Go ahead with the RTR 160's chain-set..My brother is running his A150 with 160's sprocket and chain..Experience has been fruitful so far,and he's enjoying his ride..Says,it's a totally different bike now..

Will enquire more on this from him,as I have no idea of the mods undergone...Wait till 2mrw morning!(if you can)..

thank you buddy for the info. Will surely try to get the RTR 160 set. And i can surely wait till friday or saturday because thats when i will get these things changed

I am running a P220FI chain sprocket kit which has an O ring chain on my P180UG3. The sprockets were a direct fit. The chain was longer than needed. So the mechanic just removed 3 links and everything was installed as clean as stock. There is no need to CUT the additional links. The pins holding the consecutive links together can be hammered out and the links can be removed. The same pin can then be hammered back in..

Don't be confused/scared of hammering the pins. Pins are supposed to be installed/removed by means of hammering itself. Just that too heavy hammering may damage the links.
