RK Motorcycle Chains, Connecting Links and Chain and Sprocket Kits

Nearly every RK listing is a drive chain or something that joins, cuts or replaces one, so the choice comes down to pitch, link count and chain series. We list about 625 RK products: roughly 380 chains and 145 chain and sprocket kits, with the rest connecting links and tools. Most are in Final Drive Belts & Chains, and connecting links and kits sit in Other Belt, Chain & Sprocket Parts. A small group is filed under UTV | ATV.

RK Europe's site describes the company as a power transmission maker since 1951 and an OE manufacturer since 1961.

Chains by series

Titles state the pitch first (420, 428, 520, 525 or 530), then the series, the link count and sometimes a color. About 150 titles are 520, about 135 are 530 and about 90 are 525, with smaller 420 and 428 groups.

Standard and heavy-duty. The M series covers the standard and heavy-duty chains: the M520 heavy-duty, 110 links, the M530 standard, 120 links, the M525 standard, 110 links, the M420 standard, 112 links and the M428H heavy-duty, 120 links.

Max O, Max X and Max Z. These three series run in 520, 525 and 530, and many come in colors such as gold, black/chrome and black/gold. Examples are the 525 Max O, 130 links, the 520 Max X in green and the 530 Max Z in gold, 160 links.

ZXW, XRE, EXW and XRU. The 530 ZXW in black scale, 170 links, the 530 ZXW in green, the 520 XRE, the GB 520 EXW and the 520 XRU in gold are listed under their own series names.

Dirt and racing. The MXZ line covers the 420 MXZ4, 428 MXZ1 and 520 MXZ5, and the 520 MXU is titled a sealed racing UW-ring chain. About ten listings are drag racing chains, such as the 530 ProDR, 130 links and the 530 DR, 150 links.

Chain and sprocket kits

About 145 kits pair a chain with sprockets for one bike. The kit type is in the title: OEM Replacement (about 75), Quick Acceleration (about 50) and 520 Aluminum Race (14), with a few Black/Natural kits. Suzuki, Yamaha, Kawasaki and Honda have the most, followed by Triumph and BMW. Examples include the Yamaha YZF-R1 OEM kit, the BMW S 1000 R kit for '14-'20, the Kawasaki ZX-6R/6RR kit for '05-'06, the Suzuki GSX-R 1000R Quick Acceleration kit in gold, the Honda CBR 1000 RR Quick Acceleration kit, the Honda CBR 1000 aluminum race kit and the Triumph Speed 400 kit.

Connecting links and tools

About 90 listings are connecting links, split between clip and rivet versions and matched to a series by name, such as the 520 MXU clip link and the 530 ProDR link. Tool listings are the riveting, press-fit and cutting chain tool kit and a replacement cutting pin.

Matching an RK part

Read the pitch and link count first, then the series. Connecting links are named for a series, so match the series in the link title to your chain, and compare your current chain's pitch before ordering. Kits name the bike. Our chain size chart covers chain sizes.

RK questions

How do I find my link count? The count is in each chain title, such as 110, 120 or 130 links. Compare it with your current chain.

Does a chain come with a connecting link? Links are separate listings, so read the title for what is included.

Are sprockets sold with the chain? Only in the chain and sprocket kits. Plain chains are chain only.
