This crate engine makes your Harley feel like a race bike. The low-end torque is phenomenal, and it revs surprisingly high. The only downside is the fuel consumption—it’s thirsty, but hey, power comes at a price.

The power and performance are truly top-tier. Only reason I’m not giving 5 stars is the price—it’s definitely a premium product. But if you want bragging rights and serious muscle under the tank, you won’t be disappointed.

The engine itself is a beast, no doubt, but be prepared for additional upgrades. I had to replace my clutch and tune the suspension to handle the extra output. Also, expect to spend time dialing everything in perfectly. Performance? Outstanding. Plug-and-play? Not quite.
