Different bikes for different purposes.
Let's face it, you simply are interested in the best performance for your buck. If that's what you want then there is no better class of bike for the latest tech and pest performance than the liter race rep segment. Does this mean that all other types of bikes follow suit?
No. Sometimes you just want to get on a bike, tool around in the countryside with no pretentions or ego driven feelings, smelling the roses, so to speak. Riding for the sake of riding. Simple and pure. That's what cruisers and sport classics are for and why so many manufacturers still have them in their lineup. No need for 200 RWHP and all kinds of electronic gimmeckery and top shelf componentry for this kind of riding. Is it wrong that people like this kind of riding?
Judging by the way you post on this site, you obviously like hanging out at the local coffee shop or other shit hole where you believe that's the place to be, talking smack about each other's stretched swingarms and 240 wide rear tires, chrome heelguards and such. Some riders like to get out and ride and not care what others think. No do they need to hang out in groups trying to impress each other.
As for Jap crap, I'm not sure why you're taking such offense if you're not Japanese. Besides, even Jap crap has much of their parts coming from China and Indonesia. But I have to admit, it kind of is crap. I've had a Ninja 1000 for almost a year now and it's going up for sale. The most boring bike I've ever ridden. Decent enough, but the I-4 bores me to tears. Cracked swingarm and leaking head gasket and an electronic glitch that shuts down the engine while leaned over or while braking hard. I just bought an underpowered archaeic Guzzi and have more fun on it. Fun, that's what it's all about, isn't it? Who cares what bike you have your fun on?
But I do have an HD in the garage too. It's actually been sitting in the corner of the garage for 10 years, untouched. I enjoyed it for a bit. And will again someday. Lots of othe bikes for other reasons have happened in the interim. All my favorites have been the air cooled twins, I must say... all 3 brands of them. All have been reliable and cheap to own over the years. The 4 cylinder ones have been my least favorite and most expensive to keep running. But I'm still glad they exist.
