2023 Street Triple RS - Pros & Cons

Strengths

Strong power output: 2023 Triumph Street Triple RS makes 128.2 hp @ 12000 rpm with 80 Nm @ 9500 rpm of torque - competitive figures for its class.
Fuel injection: The Multipoint sequential electronic fuel injection with electronic throttle control system delivers crisp throttle response and reliable cold starts regardless of altitude or temperature.

Considerations

Tall seat height: The 836 mm seat height will challenge shorter riders - tiptoeing at low speeds is something to factor into your decision.
Chain final drive upkeep: Chain final drive needs regular cleaning, lubrication and tension checks to get full life out of the sprockets.

Wear Points & Servicing Notes

Cooling system servicing

The Liquid-cooled system on the Street Triple RS needs a coolant change roughly every two years (or per the service schedule) - skipping it lets the coolant turn acidic and corrode the aluminium water passages over time.

Fuelling & injector care

Fuelling comes from Multipoint sequential electronic fuel injection with electronic throttle control. Systems like this are largely maintenance-free beyond keeping fuel quality decent and injectors clear - a fuel-system cleaner every service interval is cheap insurance.

Brake disc and pad wear

The 2 x 310 mm floating discs, Brembo Stylema 4-piston radial monobloc calipers, OC-ABS, Brembo MCS radial master cylinder front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.

Suspension condition on used examples

Up front, the Street Triple RS runs Showa 41 mm upside down Big Piston Forks and Öhlins STX40 piggyback reservoir monoshock, adjustable compression and rebound damping, and preload adjustment at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.

Final drive maintenance

Final drive is by chain - expect to clean and lube it every few hundred kilometres and check tension regularly; a neglected chain wears the sprockets faster than the chain itself.

Frame & chassis check

The frame is Aluminium beam twin spar frame with 2 piece high pressure die cast rear subframe - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.

Street Triple RS - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2023 Triumph Street Triple RS, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained Street Triple RS should fire up cleanly and settle to a smooth idle within a few seconds.

Oil and filter changes

Regular oil changes are the single most important maintenance task on any Street Triple RS. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.

Fuel system care

The Street Triple RS's fuel injection system is durable but benefits from quality fuel and the occasional use of a fuel-system cleaner additive. If the bike has been stored for more than three months, drain and replace the fuel to prevent varnish deposits in the injectors.
