At what price are you getting, go for a Rx 135 5 speed you will never regret.

RXG has a problem of too much jerking while you coast with throttle closed, it's a pain in traffic. Later models have got it rectified this when the company started making them with heavier magnet rotor. Still it wasn't really a fun to ride vehicle. The top speed wasn't too great either.

The solution is pretty simple, change the RXG bore with a later model 135's.


RXG was launched to satisfy the pollution norms. I wouldn't recommend this, go for later model 135s or older RX100s.

See if you can get a used RX135 4 speeder for around 8-10k.
Converting it to 5 speeder with all Brand New parts costs around 8-9k.
So by the time you are done with it, you have a RX135 5speed with a brand new complete engine, gearbox and all this for around 16-18k in all.
Not bad for a brand new feeling. Eh?

rascalangel, RXG is not advisable. Go for Rx135 4 speed if budget is limited or else go for 5 speed.

Pretty sure you can convert the 4sp/G/RXZ 4sp to a 5speed .

You will need to buy a 5speed bore - piston kit ~2.8K and then the gaskets and rings and some other stuff with it for another 500 rupees . Total is about 3.3K.

Just replace it with the old one and you have a close-to-5 speed version.

What you will NOT find in any spares store is a original 5speed head and carburetor . Having said that , the 4sp carb on a 5sp setup does ok-ish .

you can also get larger carb jets if i'm not mistaken... so that problem should be tackled.

i don't see why not. just make sure that you find a good mechanic to do all this work. i've seen plenty of mechanics (including company authorised) bungle up big time.

ask around - you might even be able to get a piston kit from thailand which is a bit lighter and enhances the pickup.

Dont install the 5speed barrel with 4 speed head as such.
The 4 speed head has a larger volume. Thus compression will be down. And hence power will be down.
Do you have someone who will accurately cut the head of a 4 speeder and dial in the squish too to get the compression up, then only go ahead.
