$7500 OTD. what are these people smoking?

Juanro 03-27-2017 02:10 PM

Well, they can then swap the cranckshaft & gearbox, fore & aft... taking weight close to the CoG, and clearing space in the front to route the header pipe out of the way... ?
Can't remember any motorcycle engine built that way.

Most if not all longitudinal V engines have the rear cylinder exhaust "backwards" and seems to work fine right?

They do have some heat issues. If you get a chance to ride a Panigale, make sure you're either going fairly fast, or have thick underwear :hehe:

I know HD have had some battles with this, too.

It's a lot of money, isn't it? The common OTD price for the 300 was around 6k, which is also expensive. People pay it, though.

Yep. The twin cam would eat cam shoes from running too hot. They ended up trying to sell you the gear drive option before it left the showroom floor. Harley's run dang hot, not sure about the new M8 though. Haven't looked. My buddy bought a trike and just opted for the gear drive before he brought it home. Three other friends ate cam shoes, which bits got pulled right into the oil pump, etc..etc... Luckily, it was warrantied no problem.

Don't you think that this is because it makes so much sense to have the intake for both cylinders inside the "V" where you can have a common air box? Otherwise you end up with a very hot exhaust next to the intake from the front cylinder and the rear cylinder intake scrunched between the suspension bits and the rear airbox who knows where.

The Harley XR750 flat tracker was like that. "Henderson head" they called it. Both cylinders had it's own carb as opposed to the street bikes that shared a carb.

It's good to see some activity in the RX3 section of the forum but......

Just in case anyone forgot this thread is about the RX3 and the X-300: :)

I took another test ride today. This time a 20 mile ride on a non-ABS version:

Go back and talk directly to the owner/manager. Have him ride your CSC along with you on the Kaw for at least an hour. Video his reaction after the ride & price point discussion.:lmao:

FWIW, I think that a 300cc twin would have some real advantages over a 250cc single. 50cc more displacement, more horsepower and twin cylinders so less vibration. On the other hand, a thumper usually has more low end torque and is a simpler machine. I respect anyone who decides he wants the more complex bike. Maybe he needs that extra high end horsepower. I'll stick with my relatively simple 250cc thumper. Oh, and I will still curse the chore of adjusting those exhaust valves.

I think jb has got a crush on a green machine :D

You can't take it with ya when you go.

BB......they come in silver and gray, too... ;)

I really like riding the RX3......or I wouldn't have ridden 11,000+ miles in a little over a year....more than my other 3 bikes combined.

OTOH, my maintenance issues with the RX3 have not been much fun. Hopefully my experience is not typical.

No one else seems to be posting with the same issues as I have.

And, Jay, it may not be fashionable on ChinaRiders, but it isn't always about the $$$.


Back to the bikes:

The X-300 has a really high revving engine....like a sport bike...and I thought the RX3 was high revving.

I was up to 6th gear at about 45-50 mph.

At 60 mph at 7,000 rpm, I was reaching for a non existent 7th gear, and going faster made the engine feel buzzy, and like it was really "screamin'.

It wasn't a feeling I was used to, and don't know if I like.

For me, the RX3 is happiest from 5,000 to 8,000 rpm. I generally find myself cruising from 5,500 to 6,500 rpm.

If I maintain 7,000 to 8,000 rpm on the RX3, my gas mileage drops by ~10 mpg (US gal).

It may be that I am more used to the vibrations of the RX3's thumper, but they seem more pleasant (in tune with my "chi"), than the higher frequency vibrations of the X-300's twin.

:hmm:

I realy don't think our market is big enough for it's own special model...
