2017 Harley-Davidson Heritage Softail Classic Overview

For 2017, Harley-Davidson offers the Heritage Softail Classic as a touring motorcycle. The 2017 Harley-Davidson Heritage Softail Classic is built around a V2, four-stroke engine running Double Overhead Cams/Twin Cam (DOHC) valve actuation, a compression ratio of 9.7:1. Internally, bore and stroke are 98.4 x 111.1 mm. Out on the road, the Heritage Softail Classic delivers 125 Nm @ 3000 Revolutions of torque. In everyday use, the 2017 Heritage Softail Classic tips the scales at 347 kg, carries a 18.93-litre fuel tank, offers a seat height of 690 mm and spans a 1,635 mm wheelbase. That's roughly 22.9 kg heavier than the average touring motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2017 Harley-Davidson Heritage Softail Classic spec sheet below.

2017 Heritage Softail Classic - Pros & Cons

Strengths

Fuel injection: No choke, no jetting, no altitude compensation to think about - fuel injection just works across a wider range of conditions than carburetion.
Accessible seat height: At just 690 mm, flat-footing at a stop is easy for most riders - a genuine confidence builder for less experienced owners.
Large fuel range: With a 18.93-litre tank, this isn't a bike you'll be stopping for fuel every hour - a real asset on longer trips.
Low-maintenance final drive: Belt final drive is about as close to maintenance-free as motorcycle drivetrains get.

Considerations

Age-related wear: No particular mechanical concern flags for the Heritage Softail Classic - condition on any used example comes down to how well it's been looked after.

Wear Points & Servicing Notes

Fuelling & injector care

Fuelling on the Heritage Softail Classic comes from fuel injection. Cold starts and throttle response stay consistent across altitude and temperature, the main practical edge over a carbureted equivalent.

Valve clearance checks

Valve clearances on Double Overhead Cams/Twin Cam (DOHC)-equipped engines like the Heritage Softail Classic's drift slowly with mileage rather than failing suddenly - sticking to the service interval keeps it a non-issue.

Brake disc and pad wear

Single disc. ABS. 4-piston. up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.

Suspension condition on used examples

Suspension duties are handled by Telescopic fork up front and Twin shocks at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.

Final drive maintenance

Belt final drive keeps day-to-day maintenance minimal on the Heritage Softail Classic - just periodic tension and wear checks rather than the regular cleaning a chain demands.

Handling the weight at a standstill

The Heritage Softail Classic's 347 kg kerb weight is worth factoring into how you handle it at a standstill - parking-lot manoeuvres need a bit more deliberate technique than on a lighter machine.

Heritage Softail Classic - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2017 Harley-Davidson Heritage Softail Classic should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. Start it from cold if you can - a well-kept Heritage Softail Classic settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for a Heritage Softail Classic's engine - keep to the manufacturer's interval rather than stretching it. The sump holds 3.30 litres, so budget for that volume of quality motorcycle-specific engine oil. Use the viscosity grade the manual specifies, not whatever's on sale.

Fuel system care

Injector systems like the Heritage Softail Classic's hold up well with basic care - decent fuel, an occasional cleaner additive, and draining old fuel before any layup longer than three months.

Valve clearance service

There's no reliable seat-of-the-pants way to tell if a Heritage Softail Classic's valve clearances are in spec - a light top-end tick is the only real warning sign, and by then some wear has already happened. Service records are the only proof.
