2015 Street 750 - 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.
Strong front braking: The single disc front brake bites hard and stays consistent - a solid foundation whether it's stock or upgraded with braided lines.
Accessible seat height: At just 653 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

Age-related wear: No particular mechanical concern flags for the Street 750 - 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 Street 750 comes from 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 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.

Final drive maintenance

Belt final drive keeps day-to-day maintenance minimal on the Street 750 - just periodic tension and wear checks rather than the regular cleaning a chain demands.

Handling the weight at a standstill

The Street 750's 221.8 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.

Street 750 - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2015 Harley-Davidson Street 750 custom / cruiser should cover the same ground every time: service history, drivetrain condition, and any oil seepage around the casings. This model runs belt final drive, so check belt tension and tooth wear - a cracked or glazed belt is a clear sign of neglect. Now 11 years old, this custom / cruiser is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Start it from cold if you can - a well-kept Street 750 settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for the Street 750's v2, four-stroke engine - keep to the manufacturer's interval rather than stretching it. The sump holds 3.10 litres, so budget for that volume of quality motorcycle-specific engine oil. With an 11.0:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Use the viscosity grade the manual specifies, not whatever's on sale.

Fuel system care

Injector systems like the Street 750's hold up well with basic care - decent fuel, an occasional cleaner additive, and draining old fuel before any layup longer than three months.
