I saw one at my dealer this weekend. Caspian Blue. Very nice. The only thing I was puzzled by was the weird nylon-like seat cover. I didn't think it was bad, just weird. The exhaust nozzles don't look quite as cool in person when you realize they're just three short pipes that stick out of a box, but they're still neat.



I'm trying to get my friend to ditch his V-Rod and buy one.

The lubrication superiority of synthetic oil is getting overblown. Apparently the oil refineries are making nearly the same stuff. Imagine what it costs to make different kinds of oil. They won't tell you that synthetic isn't any better than the regular petroleum oil, because they make more money selling synthetic. Toyota recommends the cheap $1.30 a quart oil in their cars.



What is more important is the viscosity and to some extent the additive packages. It turns out synthetic oil is slightly less viscous for the same viscosity rating, because it is a better lubricant and slips better. I tried running 20w50 synthetic in my Harley and started getting a little lifter noise. When I switched back to regular 20W50 the noise went away.



I also read an article from Kevin Cameron who said that the additive packages are overated for motorcycles, at least until the rpm reaches about 19,000 rpm. That explains why oil labeled for cars works OK for motorcycles. But, if you run at redline a lot maybe you should use motorcycle oil. However, Motorcycle Consumer News tested a lot of car and motorcycle oils and found no difference between them.



I've run Mobil1 15W50 car oil in my Triumph Speed 4 with no problems for the last 10,000 miles. It's cheaper than Triumphs' Mobil1 15W50, which I believe is exactly the same as the car oil.



Use the correct viscosity and change the oil frquently (2000 to 3000 miles). Gear boxes chew up engine oil fast. I noticed a change in engine vibration about 300 miles after an oil change in my old Yamaha Virago 750.

Gearboxes can be hard on oil. With unit engines you may want to change oil more often.

102K on an NT650. Started out using Mobil1 15w50 later switched to Amsoil 10W40, which seems to hold up better (based on shifting feel) than the Mobil1. Oil changed once a year 5-8K miles. Bike still runs great, never been apart, no clutch slip. I would not hesitate putting it in an older motor as long as its had regular oil changes.

As an experiment I used Mobil 1 in my 1989 Pontiac Grand Am. I kept in in for exactly 100,000 Km (Approx 60,000 Miles I think). I changed the filter every 5000 Km and only had to top up with Mobil 1 at that time. That Quad 4 went for approx 350,000 km and was still running fine and not using oil, when a drunk turned left in front of me at an intersection. Try that with regular oil. I just did the the first oil change on my VFR and used Honda Oil and a Honda Filter. Why are Oil and filters from bike shops so expensive?

Yes they can be harder on it. But from what I remember about the lubricant business, the frequent oil change thing is a good part hype. They're in business to sell you more oil and filters. Notice that the vehicle manufacturers recommend oil changes far less frequently than the oil manufacturers push. The oils are actually far better than the oil people want you to know. When was the last time you had an oil related problem or a significant loss of performance that can be traced back to insufficient lubrication? Well, being that you change your oil so frequently, you probably haven't had any. How about someone you know?



I've never had a problem with a car or motorcycle because I didn't change the oil every 2000-3000 miles. I stopped doing it when I started working for the oil manufacturer and was told to stop wasting my money. Now I usually change the oil about every 4,000-5000 miles. Andm especially with synthetics, that's not even necessary. It's just an ingrained behavior.



The API (American Petroleum Institute) mandates a certain additive package to get the current year's approval (and the standards keep getting higher every year). That means all conventional oils with current API approval are virtually identical. In fact, as you mentioned above, many of them are the same oil rebranded. The synthetics and semis may differ a bit more, but they're all basically very effective. They just get there a little differently.



Of course, it can't hurt to change the oil more frequently. And if you want an extra safety margin and don't mind spending a few bucks, that's fine, too.

Because they say Honda on them.



(or insert any bike makers name in place of Honda)

The synthetics do differ more in formulation, but they all basically work about the same. Conventional oils are all virtually identical. The API mandates the additive package for the current year's approval, so, naturally, the resulting oils are the same.
