^ RXG came with Mikuni VM22? I thought RX100 came with VM22 and RX135 4s uses VM20 and not sure RX135 5 speed uses. Clarify, this would be of great help.

rx100 came with vm20 (20mm venturi dia)
rx135/rxg came with vm22 (22mm venturi dia)

hope this solves the confusion

As my search for Stroker has started,
would wish to know the basic differences between RX-100 and Rx-135.
I know the 'cc' difference, but interested in knowing that why RX-100 is most preferred stroker.
What was wrong with RX-G? It just doesn't sell well even as used.

@ sheelpriye: The basic difference is that the RX 100 made 11bhp and the RX 135 4-speed made 11.8. The RXG made about 10 bhp because it was mostly a stop gap measure by Yamaha to comply with the emission norms, so power took a hit.

The same thing happened with Ferrari in the early 80's, when they introduced fuel injection, there cars lost 30% power. Yamaha did better by comparison.

The real reason blokes prefer the 100 is because it comes with a standard fitment which is not even optional on the 135 - a POWERBAND.

The 135 accelerates smoothly whereas the 100 is like nothing...nothing...nothing, and then WHAM! all the power comes out in one go. Which makes it very exciting, to say the least. Also, the reliability of the 100 is way ahead, because back then the quality of Yamaha was beyond compromise.

I am looking for a decent 135 4-speed in Kolkata, for a crazy project, will let everyone know when I start.

There were lot of differences, like the CC, BHP, Clutch unit, sproketing, Electricals, Crank shaft....

There is nothing wrong with RXG, but its just dint create the wave that RX100 did.

And about RX100 being the most preferred stroker, the reason is, it is the one which started it all (THE ADDICTION). I have nothing against any bikes here, but the entire RX series were legends, be it 100/G/Z/135.

ANd FYI, an RXG can be easily converted to 135-4-speed or 5-speed.

Powerband exists in all IC engines. It can be more so felt in 2-T & less in 4-T engines.

I am not so sure about the acceleration you have mentioned & also the quality. Even to date RX135 is considered the best 2-Stroke (Under 150CC) ever in India. 100 was good, but 135 is better. These are strictly my views & i am sure many will agree to this.

In simple words, "There is no bike in India as mod friendly as the RX135". Its about time you tasted the madness of modified RX135.

P.S: Let us not start some fight here as to which is better etc etc, but more so focus on saving these beauties. The question more so seemed as which is better " LION or TIGER" !!!!

This is what I'm trying to explain here. The 135 made power throughout the rev range in sufficient quantity, so the acceleration is much smoother as compared to the 100.

It would be like that only, considering they made nearly identical power, but the 100 did it with much less capacity.

Therefore, the power of the 100 was concentrated in the top portion of the rev range, and the kick of the powerband is absolutely noticable, even if you're half asleep.

Some people, like me, prefer the smoother delivery of the 135. Others, like two of my friends, they prefer the kick-in-the-guts feel of the 100.

At the end of the day, it all comes down to personal preference. Bottom line: whoever is reading this thread loves strokers, and it doesn't matter what they prefer.

As for experiencing the power of a modded RX, well, a friend of mine in Ahmedabad has this 135 with Proton expansion, porting, polishing, VM24 - the works basically. It also has a unique frozen blue paint, but that's another story.

I do not encourage street racing in any form, but I should add that when some guys met up at a closed down and deserted road in Gandhinagar at 2 in the morning, the 135 gatecrashed the 4 stroke party and went home with top honors, leaving "Kn'N"-ed CBZ-x, Karizma, 200, 220 to bite the dust.

Warning: the above incident happened in a closed and controlled environment with full safety gear, please do not try anything on public roads.

Just love that sight. I only wished the RX-Z 6-Speed was in India & we could see this happening more often, rather always !!!

Thanks for the inputs
I think i will go for the 100 again.
Which part of Calcutta do you reside in?
There are good 2st mechanics in Behala i heard.

With terms to engine reliability, i feel that both the RX100 and 135 are equally reliable.

A point of debate i would like to point out was that the 135 was a designed and developed bike. The 100 was a undersized version of the 135 in india, because it has not been sold anywhere ( The other 2 stroke commuter 100cc that Yamaha had, was a twin cylinder, like the RD ).

So if the engine was peaky, because it was a derivative of a bigger sized bike. The 135 was the actual bike, and hence had a smoother power delivery.

For what it was and what it is ( super reliable, durable, and long lasting ), yes the RX makes a lot of sense, even now, as a no nonsense bike.

But let apples be apples, and oranges be oranges.

Also the RXZ6speed does make 21PS, but again due to a peaky powerband, its very difficult to put all that power on the road, not making for a very drivable bike, hence the 6 speed gearbox to use the power comfortably.

I have ridden Yamaha RX135 4 speed for many years........simply exchanged my school buddies bike with my Shogun most of the days.

Suzuki Shogun moved like a RX100 on nitro kit infact.......so much kick in the higher rpms that the bike wheelied most of the time....though it felt like a Samurai at low rpms.

Yamaha RX135,is exactly opposite,you find power anywhere,I used to sit on the bike,stick the throttle slowly.....it moved,then a bit more,wind in my hair bike is speeding past 80kmph on its analogue....and that rush of feel from the 135 and that nostalgic engine note HONNNNNNNNHHHHHHHHHHhhhhhhhh...

Shogun was much more peaky than the RX135,it loved to be revved hard and bring the Hundred up in a chaotic way,smoking away to ecstasy.
The RX135,relaxed and then went for the speed,80-90-100...like this,but the bike felt less stressed.

However RX135 is not in my luck......I have projected my thoughts towards Shogun to tune it a bit more.....I am doing all like the TVS did on the 24hp Shogun,except the GroupC ignition coil,without that my bike wont make more than 17PS......would have to be satisfied with that only

Would love to ride it someday, considering the fact that I use all the revs available in all gears to keep my Motorcycle movin'

My place is up north, Lake Town, but I have places to stay almost all over the city . You from Cal? Then help me out with the search

Their was this Yamaha called the RS 100, which was different in engine (15 bhp) and gearbox (5 speed), but every other component was identical to the RX 100. There is one for sale currently on eBay Motors, USA, here's a screenshot of the page:



If you want to see the listing, just type the item number into any eBay site search box.

For this reason I asked Yamdoot Ji about converting an RX 100 engine to a 5 speed setup, to better utilise the torque. He advised me against it, and told me to go for the 135 4-speed instead, as converting that to a 5 speed spec is easy.

This is why I am looking for one. I am inspired by nitro-1000bhp in creating a vintage trail bike.

Happy (2T) smoking!

1eighty.....try to get the technology and engine and carb specs on the RS100 so that it can be emulated on the RX100 engine to pump out 15PS....i honestly think RS100 is a big port job like the Shogun itself.

Though RX135 will always have the CC advantage.

Nopes.

I stay ~500kms away from the City of Joy. Purnea-Bihar
