  2. Brake Master Cylinder Reservoir Cap - 43513- 5 Star Review

    Posted by on 24th May 2018

    Perfect replica and good quality product.

  3. Extremely Well-crafted 5 Star Review

    Posted by on 7th Dec 2014

    I purchased this cap for my '71 CB450 twin and, while the graphics are slightly different from the original, it looks fantastic! Frankly, it's probably nicer than the original cap was when new.

    I've placed a few orders with 4into1, and the service has consistently been brilliant!

  4. Very nice replacement 5 Star Review

    Posted by on 27th Aug 2014

    My CB350 before I got it was unfortunately used and abused. The master cylinder was scraped and looked like crap. This replacement looks amazing.

  5. Great Service 5 Star Review

    Posted by on 7th Feb 2014

    I live in Australia and was hesitant to buy. I will definitely purchase my parts from 4 into 1 from now on as postage service is great, parts list is great and also a lot cheaper than ebay sites. Delivery time to half a world away was fantastic.
