Q. Which is best Apache RTR 180 or Pulsar 180?

Pulsar 180 certainly will have engine issue after some time, the build is so so and tourque is less. where Apache engine is excellent, much refined, fast between 0km to 60km speed, better pickup, great riding position, ABS (life saving) and long run due to built quality. Anytime on Apache RTR 180, I am a proud owner of Apache.Do check my motovlog channel in youtube, done my travelling in whitle Apache RTR180.https://www.youtube.com/watch?v=md3Ldvs1OwU

Both are performance bikes but Apache 180 RTR should be the 2021 model, not the older version.

I would say apache rtr would be ok as TVS bikes do not need much maintenance costs provided the maintenance is taken care of !)
