2020 XG 750 Street - 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 720 mm, flat-footing at a stop is easy for most riders - a genuine confidence builder for less experienced owners.
-
⚙️
Low-maintenance final drive: Belt final drive is about as close to maintenance-free as motorcycle drivetrains get.
Considerations
-
ℹ️
Age-related wear: No particular mechanical concern flags for the XG 750 Street - condition on any used example comes down to how well it's been looked after.
Wear Points & Servicing Notes
Cooling system servicing
With Liquid cooled, thermal management is largely automatic, but the coolant has a service life of its own - replace it on the manufacturer's interval to protect the water passages and thermostat.
Fuelling & injector care
Fuelling on the XG 750 Street comes from Mikuni Single Port Fuel Injection. Cold starts and throttle response stay consistent across altitude and temperature, the main practical edge over a carbureted equivalent.
Brake disc and pad wear
Single disc, 2 piston caliper 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 Non-adjustable 37mm forks up front and Spring-preload adjustable dual 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 XG 750 Street - just periodic tension and wear checks rather than the regular cleaning a chain demands.
Frame & chassis check
The Mild tubular steel w/ rectangular backbone chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.
Handling the weight at a standstill
The XG 750 Street's 233 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.
XG 750 Street - Buying & Maintenance Guide
What to check before buying
A pre-purchase check on the 2020 Harley-Davidson XG 750 Street 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 XG 750 Street settles to a smooth idle within seconds.
Oil and filter changes
Oil changes are the cheapest insurance you can buy for a XG 750 Street's engine - keep to the manufacturer's interval rather than stretching it. Use the viscosity grade the manual specifies, not whatever's on sale.
Fuel system care
Injector systems like the XG 750 Street's hold up well with basic care - decent fuel, an occasional cleaner additive, and draining old fuel before any layup longer than three months.
