2020 Harley-Davidson Street 750 Overview
Harley-Davidson Street 750 is a custom / cruiser motorcycle, displacing 749 cc. Power comes from a V2, four-stroke engine running Single Overhead Cams (SOHC) valve actuation, a compression ratio of 11.0:1. Bore and stroke come in at 85 x 66 mm. On the performance side, it delivers 60.3 Nm @ 4000 Revolutions of torque. On the road, the 2020 Street 750 tips the scales at 233.2 kg, carries a 13.10-litre fuel tank, offers a seat height of 653 mm and spans a 1534 mm wheelbase. That's roughly 67.4 kg lighter than the average custom / cruiser motorcycle in our database. The full 2020 Harley-Davidson Street 750 spec sheet below covers every technical detail, from suspension travel to tyre sizes.
2020 Street 750 - Pros & Cons
Strengths
-
🔧
Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.
-
📏
Accessible seat height: A 653 mm seat height keeps this manageable for most riders, which helps confidence at parking-lot speeds.
-
⚙️
Low-maintenance final drive: Running Belt (final drive) final drive cuts out the regular chain cleaning and tensioning that most bikes need.
Considerations
-
ℹ️
Age-related wear: Nothing specific stands out as a weak point on the Street 750 - the usual used-bike checks (service history, consumables, tyres) apply.
Wear Points & Servicing Notes
Fuelling & injector care
The fuel injection on the Street 750 needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.
Valve clearance checks
With Single Overhead Cams (SOHC) valve gear, the Street 750 needs periodic clearance checks; caught early they're a cheap adjustment, left unchecked they accelerate valve seat wear.
Brake disc and pad wear
Braking up front comes from Single disc. 2-piston floated, optional ABS - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.
Suspension condition on used examples
The Street 750's suspension runs Telescopic fork at the front. The rear uses Twin shocks. Fork-seal condition and rear linkage play are the two things worth checking before buying used.
Final drive maintenance
The Street 750 runs belt final drive: no lubrication or frequent adjustment like a chain, though belt tension and wear are worth a periodic look.
Handling the weight at a standstill
233.2 kg puts the Street 750 toward the heavier end of its class. It's most noticeable at walking pace; once underway the mass settles into the handling rather than fighting it.
Street 750 - Buying & Maintenance Guide
What to check before buying
Before handing over money for a used 2020 Harley-Davidson Street 750, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy Street 750 should catch quickly and settle into a smooth idle.
Oil and filter changes
Nothing protects a Street 750's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). The sump holds 3.10 litres, so budget for that volume of quality motorcycle-specific engine oil. Match the viscosity grade to what the owner's manual specifies, not what's cheapest.
Fuel system care
Fuel injection on the Street 750 needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.
Valve clearance service
Valve clearances are easy to overlook on a used Street 750 since a bike out of spec doesn't always feel obviously wrong - but the wear it causes is real. Ask the seller for documentation before assuming it's been done.
