That's a nice looking small bike. After some digging, I found that the MSRP is $4599.

The engine is a clone of the Honda XR400.

The way I understand it the engine is a downsized clone of the ill fated Honda GB-500. Like the SR-400 Yamaha in Japan 400cc engines are in a different class. It's built by Shineray in China.
I'm not really a fan of single cylinder road bikes and at that price I would look into the Benelli 302.

I'm not really a fan of single cylinder road bikes and at that price I would look into the Benelli 302. I must agree... It's a great-looking small bike, and probably is a good choice for general riding. However, I too am a tad shy of single-cylinder motors for cruising. I'd like a twin better... I keep thinking about my old Honda 305cc Super Hawk which I bought while at Fort Bragg, NC. That was probably THE best all around ride I ever had... It would suffice to do duty from anywhere from a bicycle to a long-distance, two-up tourer... Smooth, impeccable handling (for that time) and absolutely bullet-proof-reliable. There are SO few new bikes in the 300-500cc class nowadays, and so many are still single-cylinder models. It seems that the general market wants either a "moped" or a "crotch-rocket" and not much in between... All that being said, it's likely a good bike... Genuine products seem to be very good. My dealer sells a lot of Buddy scoots! |

Twins are easier to work on now, since the ECU takes care of ignition timing. Back in the day when we had to set dwell and breakers, I stuck with singles.

I might be oversimplifying it but my feeling is that two cylinders aren't working as hard as one. My four cylinder 750 hardly works at all. It just pulls and pulls.

W650 and I talked this little monster to death in 2015,,I could never get genuine co.to give me any definitive answers on availability or if it met carb compliance,,so I finally let the idea go,,,now it's finally here and carb compliant to boot ,,,contacted 2 local dealerships to see if they have one to sit on and am waiting to hear back,,as far as high speed work goes with counterbalanced engines they spin fine,,the only reason my dr350 isn't suitable for the freeway (it does 70-75 fine) the gearing is setup for the dirt and the engine is very busy ,,,with a final drive change it'd be just fine I just don't want to tear it apart every time I want to go on long distance rides,,,dating a girl that's shown interest in riding so I may get 2 so we can travel together,,,we'll see what transpires over the next few days ,,I could have had a ktm 390 duke but id much rather have a traditionally styled bike than a plastic wonder that looks like it came out of a Star Trek movie,,

I won't go into the crazy technical side but multiple pistons and crank throws share the load that a single piston carries. I can't gather any anecdotal evidence but I'm more inclined to believe that there are more high mileage twins than singles for whatever reason.

I can't gather any anecdotal evidence but I'm more inclined to believe that there are more high mileage twins than singles for whatever reason. There are things about a single "thumper" that I really like. However, my experience (50+ years) tells me that multi-cylinder engines just run smoother, longer and have a wider "sweet spot" for general performance.
One thing I do NOT understand is why in the sixties, V6 engines were tried, and FAILED miserably, being deemed "impossible" to balance. GM tried with V6's in the little Olds and Buick sedans and even resorted to using something like 150 pound flywheels to get them to run reasonably smooth, with NO success. They quickly faded into history. Grandpa wanted an inline six for grocery-getting and everybody else wanted a V8 for giddyup… and hang the gas mileage... LOL!
Then came the Japanese V6's, quickly embraced by Chrysler in their "K" cars. Wow! Smooth as glass. My '04 Honda Accord is THE smoothest running motor I have EVER owned... And it's a V6. Unless it's dead-silent you can't HEAR it running. Inside, you can't FEEL it running.
Just WHAT did the Japanese discover about the V6 that America couldn't figure out in the sixties?I'm amazed that Honda or some other Japanese bike maker hasn't introduced a sweet little 1 or 2 liter V6 bike motor! In short, yes, as an old-school geezer I love the sound and feel of a single, or V-twin. But for great riding, longevity and general performance I'll get modern and opt for a multi-cylinder mill!
Ride safe, and have a MERRY CHRISTMAS!Leo in Texas |

As a side note, W650. It looks like Kawasaki will bring the W800 to the States in 2019. Costs 10 grand though. That's about double my motorbike budget.

The answer to unbalanced V-6s is easy. Americans first hacked off the front two cylinders of a V-8 to make them. Primary balance of a V-8 is ninety degrees. Optimum balance for a V-6 is sixty degrees. Chrysler and the Japanese knew this and designed the piston bank offset accordingly.

Optimum balance for a V-6 is sixty degrees. Chrysler and the Japanese knew this and designed the piston bank offset accordingly. I know little about the offset, and have always wondered just how much it affects running... Some of the early car V8's appear to have differing offsets and seemed to run reasonably smooth. V-twin bikes seem to pop up with 45, 60, ninety-degree and various other offsets.. But then, NOBODY would like their CAR to run like the venerable Harley "Milwaukee Shaker'... LOL! Hog jockeys just get used to the bars being a buzzing blur at speed (sure keeps your self-winding watch wound) and idle speed shaking actually noticeably working the suspension...
Thanks for the info on the car V6's... It's something I've often wondered about. I'm overjoyed with the performance of my old Honda Accord motor... Just 3 liters (about 180 CID) and smoother than my old Cadillac V8's, instant throttle response and neck-snapping torque with obscene top speed... Hmmm... A "half-size" 1.5 liter clone would surely be sweet in a bike!
Have a wonderful Christmas!Leo |

I remember that the 60 deg v6s didnt require much balancing gear, but the  deg Buick v6s needed big balance shafts. -the v6 engines didnt last long in stock car racing either. The v6 cars could weigh much less than the v8s. However, the v6 cost much more to prep and operate and they suffered far more mechanical failures. -i still prefer an in line 6. Much easier to work on. |

I've had numerous old inline sixes... Usually the venerable Chevy "Stovebolt Six"... Had a '53 or '54 Corvette "Blue-Flame" six in my first car, a 1950 Chevy sedan. The original anemic 216 cid six with babbitt bearings and splash-oiling prompted GM to put a 4:11 rear end in the old girl just so she could move under her own power... Those short gears were SWEET with the "Vette six! The old gal was up to taking on the newfangled Chevy 265 OHV V8, and dusted off a few 283's when they became the rage... For drivability, I do love the old straight-sixes... I just never like the SOUND of 'em! Inline 4's don't exactly blow my dress up either, sounding like the Grinch giving us the raspberries... LOL! That old Blue-Flame Stovebolt had twin carbs, headers with dual exhausts, and ran like stink... But it still sounded like a Brit Jag, or Austin Healy... or a Good Humor ice-cream truck! Have a great Christmas!Leo |
