lolx i m not the king maker rather rider;)
i think if u would ask about parts then we all king riders have dump of parts at home, coz jesay hi parts junkyards main available hotay hain we do jump for them, or ager kisi bhai ko zrorat par bhi jay to we all are here to share,
115 and rxk135 main thora hi difference hay
power
115 is 15.5ps
135rxk is 18.5ps
rxz135 is 20ps
jahan tak 115 ko 135 kernay ki bat hay to woh buht hi aasan hay just swap the cylinder block, replace the clutch box, carb and thats it
