Spyke 1.4 KW Hi-Torque Starter For Harley Big Twin 1986-1988
Spyke 1.4 kW Hi-Torque Starter: Modern Cranking for Early Evolution Big Twins
The Spyke 1.4 kW Hi-Torque Starter is the premier performance upgrade for Harley-Davidson owners riding the first generation of Evolution Big Twins (1986–1988). During this era, factory starters often struggled to provide enough torque for consistent hot restarts, especially as engines were modified for more power. Spyke solves this with a 1.4 kilowatt motor that provides a 46% increase in cranking torque, ensuring your Shovelhead-to-Evo transition era bike fires up with authority.
Advanced Supertorque Gear Reduction
The secret to Spyke’s legendary starting power is its internal gear reduction technology. By utilizing a specific gear ratio to multiply the motor’s force, this starter generates significantly more rotational torque at the primary drive than the original equipment. This mechanical advantage allows it to overcome the heavy resistance of high-lift cams and big-bore cylinders without the “stalling” or “labored” sound common in older stock starters.
Efficiency That Preserves Your Battery
Despite its massive power output, the Spyke 1.4 kW unit is engineered for low-amperage draw. It maximizes every bit of energy from your battery, leaving more voltage available for your ignition system during the cranking cycle. This results in a hotter spark and faster ignition, which is critical for carbureted Evolution engines. It provides high-output performance without immediately requiring a specialized high-CCA battery.
Rugged Construction for Long-Term Reliability
Built to handle the extreme vibration and heat of a vintage V-Twin, the Spyke starter features industrial-grade solenoids and reinforced internal windings. The unit is housed in a compact, sleek body that fits perfectly in the factory location, maintaining the classic look of your 1980s Big Twin while providing modern, professional-grade reliability. Each unit is manufactured to exacting standards to ensure a long service life under the harshest riding conditions.
Fitment and Compatibility (1986–1988)
This starter is designed as a direct replacement for the specific 5-hole mounting configuration used on:
- Harley-Davidson Softail (1986–1988): Heritage, Custom, and Standard models.
- Harley-Davidson Touring (1986–1988): Electra Glide, Tour Glide, and Road King precursors.
