You must know that a CIBIL™ score is actually a credit score. CIBIL™ is only one of the four credit bureaus in India, the other three being Equifax, Experian and High Mark. All these four bureaus are certified to give you a credit score that can be used to know if you are credit healthy. 

A credit score ranges from 300 to 900. A score above 750 is considered a good credit score and can ease the process of availing a bike loan with a low interest rates as you will be considered a trustworthy borrower. The higher you rank on your credit score, the more eligible you will be for favourable loan terms. You can avail a bike loan with a lower credit score, but it will be a challenging process and you could get high interest rates on your loan. A better suggestion would be to improve your credit score and then apply for a bike loan for favourable loan terms.
