  Primary Drive 428 C Professional Chain

  Leland in GA

  Better than I thought

  Replaced an o ring with this and has exceeded my expectations. Was worried about it stretching more that an oem chain. But overall it holds well.

  Primary Drive 520 ORH Gold X-Ring Chain

  Eric in NC

  Sexy and Strong

  I replaced the stock front sprocket 13 tooth with a 14 tooth and the rear stock 43 tooth with a 49 tooth to maintain the same gearing, but it provided some additional clearance for the swing arm. I needed a longer chain to cover the increase in circumstance from the larger sprockets. Not only does the chain look great, it has performed just as good. I use DuPont chain lube and have never had any issues with 1500~ miles. 10/10 would buy again when needed.

  Primary Drive Front Sprocket

  Eric in NC

  Durable and Effective

  I replaced the stock front sprocket 13 tooth with a 14 tooth and the rear stock 43 tooth with a 49 tooth to maintain the same gearing, but it provided some additional clearance for the swing arm. I’ve had both sprockets installed for 1500~ miles without any issues. 10/10 would buy again when needed.
