NCB stands for No Claim Bonus. This is a discount awarded at the time of renewal to the policyholder in case he/she does not raise a claim in the previous policy period. NCB can be as high as 50% discount on the premium if any claims are not raised for 5 consecutive policy years. Thus, it is regarded as the highest discount one can get on the bike insurance premium.

Claim Free Years and No Claim Bonus:
After 1 Year: 20%
After 2 Year: 25%
After 3 Year: 35%
After 4 Year: 45%
After 5 Year: 50%

Pro Tip: NCB belongs to you, not your bike. The owner of the vehicle enjoys this discount. If the ownership has changed, it resets to zero.
