1. I am sure you have papers to show that this ' cutting out' problem was attended by the manufacturer during the period of warranty/guarantee.

2. if that is so and if the servicing was done on multiple times for the same reason which has not be repaired even today then it is a good case of deficiency in service of the manufacturer.

3. In that event you can file a case before the consumer forum wherein you can seek bot damages and compensation for the manufacturing fault as well for the agonies and threat to life caused by the vehicle.

It is risky to drive such a bike when it cuts out on turns 

2) issue legal notice to manufacturer to rectify the defect 

3) if manufacturer fails to do so file complaint before consumer forum seek orders to direct manufacturer to replace the bike or refund your money 

4) also seek litigation costs and compensation for mental torture undergone by you 

Sir if service centre is enable to find the fault after giving time again on service it is better to write to the company itself that is to service department of manufacturer to look into the issue and they can with the help of there Research and development team along with service technician of company can find default.

You can go to consumer court for refund of the same along with compensation. First send a legal notice to them

Yes, file immediately a complaint before the Consumer Forum for the relief stating all the things what you have mentioned.

Issue a legal notice through an advocate and file complaint before consumer forum under deficiency of service and claim compensation. 

Dear Sir,

If warranty period completed it is very hard to claim compensation from the dealer.  However to know their stand you may get issue a legal notice and fix responsibility on the dealer and manufacturer for selling faulty vehicles which do not sustain for long runs thus they cannot stink their responsibility in payment of compensation.  Be aware that you may also file complaint with consumer forum and manufacturer  and dealer always afraid of negative publicity and you can get compensation easily.

Have you appraised the dealer about your findings of the fault of bike and sought to inspect and test the vehicle from that angle?

Given the bike has crossed the warranty period as well, you cannot drag the company to the consumer forum too.

You may contact the company directly and appraise them about the problems you had been facing from the beginning and request them to direct the expert mechanic or technician to have a look at it and detect the actual problem and rectify the same.

Let the company answer your problems.

Why don`t you file consumer complain against company and dealer for refund of amount for selling defective piece.

1. You shall have to file a consumer case before the local District Consumer Dispute Redressal Forum against the manufacturer and the dealer alleging deficiency in service and unfair business practice demanding refund of the entire consideration you had paid for buying the bike with interest, damage and cost.

2. Your stand should be that you had brought to the notice of the Company the fact of the manufacturing defect which they have not rectified even after several attempts and also the the Company has sold you a defective bike.

3. Engage a local lawyer having expertise in dealing with consumer cases.
