Universal solid state rectifier.12 or 6 volt.+ or - earth and rated at 35amps which is about 25 amps more than your alternator can make.Suitable for single phase alternator equipped bikes.This is the correct part number for your 2 wire alternator equipped bike.Some sellers are supplying  similar looking rectifiers,however,if they are selling them cheaper than mine,i suspect they will be the low cost KBPC 5010.If you buy that type,and the seller usually hides the part number,be prepared for some odd electrical behaviour later on,and invest in breakdown cover.The part i sell is the type that has been tried and tested for many years and is the industry tested item.If you check part numbers on the pictures,you will notice all the quality sellers with knowledge,will only supply KBPC 3504.Beware of any advert hiding the part number. A drawing showing connections to the rectifier will be included.Posted the same day as payment received by First class post.Thats as fast as i can get it to you.
