Will I need a longer chain with a swingarm extension?

Yes, in most cases a longer chain is required when installing a swingarm extension or extended swingarm. Increasing the wheelbase moves the rear axle farther back, which requires additional chain length to properly reach the rear sprocket while maintaining correct adjustment range.

The amount of additional chain needed depends on the length of the extension, sprocket sizes, axle position, and motorcycle model. Small extensions may only require a few additional links, while longer drag racing setups may require a completely different chain length.

It’s important to properly size the chain and verify axle adjustment after installation to maintain correct chain tension, alignment, and drivetrain performance.
