seen in the parallel piping on its slender fuel tank. This minimalist, bare bones style is today only comparable to a basic commuter bike. Three body instruments include a cable-fed analogue speedometer, indicators for the turn signals and a neutral light. And while shiny bits may be frowned upon by today’s buyers, bling chrome used to be impressive once upon a time, just like what shines out from the RX’s front and rear mudguards, handlebar and silencer.

Sit astride the FZ-16 and you can see how motorcycle design has evolved over the two decades. A burly motorcycle, the FZ looks like it only just exited the gym when parked next to the lean-looking RX100. The FZ is loaded with eye-catching details. Its smart alloy wheels, angular headlight, sculpted tank and stubby silencer are all sure to leave people lusting after it for years to come. The FZ-16’s sci-fi all-digital instruments aptly show how equipment levels play such an important role in bike-buying decisions today.


Heart of the matter
The RX100 belongs to the time when global warming was the least of an Indian biker’s concerns, and 2T lube stains on jeans were quite acceptable. Powered by a two-stroke, 98 cc, single-cylinder and air-cooled motor, the RX100 was good for 11 bhp at 7500 rpm. And that’s talking a stock bike. But in the hands of an experienced tuner, the RX became capable of violent acceleration. Enhanced, hand-polished transfer ports, a higher compression ratio, bigger pistons, lightened engine internals, modified carbs, tuned exhaust systems, sprocket kits and tweaked gearboxes were all modifications that could be implemented on this sturdy motorcycle.

Let’s ride the bike. Spoilt by creature comforts such as electric starters and handlebar-mounted choke levers, it takes time and a forgotten knack to kick-start the RX. However, once brought to life, this beautiful bike settles into an audible, if perhaps tame, idle. A twist of the wrist, and its high pitched and loud two-stroke exhaust note takes over. As we get moving, I’m tempted to whack the throttle open. My right wrist obliges, and the bike takes off.

A decent low end is immediately followed by a potent burst of power as the revs build, with the bike buzzing like a horde of angry bees. As I nudge the beautifully weighted clutch and work upwards though its smooth-shifting four-speed gearbox, both speed and fun factor increase. I’m already starting to understand what the big fuss over these lunatic two-stroke bikes was all about.

Tightening emission norms were to finally sound the death knell for these power-packed two-stroke engines in India. While four-stroke units are cleaner and greener, they seldom provide the undiluted rush of adrenaline common on their highly strung predecessors.

The FZ-16 with its silky smooth, four-stroke, 153 cc, single-cylinder and air-cooled engine is not half as involving to ride as the RX. Maybe the mechanical equivalent of a dose of steroids injected into its wide powerband would make matters more entertaining.

The test begins
We come across a long, empty stretch of tarmac that’s promptly turned into a makeshift drag-strip. The numbers favour me on the FZ, this bike taking 5.59 seconds in the sprint to 60 kph compared to the older Yamaha that achieved the same in close to 7 seconds.

A larger engine, newer bike and more power are ingredients that generally win you speed runs, so my money’s on the FZ. Despite a slower start, the plucky RX with a healthy power-to-weight ratio proves it’s still capable of keeping right up with the FZ in the right pair of hands.

As we raced on, the odds stacked up in favour of the RX100 on the straight and open roads. Then came some corners, and with these, major chinks in the RX’s lightweight armour started to show through. It is Usain Bolt in a straight line, but the bike fails to match the FZ on a twisty road.
Large 18-inch tyres make the RX feel a little more reluctant, while its upright riding position starts playing spoilsport as well. Also, the RX’s skinny double cradle frame, telescopic front forks and twin shock rear suspension work as selfish components, with handling not really coming together as nicely as on the FZ, where the sum of all parts adds up to make for one well-mannered motorcycle.

Pushing the RX around a corner calls for a lot more planning, cautious speeds and the problem of braking. Drums of 130 mm, both front and rear, were ample when the RX was enjoying its days of glory, but in an age where front discs are making it to budget commuter bikes, drum brakes are inadequate.

Switching over to the FZ after the RX makes me immediately feel at home. The FZ features the latest and best bits on Indian motorcycles, delivering an excellent combination of straightline stability and cornering flexibility. Handling prowess has clearly been a priority from the design stages of this bike. The focus on centralising mass has paid rich dividends in the way the FZ gets around corners. Everything from its single downtube frame to beefy front forks, seven-step adjustable monoshock rear suspension and low-profile tubeless tyres work in unison to deliver a superlative experience.

Verdict
At the end of a day of hard riding, I understand what makes the diminutive RX100 so legendary. It may not have alloy wheels, disc brakes, a mono shock or an electric starter but what it lacks in frills, it makes up for with a rich character.

The FZ-16 comes with the bells and whistles of modern bikes. It’s an outstanding package and generations ahead of the RX100. It makes me feel we haven’t noticed all that our bike manufacturers have achieved over the years. Always hungry for newer technology, we’ve overlooked the small changes they’ve made while improving models over the years. For instance, how better frame designs and the shift from tubular swingarms to sturdy rectangle section units have made such a difference to the way motorcycles handle. How disc brakes and improved suspension make our rides more comfortable. Alloy rims make tightening and adjusting spokes a thing of the past. And it’s clear that enhanced reliability with high-quality parts no longer call for frequent trips to the local mechanic.
Put a gun to my head and I will pick the FZ. But ideally I’d like to keep both Yamahas. The comfort and reliability of the FZ are just what the doctor ordered for my daily commute, while the RX100 is for that weekly kick of motorcycling excitement.

^^^ good read !

thanks bro !

Yeah its the same article that JD666 and Myself were talking about, though the numbers here are rounded up instead of precision, however doesn't make a huge difference.Nice informative piece this is

But please, somebody help me about my queries...........the mysteries of the two bikes as in page5,post number 49,which is my post.

@MACH50; im not an expert historian of these bikes but here is what i know its from an article in overdrive mag when tvs released its 125 and 250cc mx bikes the 16 bhp supra you are referring to here might be the supra ss which was used for rallying....also a fuel injected shogun or shaolin engine was shown in an auto expo in the 90s althouh nothing came of it(source bike india)

Thanks from my side to you
Atleast you came up with something,whatever you know off.........all others seem to be silent,as if there was nothing like this...........Joel knows it all......and even he has fallen silent ....

@KB100.........so what mods did ya carry out on your bike ????

@MACH50;if u are referring to our kb100, none will be the answer...she is a 20 year old disc valver and is undergoing a rebuild right now http://www.xbhp.com/talkies/thumpers...rebuild-4.html
