Early Twin Cam models (including some 2007) can experience wear on the hydraulic cam chain tensioners. Replacement with upgraded hydraulic tensioners or the Screamin' Eagle cam plate/tensioner upgrade is recommended.
Stiction In Forks:
Some Dyna models may experience fork stiction due to internal seal or bushing wear. Regular fork oil changes and proper maintenance help mitigate this.
Primary Bearing Wear:
While less common than on earlier models, checking primary bearing runout and condition is part of good maintenance.

Dyna Lineage:
The Dyna line was introduced in 1991 and was characterized by its traditional styling, rubber-mounted engine for reduced vibration, and dual rear shock absorbers. It served as a bridge between the rigid-frame Sportster and the Softail's hidden rear suspension.
2007 Updates:
The 2007 model year saw the widespread adoption of the Twin Cam 96B engine across the Dyna range, replacing the previous Evolution Big Twin. This brought increased displacement, power, and a 6-speed transmission as standard.
Manufacturing Location:
United States (various Harley-Davidson assembly plants).
Production Period:
The Dyna platform was produced from 1991 to 2017, after which it was succeeded by the Softail platform with significant chassis changes.
