To do or not to do, and why:
1. Complete the hard break in process, for 50~60km.
2. After that, for the remaining 1000km, it is actually ok to load the engine at low speed, examples:
- pull full throttle at every gear, but do not exceed certain RPM. I'd say some where 6000 RPM is safe. similar to hard break in, just continue it to 1000km. The pantang here is high RPM.
- pillion rider, again, at low RPM only.
- go downhill with engine braking, but watch the RPM...
- reason for above is obvious, you can load the engine, but do not let the RPM go too high.
3. An online article I read last time said, the engine continue to 'shape' even into 20,000 miles, that is if we continue to use mineral oil, which is a good thing. If you choose to use synthetic oil too early in the engine life, it will start to glaze, which is bad.

Is it Honda Wave? Wave is a simple bike. In fact, it is a powerful 100cc engine. I like it better than Lagenda. Not sure about other models. If a Wave also cannot maintain for 10 years (counting from manufactured date), then LC will be more difficult, for the same reason it is liquid cooled, it can be less reliable than air cooled engine. Some extra problems dealing with liquid cooled engine is water leak into engine, or engine oil. Some cannot be fixed until the whole engine is rebuilt.

Suggest you figure out what's wrong with the Wave and quantify the cost to fix it. Otherwise, if you keep the same mentality with your LC bike, it will probably last you 3~5 years before it start to give you problem. One thing to note, fixing a Wave is cheaper than fixing an LC. Try and go ask for price of parts, from major ones like engine block, head, valve, cam shaft, crankshaft and etc... down to minor parts like clutch plate, brake shoe/pads etc...

A bike in good condition can travel long distance, be it air or liquid cooled. I own three 2-stroke bikes, air and liquid cooled, manufactured in 1994, 1998 and 2006. All of them has experienced day trips of 700km+ distance.
