Jims Instruments

7 products

Jims' presence in the Instruments category is on the mechanical drive side rather than the gauges themselves — speedometer drive gears, drive housings, and the close-tolerance transmission outputs that turn rear-wheel rotation into a reading on the dash. As a brand built on specialist tools and precision engine internals exclusively for Harley-Davidson V-twin platforms, Jims applies the same machining standards to drive gear work as they do to lifters, pushrods, and bearings. Speedometer drive gears wear, and an incorrectly installed replacement reads inaccurately or strips itself in short order — Jims components reduce that risk through dimensional consistency. Sportster, Softail, and Touring mechanics restoring accurate speedo function will find Jims drive gears the choice that aligns with the rest of the precision-engineered drivetrain. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks Jims as part of the comprehensive range for serious Harley-Davidson workshop work.
