Here's why:
* Model Variations: Yamaha produced numerous models with "RT 180" in their name over the years. There might be subtle differences in the engine that affect oil capacity.
* Information Availability: Finding specific technical details for a motorcycle from 1986 can be difficult. Older models might not have the same level of online resources as newer ones.
How to Find the Information:
1. Consult the Owner's Manual: This is the best source for information on your specific motorcycle. If you don't have the manual, try to find one online or through a Yamaha dealer.
2. Check Yamaha's Website: Look for a section on older models or their archives.
3. Contact a Yamaha Dealer: They may have access to technical information or can refer you to a specialist.
4. Online Motorcycle Forums: Search for forums dedicated to Yamaha motorcycles. Someone may have experience with the same model and can offer insight.
General Safety Tip: When working on your motorcycle, it's always essential to consult reliable sources for accurate information to ensure proper maintenance and safety.
