Synthetic doesn't guarantee longer intervals - especially with a small capacity like the CBR has - it should be changed frequently even with synthetic. We are only talking a small amount of oil and cost here - it's not significant. Use a good oil like Rotella T5 10W-30 blend and you are more than good - plus it's cheap. Synthetic oil can save your from engine damage at times where conventional oil would fail - so it's like cheap insurance.
87 octane is the right gas for a non-high compression engine - so it's not being "cheap".
I don't think a lot of people here only ride their 250 for a year or less, but if that's the case - why even bother changing the oil at all? I've changed the oil with synthetic even when I've been selling the bike. The cost is so minimal I don't sweat it.
If you plan to keep the cycle for a while it's just smart to run a synthetic oil, especially with a higher-revving engine and a small oil capacity.
Thanks for this information.
I have a 5 quart jug of conventional 10W 40 left over (from my old scooter that I sold) so will finish that up and then look into synthetic.
I dont have the owners manual handy but what does Honda recommend? Do they say synthetic? My bike is out of warranty (2 years old)
But I would ALWAYS follow the maintenance schedule even if selling the bike because that would be a form of dishonesty to do anything that would harm the bike and then sell it to another poor victim. Unless it was an expensive service such as "adjust the valves" or something like that in which case i would certainly advise the new buyer that the service had not yet been done and that they need to do it ASAP.
But i know there are bad guys out there who do not do the maintenance and then sell the bike to somebody. Thats why I am so wary of buying motorcycles with over 3000 miles on them because you "never know".
I myself plan to keep the bike for at least 3 to 5 years or more. I was looking for an inexpensive and reliable commuter bike and I dont see anything else that can top this Honda for the bang-buck.
In my use-case it would be a "downgrade" for me to switch to a 500cc because it would be less fuel-economy and more expensive parts and insurance premiums. But I did get a chuckle today as I read a thread on this forum named "I keep getting bullied to upgrade from the 250cc"
Ha Ha! Someone said that to me the other day "Why do you ride that little 300?" and I said "Because I like it". I used to go into a 5 minute dissertation about its excellent fuel economy, nimbleness, light weight and so forth but now I just say "Because I like it". And then if they ask a specific question I will address only that point. Im not "on trial in a courtroom" to defend my choice of buying a 300cc bike.
Especially to some b!tch-boy that doesnt even have a motorcycle.
