Frequently Asked Questions

What's the horsepower gain over a stock Touring engine?

S&S T124 engines deliver significantly more horsepower and torque than factory stock. Exact numbers depend on your Touring year and transmission setup.

Will this fit my Harley Softail?

No — T-series engines are not compatible with Softail models. S&S makes different engine platforms for Softails.

Can I install this in a Tri-Glide or trike conversion?

Is installation difficult?

Engine installation requires professional shop expertise, proper tooling, and routing of electrical, fuel, and cooling lines specific to your Touring model year. Plan for a multi-day installation.
