Can double disc brake be installed on front wheel of Yamaha YZF R15 V 2.0?
It can be done, installing double disc brakes is definitely a complex task but not impossible, but our advise to you is that you should not take on this type of modification unless you have the skills to do it correctly, so better you get a licensed machinist to do the precision work, or you could end up with brakes that are worse than previous one, so have a licensed motorcycle mechanic inspect and approve the work when completed. Use a new or remanufactured master cylinder designed for dual brakes, get the calipers rebuild properly and use new high-performance pads and new brake lines. Use only new parts, or the best used parts that you can find. Use high grade threaded fasteners, and check your brakes thoroughly and often.
