About this app

Bike Maintenance Lab is now MotoWrench! Same app, new name.

Your DR650 or XR650L has a 300-page service manual. MotoWrench makes it searchable — and tracks every service so nothing gets missed.

Need a torque spec? Valve clearance for intake vs. exhaust? The right oil filter part number? Ask in plain English. The AI searches factory service data, torque tables, parts references, and DRriders community knowledge, then returns a sourced answer in seconds.

Enter your odometer and get a personalized maintenance schedule with 70+ tasks, from oil changes and valve adjustments to chain tension and brake fluid. Everything is color-coded by urgency — overdue, due soon, on track — so you know where to focus.

Full reference library included: PDF exploded views, wiring diagrams, lubrication points, carburetor data, and step-by-step procedures from the manufacturer.

- AI powered service manual and Drriders forum search

Ratings and reviews

Invaluable app! I can tell the developer really cares for his bikes and this app shows it. Must have for when doing your own services and even if just to track when you last sent it for one. My only gripe is that it isn't linked to your email with a user name and password or something so you can keep the info in the cloud. I changed phones and had to re add my bike - maybe something to look at in the future? Even importing your data after exporting could be a game changer!

This app is amazingly well-done! I love how the information is tracked and displayed for all manual/maintenance items. My one minor complaint is that there seems to be a bug where it's showing me KM in some cases but I have MI as my preferred unit.

I haven't used it much yet I only just out my bike and odo reading in. I love how it gives you all the necessary services for every part of the bike and at what km or time they need to be done. And it's got the entire service manual in pdf on the app! So handy!

What’s new

Smarter AI!
- AI multi-turn conversation
- Ask about "fouled spark plugs" → get the causes AND a gentle reminder your service is overdue. No judgement.
- "Bike won't start" now triggers actual diagnostic logic — ignition coil, starter fuses, the works. Think of it as a mechanic therapist.
- Answers are grounded to the official manual and specs. Ask for oil plug torque and get the real number, not some hallucinated 100Nm that ends with you replacing the oil pan.
