We will work with you to get the best results for your budget.

We have been building performance engines for Harley-Davidson motorcycles for 15 years and have seen the need for Kits to suit the Riders needs not just a one size fits all approach.

Horsepower figures get attention.

Time slips earn respect.

At APE, we’re proud of our dyno results, but we believe the real test starts once the bike leaves the dyno room.

Whether it’s a basic cam package on a factory displacement engine or a 200+ horsepower big-inch build, our philosophy never changes:

Build combinations that perform where it matters.

That’s why we continue to take our bikes to the drag strip.

Not because we have to…
Because we want to prove our combinations work in the real world.

Three factory displacement Harleys.
Three camshaft and bolt-on combinations. Three genuine 10-second motorcycles.

✔️ Factory 114” Low Rider S – APE/CR 483
10.86 @ 123mph

✔️ Factory 117” Fat Boy – APE/CR 484
10.86 @ 120mph

✔️ Factory 114” Fat Bob – APE/CR 485
10.68 @ 120mph

Anyone can debate dyno numbers.

Very few are willing to line their bikes up at the track and let the time slip do the talking.

We’ll keep building them.
We’ll keep racing them.
And we’ll keep backing up our results.

Real performance. Proven performance.
