2019 Harley Street Glide 107 Performance Upgrade NS

2019 Harley-Davidson Street Glide – Milwaukee-Eight 107 Performance Upgrade This 2019 Street Glide with the factory Milwaukee-Eight 107 engine received a bolt-on performance package that dramatically improves power delivery, sound, and throttle response – perfect for long-haul touring with extra attitude.

The owner wanted reliable, real-world gains without major engine work. This proven Stage 1.5 combo delivered exactly that.

Installed Components

• S&S 475C camshaft – torque-biased grind that wakes up the 107 for strong mid-range and smooth top-end breathing

• Bassani Road Rage 2-into-1 exhaust – superior flow and scavenging for the M8 platform

• Vance & Hines Fuelpak FP3 – app-based tuning with Bassani-specific maps for optimal air/fuel ratios

Everything installed cleanly: cam timed perfectly, exhaust fitted tight, and tuned via the FP3 for immediate, drivable results.

Proven Performance Gains on the Milwaukee-Eight 107 Real-world dyno tests and rider reports on this exact setup consistently show:

• 12-20+ rear-wheel horsepower (from ~90-95 stock to 105-115+ rwhp)

• 15-22+ lb-ft torque (stock ~110-114 lb-ft jumps to 130-138 lb-ft)

The biggest improvement hits in the 2,500-4,500 RPM range – effortless highway passing, stronger 6th-gear roll-on, and crisp throttle with zero surging. The Bassani 2-into-1 gives a deep, authoritative growl that’s aggressive yet tour-friendly.

This build (completed before the move to Nova Scotia) showcases the clean, effective performance work we’ve always specialized in – the same standards we apply to every Harley at HD Industries in Bear River today.
