520-110 O-Ring Drive Chain for Yamaha TTR250

This 520-110 O-ring drive chain is a replacement drive chain for the Yamaha TTR250, built to transfer power from the countershaft sprocket to the rear wheel with sealed lubrication.

Overview

This 520-110 O-ring drive chain is a direct-fit replacement for the Yamaha TTR250 produced between 2001 and 2006. The chain uses O-ring seals to hold grease inside the rollers, which reduces wear and stretches out service intervals for trail riders and weekend trail bikes. It suits riders replacing a worn or stretched chain on a TTR250 and wanting dependable power transfer without constant adjustment.

Built For Performance

• 520 pitch sizing matches the TTR250 countershaft and rear sprockets
• 110 link count fits the stock TTR250 chain length
• O-ring seals retain lubricant and block out dirt and grit

Good To Know

Q: Does this chain need a master link to install? A: Yes, a 520 chain of this type is joined with a master link, so confirm the link is included with your order and match it to the chain pitch. Q: How often should an O-ring chain be adjusted? A: Check tension before each ride and adjust to the free-play figure in your TTR250 service manual, since a chain that is too tight wears sprockets and bearings faster.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
