KAVLYR — F-550 / F-600 shuttle bus

For the groups an E-Series shouldn't carry

There's a gap between the standard shuttle and the big iron. Your groups have grown past 26 people, or your routes are long enough that you want heavy-duty running gear under them — but a full-size chassis is more bus than the job needs. The KAVLYR fills that gap.

Built on the Ford F-550 and F-600, the KAVLYR seats up to 36 passengers with real weight headroom to spare. The F-Series chassis is rated for harder duty than the E-Series: heavier axles, bigger brakes, more capacity margin when the bus is full of people and luggage. If your buses run full, run long routes, or run all day, that margin is the difference between a chassis loafing at its rating and one working at its limit.

Typical KAVLYR buyers: charter and tour operators running mid-size groups, universities and athletic departments, churches with large congregations, and shuttle operators whose passenger counts crept up until the E-Series stopped making sense.

KAVLYR questions, answered

When should I choose the KAVLYR over the MAVRYK?

When your groups are past 26 passengers, or when you want heavy-duty axles and brakes under a bus that runs full or runs long routes. The KAVLYR seats up to 35.

When should I step up to the STRATOS instead?

When you regularly carry more than 35 passengers, or you need maximum luggage capacity for tour and charter work.

What chassis is it built on?

Ford F-550 and F-600.

How long does a build take?

90–120 days from order. The 2026 average is 92 days.

Need a configuration you don't see? Most layouts are buildable. Talk to your dealer or call HLE at 574-343-2150.

Built the HLE way

Every KAVLYR carries the same construction: powder-coated steel cage, one-piece pressure-laminated sidewalls, 5/8" PerformMAX 500 subfloor, Impact Guard roof, in-house wiring harnesses with marine-grade connectors — and every single unit runs the rain booth and a 25-mile road test before delivery.
