Triumph Street Triple RS: Keeping Your 765cc Triple in Peak Condition

The Triumph Street Triple RS, a jewel in Triumph's middleweight line-up, is renowned for its exhilarating performance and sharp handling. Since its 765cc engine debut in 2017, evolving to offer more mid-range torque and Euro 5 compliance by 2020, this machine demands regular attention to maintain its sporting prowess. Whether you're a seasoned mechanic or a new owner eager to dive into the world of motorcycle maintenance, understanding the service schedule is paramount. This guide will walk you through everything you need to know to keep your Street Triple RS performing at its best.

Understanding Your Service Intervals

Triumph specifies a consistent service interval for the Street Triple RS: every 6,000 miles (10,000 km) or annually, whichever comes first. This primary service is crucial for the overall health of your motorcycle. Beyond this, specific components require attention at different intervals.

Key Service Milestones:

• Every 6,000 miles / 10,000 km (or Annual): This is your standard service. It includes an engine oil and filter change, along with a comprehensive list of checks.
• Every 12,000 miles / 20,000 km: At this milestone, in addition to the standard service items, you'll need to replace the spark plugs and air filter. This is also when the crucial valve clearances are checked and adjusted if necessary.
• Every 24,000 miles / 40,000 km: Triumph recommends replacing the fork oil at this interval to ensure optimal front suspension performance.

It's important to remember that the Street Triple RS is a sportbike with a chain drive. This means regular attention to chain condition and tension is vital. Furthermore, your brake fluid and coolant should be serviced periodically to ensure safety and prevent corrosion.

What You'll Need: Essential Consumables and Tools

Before you begin any maintenance, ensure you have the necessary tools and consumables. Having the right parts on hand will make the process smoother and more efficient.

Specific Consumables for the Triumph Street Triple RS

Using the correct specifications is crucial for engine longevity and performance.

General Motorcycle Maintenance Consumables and Tools

Don't forget these essentials:

• Paddock Stand: Indispensable for easier chain maintenance and other servicing tasks.
• Chain Lube: Motul chain paste is highly regarded for its staying power and minimal fling. Consider the Motul chain care kit for a complete package.
• Grease: Lithium soap-based grease is excellent for lubricating external pivot points like the swingarm and bearings.
• Cable Lubricant: Protect All Cable Life is ideal for lubricating your cables and controls.
• Basic Toolkit: Ensure you have essential tools such as a paddock stand, oil filter wrench, torque wrench, socket set, and screwdrivers.

Daily Checks: Your Pre-Ride Routine

A quick check before every ride can prevent minor issues from becoming major problems. Make these checks a habit:

Chain Maintenance: The Key to Drivetrain Longevity

Your Street Triple RS's chain and sprockets are critical components. Neglecting them can lead to premature wear and potential failure. Triumph recommends the following:

• Lubricate chain: Every 200 miles (300 km).
• Check chain wear: Every 500 miles (800 km).

Checking Chain Wear: To check for wear, hang a 10-20 kg (20-40 lb) weight on the chain. Measure the length of 20 links on a straight section of the chain (from the 1st to the 21st pin). Repeat this measurement in a few different spots. If any section exceeds 319 mm (12.6 inches), the chain and sprockets should be replaced.

Checking and Adjusting Chain Slack:

Chain slack is the free vertical movement of the centre part of the bottom chain segment. For Triumph motorcycles, the target slack is 20-30 mm (0.8 – 1.2 in).

How to Check Slack:

1. Place the motorcycle in neutral on a level surface.
2. Elevate the rear wheel using a paddock stand.
3. Rotate the wheel to find the tightest part of the chain.
4. Gently push the chain up and down with your finger to measure the deflection (slack).

How to Adjust Slack:

1. Ensure the rear wheel is elevated.
2. Loosen the rear axle nut.
3. Loosen the lock nuts on the adjuster bolts on both sides of the swingarm.
4. Turn the adjuster bolts. Turning counter-clockwise extends the bolt, lengthening the chain and making it tighter. Turning clockwise retracts the bolt, loosening the chain.
5. Ensure adjustments are made equally on both sides, using the markings on the swingarm as a guide.
6. Tighten the adjuster lock nuts to 15 lb-ft (20 Nm).
7. Tighten the rear axle nut to 81 lb-ft (110 Nm).
