When it comes to motus aftermarket parts, quality and precision matter—especially if you want sharper control, reduced weight, and a finish that makes your Motus stand out.
This article highlights 16 essential upgrades for MST and MSTR owners who expect more than stock—covering expertly engineered carbon fiber, performance electronics, and braking components, each chosen to elevate both performance and style without sacrificing reliability.
1. Motus High Output Ignition Coil Upgrade
Leveling up your Motus V4’s firepower starts at the spark. Stock coils leave some throttle response on the table, especially as you pile on mods. Upgrading your ignition coil means more reliable combustion and sharper response. No guesswork here. We recommend direct OEM replacement kits for MST and MSTR (2015–2017). Get plug-and-play install, no splicing or hunting for odd connectors. Always match the wiring harness and connector lengths—don’t settle for a “universal V4” coil when one designed for the Motus harness exists.
- You get:
- Stronger, consistent spark even under hard acceleration or heat soak.
- Smoother idle and stable ignition at every rpm.
- Confidence in factory warranty terms when installed right.
Pro tip: Always ask vendors for Motus-specific validation—not just generic ignition claims. True Motus fitment means correct dwell specs and no check-engine surprises. We’ve seen firsthand that using the right coil locks in daily reliability, even after boosting airflow or adding tuning.
2. Custom Performance Spark Plug Wires for Motus V4
Your coil is only as strong as the wires feeding spark. Weak leads or poorly-sealed boots leak power and invite misfires, especially with high-powered coils. Step up to custom stainless-core wires with EPDM insulator and silicone jackets, matched to the exact routing and length Motus needs. It’s the first move before any ECU work or plug changes.
Compare for optimal results:
- Resistance (ohms per foot) and temp rating
- Proper fit boots (angled or straight), robust terminal locks
- Motus-specific wire lengths for perfect harness fit
The result: Consistent spark at high load and heat, less risk of crossfire, and reliable ignition performance at every rpm. We’ve seen routes chafe wires or bake them against headers. Choose labeled, stress-relieved kits to cut setup headaches and avoid guessing mid-tune.
3. Brisk Premium LGS Spark Plugs for Motus MST and MSTR
Changing plugs isn’t just routine maintenance. The right plug pulls more from every coil upgrade. Brisk Premium LGS with silver electrodes and 360-degree semi-surface discharge design require less ignition voltage, deliver a faster flame kernel, and stay reliable under heat-soak or hard runs.
What you gain:
- Improved cold start, less knock, and sharper throttle even when things get hot
- Lower required voltage, so your ignition system works easier and lasts longer
- Correct thread reach, heat range, and gap for Motus heads
Check install fit against vendor photos and keep a spare set for validation runs post-change. Always check the recommended torque values; don’t rely on “tight enough.”
4. Magura HC3 Radial Front Brake Master Cylinder 15 mm
A performance Motus build should stop as confidently as it goes. Radial master cylinders like the Magura HC3 15 mm deliver shorter, more controlled stops with a firmer lever and precise feedback. Use CNC machined, ABE-approved assemblies with 3-way lever adjustment for maximum grip and predictable bite.
Most important:
- Matched bore size (15 mm) for dual front calipers on Motus sport-touring frames
- Remote reservoir and included hardware for easy install
Be smart: Confirm caliper piston area before committing. Master-cylinder upgrades transform braking, but only when matched. Always ask for lever ratio details and, if using ABS, get confirmation of compatibility for a safe upgrade.
5. Braided Stainless Steel Brake Lines for Firmer Lever Feel
You can’t have predictable braking if your lines bulge. Replace aging rubber with PTFE-core, 304 stainless braided lines for a firmer, more consistent lever at every stop. A full kit reduces fade on descents and delivers instant pressure right where you need it.
Checklist:
- Motus-specific length, perfect banjo fit, and pressure-tested above 3,000 psi
- Replace front and rear as a set, using new high-boil DOT 4 fluid
- Request hydraulic test certs where offered for extra peace of mind
Bleed, test, and recheck for leaks after install. Modern brake lines matter as much to your ride feel as pads or rotors—don’t skimp.
6. Performance Brake Rotors Matched to Pad Compound
Brake rotors play a bigger role than most expect. Go for high carbon or certified alloy steel rotors. These disperse heat and resist cracking under aggressive use. Precision machining and the right venting pattern prevent noise and premature wear.
Always:
- Match rotor metallurgy to your chosen pad compound
- Cross-check bolt spacing and rotor thickness before install
Rotor upgrades are a foundation. Avoid universal parts that “should fit.” Only OE-grade, model-matched rotors keep noise low and fade away—even on the tightest mountain runs.
7. Adjustable Rearsets for Ergonomics and Ground Clearance
Rearsets aren’t just for track days. They give Motus owners fine-tuned control over rider triangle and body position, crucial for aggressive canyon rides or long stints. Look for kits with multiple peg locations, hardened bearings, knurled pegs, and plenty of adjustment.
Key reminders:
- Double-check heel guard and shift linkage clearances before dialing in position
- Never trade long-term comfort for a race-only stance. Balance is key.
Test full linkage motion after install. Retain proper brake light function and choose kits that include all hardware—no improvising required.
8. Frame Sliders and Protection Hardware
Protect your Motus investment. Frame sliders absorb abrasion from a tip-over or low-speed drop. Always bolt through solid subframe points and use impact-resistant polymer pucks for best results.
Choose:
- Through-bolt mounts, not thin, bracket-only designs
- Large-diameter pucks that clear exhaust and fairings
Extra smart: Look for kits with replaceable inserts and check for luggage rack compatibility. On a rare platform, protection pays dividends in saved bodywork and downtime.
The best Motus builds start with proactive defense, not recovery from an avoidable drop.
9. Fender Eliminator Tail Tidy With Legal Visibility
A clean tail transforms your Motus’ style. Use a stainless or aluminum tail tidy with LED plate light, proper turn signal spacing, and vibration isolation. Confirm legal plate angle and illumination for your area. If you ride with trunk luggage, double-check mounting compatibility before you buy.
Look for:
- Integrated lighting that avoids hyperflash and wiring headaches
- Kits with vibration-resistant hardware to keep things solid, even on rough pavement
Read reviews and specs to dodge hassle, ugly plate brackets, and botched installs. The right tail tidy modernizes your Motus look without losing visibility or legality.
10. LED Auxiliary Lighting for Night and Weather Confidence
When the sun drops or the weather turns, great lighting keeps you in command. Auxiliary LEDs brighten the path and boost your visibility from every angle. Wide-beam, weatherproof systems with adjustable mounts are the gold standard for Motus riders who refuse to cut corners on safety.
- Smart moves:
- Choose beam patterns for your riding: driving for highway, flood for winding roads.
- Confirm mounting space before ordering.
- Always use relay harnesses to isolate your electrical system.
Check your charging system’s capacity before installing high-output lights. The right LED upgrade creates confidence in every condition you face—while giving your Motus a distinctive look after dark.
11. Performance Exhaust System for Voice and Flow
A performance exhaust unlocks the Motus V4’s true character. Boost throttle response, cut weight, and let the engine voice shine—without droning or drowning out comfort. Prioritize systems with precise O2 sensor placement and durable packing to stand up to miles of heat.
- Get this right:
- Match O2 sensor bungs to your Motus spec.
- Confirm heat clearance for luggage and center stands.
- Pair any major intake or exhaust changes with careful tuning.
Double check header pipe diameter and sensor threads before install. Ask for real dB numbers at known rpm, not just “sporty sound.” A mismatched exhaust costs you power, comfort, and legality.
12. ECU Calibration Strategy: Remap vs Piggyback
Your Motus only hits peak performance when airflow, ignition, and fueling are integrated. That means a proper tune. Whether you pick ECU remapping or a piggyback system, real gains come from tuners with Motus V4 expertise—not someone chasing peak dyno charts.
- Steps for results:
- Upgrade coils, plugs, intake, and exhaust first.
- Run baseline logs before touching the map.
- Ask for recovery options and review real-world logs, not just claims.
A flat, “race” table can create more headaches than gains. Demand datalogs that show correct fueling, knock control, and adaptation. Insist on post-tune validation on the street, not just the dyno.
13. High Flow Air Filter and Intake Duct Optimization
Improving intake flow pays off in throttle response and fueling stability. Select dry synthetic filters for clean sensor operation or oiled cotton gauze for max airflow—just don’t over-oil if a MAF is in play. Sealed airboxes and smooth ducting reduce turbulence and keep intake temps low.
- Installation keys:
- Verify airtight seals.
- Keep all OEM sensor locations intact to avoid adaptation errors.
- Use smooth-radius couplers for steady airflow.
Monitor trims after install and avoid big leaks—small sealing errors lead to inconsistent gains that mask real improvement. Upgrading the intake should feel like a crisp, obvious step up, not a “maybe.”
14. Cooling System Hoses and Heat Management
Long rides expose every weakness in your cooling system. Silicone hose kits resist pressure and daily heat cycles better than old rubber. Fresh clamps and OEM-compatible routing guard against leaks that can sideline a trip. Radiator guards help fend off debris without sacrificing flow.
- Cooling musts:
- Swap to aluminum-safe coolant with proper inhibitors.
- Use high-integrity clamps, not worn-out factory pieces.
- Pressure test after install.
For Motus, check that hoses clear headers and frame edges. If you use heat wrap, apply it only where absolutely necessary to avoid over-insulating the system.
15. Performance Brake Pads and Stainless Hardware
Pads define initial bite, fade resistance, and rotor life—select compounds to match your riding. Street-sport offers low dust and daily control; aggressive compounds favor temperature range and stopping power.
- Key fitment:
- Always pair pad compound to rotor metallurgy.
- Upgrade to stainless pad pins and anti-rattle hardware for consistency.
Use a strict bedding-in process, not guesswork. A change in pad or hardware can elevate your stop-to-stop consistency, which keeps confidence high when pushing hard.
16. Carbon Fiber Bodywork and Protection Enhancements
You want performance and presence—carbon delivers both. Pre-preg, autoclave-cured pieces save real weight and add stiffness across the Motus chassis. Fitment must be precise to prevent vibration or cracking. UV-stable clear coat maintains that deep, glassy look for years.
Here at ASM Design, our carbon engineering uses pre-preg layups and autoclave curing to guarantee high strength-to-weight and long-term clarity. This is non-negotiable for top-tier builds. Insist on the same when shopping Motus upgrades.
- Always:
- Get OEM-matched mounts and edge protection.
- Confirm weight savings claim versus stock.
- Keep old panels as references for tweaks.
High-impact zones like belly pans and heel guards deserve carbon protection. This isn’t just style. It’s security for every mile.
