Going on a week-long trail trip requires method. No point loading half the garage, but it's also impossible to find yourself in the middle of nowhere with a puncture and nothing to fix it. After several trips to Spain, Morocco and the Balkans, I've refined a pack that fits in 30 litres and covers 95% of problems on road and track. The rest is down to luck or a call to breakdown assistance.
Tools and mechanical parts: the bare minimum
The classic mistake: taking a complete toolbox. On a trail bike like the BMW F 850 GS or Yamaha Ténéré 700, the original toolkit is sufficient for 80% of common jobs. The rest must fit in a tool roll of 1.5 kg maximum.
Essential basic kit:
- Leatherman Signal multitool or equivalent (200 g, around €80)
- Set of 8 metric combination spanners 8 to 19 mm
- Long Allen keys 4, 5, 6, 8 mm
- Magnetic Phillips and flathead screwdrivers
- 250 mm slip-joint pliers
- Spark plug socket with spare washer
- Valve core remover
For the KTM 890 Adventure and Honda Africa Twin which mainly use Torx, I add a T25, T30, T40 set. Also pack a 100 mm extension and universal joint to reach fairing screws.
The puncture kit deserves its own budget. A standard kit with plugs and glue (Stop & Go brand or similar, €35) weighs 400 g and fits in a pannier. I always add:
- 3 × 16 g CO2 cartridges with threaded adapter
- 12V mini-compressor like Airman ResQ Pro (450 g, €90, 25 L/min output)
- Reinforced plastic tyre levers (2 units)
- Self-adhesive patches for inner tubes
"Over 12,000 km in North Africa, I had four punctures. Three repairs with plugs, one inner tube for a sidewall tear. The compressor got me out of trouble every time."
Spare parts to pack depending on the bike: folding lever kit (Moroccan tracks, they break), DID or Regina chain link in the right size, 10A and 15A fuses (minimum 3 of each), 2 × H4 or H7 bulbs depending on equipment. On modern full LED trail bikes like the Ténéré 700, forget the bulbs.
Emergency repair materials: the MacGyver essentials
Gaffer tape deserves its reputation. A 10 m × 50 mm roll fixes cracked plastics, holds an electrical cable, temporarily secures a mirror. I always take professional 3M (€8 per 50 m), Chinese versions don't handle engine heat.
Quick repair kit:
| Material | Main use | Weight | Price |
|---|---|---|---|
| 3M gaffer 10m | Fixing, sealing | 200g | €8 |
| 200-300mm cable ties | Exhaust, fairing | 50g | €5 |
| 2mm annealed wire | Robust fixing | 100g | €3 |
| 10-16mm stainless hose clips | Hoses | 30g | €6 |
| Two-part epoxy putty | Crankcase repair | 100g | €12 |
300 mm cable ties hold a split exhaust or detached engine guard. I count 15 minimum, including 5 extra-wide for luggage attachment. Annealed wire serves for structural repairs: luggage rack attachment, bent sidestand reinforcement.
Epoxy putty like Pattex Repair Express saves cracked crankcases. Instructions: degrease with petrol, sand with sandpaper (80 grit), apply 3 mm minimum layer of putty, leave to cure 24 hours. It'll hold enough to get home, not for 5000 km.
Another essential: 5 metres of 1.5 mm² multi-strand electrical cable and 10 crimp terminals. Vibration kills electrical connections, especially on KTMs which have a well-deserved reputation in this area. A compact wire stripper completes the kit (50 g).
The spare inner tube is questionable. On tubeless tyres like the Continental TKC 70 fitted as standard on many trail bikes, it's a lifesaver for major tears. But it weighs 800 g for a 150/70-17 rear wheel and takes up space. I only take it for routes with more than 30% remote track.
Electrics and communication: staying connected without excess weight
The original battery on modern trail bikes struggles with continuous USB accessories. A dual USB socket mounted on the handlebars (RAM Mounts model at €45) wired directly to the battery via a 5A fuse solves the problem. Average consumption: 2.5 A to charge a phone and GPS simultaneously.
The compact 65 W mains charger with USB-C and USB-A ports (Anker Nano, €70, 130 g) charges phone, power bank and GPS in 2 hours. Campsites and hotels all have 220V sockets, might as well use them.
For wild camping autonomy, a 20,000 mAh power bank (Anker PowerCore brand, 360 g, €50) provides 4 full smartphone charges. It also keeps the Garmin Montana 700 or TomTom Rider GPS powered for 15 continuous hours.
Lighting and electrical safety:
- 400 lumen LED headlamp (Petzl Actik Core, 75 g, €45)
- Spare USB-C and micro-USB cables (50 cm each)
- 12V cigarette lighter to USB adapter (10 g)
- 5 m electrical insulating tape
- 12V pen voltage tester (20 g)
The headlamp is used for night repairs, pitching the tent, or finding something at the bottom of a bag. 400 lumens is plenty, 1000 lumen models are marketing. The 50-hour runtime in economy mode covers a week without recharging.
The voltage tester avoids searching for an electrical fault for 2 hours. Battery at 12.4V when stopped: OK. Below 12V: it's dead or a parasitic drain is emptying the charge. Simple and effective.
