    Differences & Similarities between 135cc RX series

    Have seen quite a few people owning RX135s in GH & hence i am sharing this info which i had posted in xbhp.com.

    Source: http://www.xbhp.com/talkies/thumpers...rx-series.html


    ----------------------------------------------------------------------------------------------------------------------------------

    I am listing down some basic differences & similarities between 4-speed & 5-speed versions of RX135 (Includes RXG & RX-Z), which will help people to differentiate & learn more about these legendary series once produced in India.


    1. Bore Kit (a.k.a Piston-Cylinder Kit / Barrel / Block)

    4-Speed - '4TL00' with OEM "ART" STD piston '4Y201', Rating: 12BHP @ 6500RPM
    5-Speed - '4TL10' with OEM "ART" STD piston '4Y201', Rating: 14BHP @ 7500RPM


    Note1: To check the originality, the LH side of Cylinder (Gear shifter side) has ‘4TL00’ or ‘4TL10’ marking along with ‘132cm3’ (which is the displacement) and the RH side (Crank Kicker Side) has the batch of manufacturing, for ex., E1, E2, E3 or E4 (All of them have exactly similar performance, people who swear by performance of E1 being the best, is all crap.) Also if nothing is mentioned or some other type code is mentioned, then the Cylinder is a fake, except for '4Y201' which is the original block of RX-K.

    Note2: The Cylinder packing has the following description on it:


    1. RX135 4-Speed / RXG / RX-Z 4-Speed: "Cylinder Kit RXG"
    2. RX135 5-Speed / RX-Z 5-Speed: "Cylinder Kit 5-Speed"

    Note3: Displacement calculation

    For Std RX135 being a single cylinder engine, we have the following inputs,

    Bore Dia = 58mm
    Bore Radius = 58/2 = 29mm
    Bore Radius Squared = 841mm2
    Stroke Length = 50mm
    Pi = 22/7 = 3.142857
    Number of Cylinders = 1

    Displacement in mm3 = Stroke x Bore Radius Squared x Pi x No. of Cylinder
    = 50 x 841 x 3.142857 x 1
    = 132157.143

    Displacement in cm3 = 132157.143/1000
    = 132.157 (Corrected upto 3 decimals)



    2. Piston Kit

    The OEM Piston kit for Indian RX135 series are from "ART" Japan. For Indian models piston sizes from STD to 0.5mm are available (in steps of 0.25mm). On careful observation of the piston, one can identify if it is original or not. Simply turn the piston upside down & inside we can see "ART" & "4Y201" clearly written. This is the proof for original piston. The piston kit essentially comprises of

    · Piston (STD/0.25mm/0.5mm)
    · Piston Rings
    · Piston Pin
    · Clips

    Note: The pistons are the same for RX135 4-Speed, RX135 5-Speed, RXG & RX-Z.




    3. Carburettor Assembly

    The OEM Carb assembly for RX135 is Mikuni / UCAL Mikuni. The Carb assembly are different for both 4-Speed & 5-Speed versions.

    4-Speed: '4TL 01' with Main Jet = 165 & Pilot Jet = 17.5
    5-Speed: '4TL4 20' with Main Jet = 135 & Pilot Jet = 15.0

    These are VM type of Carburettors manufactured by Mikuni & both are 22mm. Additonally VM24 & VM26 are used for RX available in South-East Asian countries (Like Singapore, Indonesia & Malaysia) and in South American Countries (Like Peru, Argentina & Brazil). The details of these are given below:

    VM24: '2YA 00' with Main Jet = 145 & Pilot Jet = 20.0
    VM26: '55K 00D' with Main Jet = 210 & Pilot Jet = 22.5

    These carbs (VM24 & VM26) are direct fit to Indian RX135s with some minor jetting changes required based on the Power output of the engine.

    Note: The type code is mentioned just above the 2-T oil Inlet in the carb, with that the originality can be confirmed.



    4. Head Assembly

    The heads are also different for 4-speed & 5-speed. The type code is mentioned below:

    RX135 4-Speed: '4TL5' written on inner side (Top) of Head (For OE fitting Catalytic Converter type)
    RX135 4-Speed / RXG: '4TL00' written on inner side (Top) of Head (For OE fitting Chrome Silencer)
    RX135 5-Speed: '09L' written on inner side of Head



    5. Clutch Bell Assembly with Primary drive

    The clutch bell assembly are the same for 4-speed & 5-speed RX135 (Including the number of Clutch plates), but it is different for RX-G. Below are the differences mentioned:

    RX135/RX-Z 4-Speed/5-Speed: Main Bell = 74 Teeth
    Primary Drive = 19 Teeth

    RX-G : Main Bell = 71 Teeth
    Primary Drive = 22 Teeth



    6. Chain Sproket

    The sproket (Front & Rear) are all different for entire RX series. Detailed info given below:

    4-Speed: 16T / 34T
    5-Speed: 15T / 38T
    RX-G : 15T / 37T



    7. Gear Box
    The Gearbox are obviously different for 4-speed & 5-speed. Details below:

    4-Speed:
    1st = 35/11 = 3.182
    2nd = 30/15 = 2.000
    3rd = 26/19 = 1.368
    4th = 23/23 = 1.000


    5-Speed:
    1st = 35/11 = 3.182
    2nd = 30/15 = 2.000
    3rd = 26/19 = 1.368
    4th= 24/22 = 1.091
    5th = 22/24 = 0.917



    8. Engine

    The engine may be classifed based on Top End (Included Cylinder+Piston & Head) and Bottom End (Includes Clutch Assembly, CrankShaft, Engine Bearings, Crank Kicker, Engine Cases, Clutch/GB Covers, Ignition coil, GearBox Assembly etc as major components). Most of these items are already covered in points 1 to 7 above.

    Note1: The RX135 4-Speed & RX-Z 4-Speed share the same Engine, likewise RX135 5-Speed & RX-Z 5-Speed share the same Engine.

    Note2: The CrankShaft Assembly is the same for RX135, RX-G, RX135 5-Speed & RX-Z.

    Note3: We can identify looking at the Engine number if the Bike was a 4-Speed version or a 5-Speed verion. Check the details below:

    1. RX135 (With Chrome Silencer as OE fitting): 1L5 XXXXXX
    2. RX135 (With Catalytic Silencer as OE fitting): 4TL XXXXXX
    3. RX135 5-Speed: 1L7 XXXXXX
    4. RX-Z 4-Speed: 1L3 XXXXXX
    5. RX100: 1L1 XXXXXX

    P.S: The RX135 5-Speed never came with OE fitted Chrome silencer, the OE fit was the Big Hot-Tube type catalytic converter Exhaust.


    Any comments/additions are most welcome.
    Thank you.

    Pollution. Thats why they came up with a cleaner & refined RXG a 132cc 2-stroker based on RX-King. This is the exact same reason all the 2-strokes performance bikes were stopped way back in 2004 itself (RX135 4-Speed with 5-speed clutch/GB covers & round meters was the last of it).

    There was an elusive RX125 also in cards, but it never really took shape.

    Ah, those good 'ol 2T smoking era, how i wish RX is relaunched someday.

    RX100 is a legend, but the 135 was just better.

    As said by karthikdattag, because of pollution it was banned by the government not to use in indian roads.

    Owning an RX100 was like great. It will pull you like anything when you rise the throttle. After 100Kmph you can very well feel the difference.
    Never Say Never Again :)

    IIRC RX 100 was stopped in 1994 or may be 95, however there were other 2 strokes in the market. I am still not able to understand why they stopped this!! Shogun was re-launched with catalytic converter when there was a pollution norm but why Yamaha din't take this route??

    RX135 will never be a replacement for RX 100, I am sure you would agree to this

    I still feel Shogun was better than RX

    Hi Karthik,
    I have heard some strange story about Rx100 that goes like this.
    The RX100 was actually a 135cc bike that was launched with the Rx100 name. No other 100 cc bike at that time could match its power & performance for a long time.
    Then Hero Honda came along and found that RX100 was actually a 135 cc bike. They complained and Escorts Yamaha had to stop this model and then launch it again as RX135. The story further claims that if you compare a Rx100 and Rx135 engine (4 gear), both look identical in size and shape.

    Please comment.

    Nice story k a s h

    IIRC, RX100 was put to rest after the emission norms became stringent..

    There are lots of urban legends around these Yamahas... Here is another...The first six RD350's that came out of the Cochin dealership (we had only one dealer in Cochin at those times) met with fatal accidents and the seventh one onward they were custom tuned for reduced power to save lives...

    The controversy I remember is Yamaha was caught in some race / rally inspection or something like that. Must have been the TVS boys who would have noticed. If you remember, there was a brief period where the RX100s actually had 100 emblazoned across the fuel tanks.

    There was a 125 which was not officially released. Car & Bike International (if you remember the magazine) had a review.

    I doubt Hero Honda had anything to do with it - they would have been busy adding mudguards and engine guards to the CD100 and coming up with CD100 Deluxe, CD100SS etc.

    Euro1 was introduced in the year 2000 - and with that the 2-stroke era came to an end. NO two stroke motor can conform to even this basic of emission norms.

    Secondly the huge bulk of the motorcycle market was interested in only three things.. mileage, mileage and mileage. No way a 2-stroke could compete there either. (remember the 'fill it, shut it, forget it' campaign that made Hero Honda what it is today?)
