Yes, you can, the batteries are of similar AH and voltage. Just make sure that the plus and minus terminals of the new battery are correctly placed for the battery leads. Disconnect the negative terminal first when replacing the battery.
there is no oil filter in Honda rebel 125. i believe the sump plug is magnetised and this draws anything that is not meant to be there. this being the reason you should regularly change your oil. hope that helps.
snug them don't tighten them
Battery
This depends on the model we are talking about. The weight of the 2012 Honda Rebel CMX250C is 331 pounds with fuel and ready to drive. The Honda Rebel CMX 450 from 1986 weighs 383.6 pounds dry weight, without fuel and oil. The Honda CA Rebel 125, the 2000 model, weighs 302 pounds dry weight.
it is located between the rear fenders
honda wave and honda xrm is same engine,.. it depends on the driver but xrm and wave is beaten by my kawasaki aura,..
under the seat next to the battery
if its an electric start its probably in need of a new battery my xr 125 had the same problem and just had it changed and all is working fine hope that helps
for the relay switch 6volts, for the battery... dunno- mine's a 250 and uses an ATV battery.. I think they're 12 volts.
yes but the honda cr 125 is a 2 stroke
You cant find replacement parts for that bike, but if its for a piston... a honda CR 125 dirt bike piston will help and fit, heights and dimensions are to the notch the exact same...
The mixture would be 20 to 1 for a Honda 125 2 stroke
