What engine in the Scooter world is Not OHC with Ball Bearing Crank Journals in the last like forever? Boy I better stay away from that Flat Head Push Rod Babbit Journal Crank Bearing Scooter or M/C Motor.. c'mon i have no idea why you think that's so funny. it's a fact that OHC engines can sustain a higher RPM than ones operated by pushrods. ball bearings present less friction than a bushing. i apologize that i haven't tore down every scooter engine on the planet.

Its the Scooter world. I find allot of humor starting with my own GY based rolling pile of Plastic. Why so funny? cuz is a simple no brainer, really nothing else out there. we prolly go back to ww1 or ww2 to find some Push Rod Scooters. I'm sure someone will find something out there. And were could I dig up some ol Scoot engine with Babbbit bearings. HD still sticks to its legendary Push rod motor in there full size bikes. And yes there are OHC/OHV but there are Rocker Arm actuated, The Rocker arm Scoot is more like Low rpm general service tater digger engine. In the big pictures of two wheel machines these Scoots are all done when a real bike is just starting to come alive. You don't have to apologize for anything just laugh and roll with it.

And were could I dig up some ol Scoot engine with Babbbit bearings. that's the thing, people like me don't know that. all i've ever known was american automobile engines, and more specifically my dads 289 ford and 327 chevy engines. every book i've ever seen says car engines use babbit crank journal bearings, and push rods. it wasn't until later that i found engines with overhead cams, where the cam operated the valves directly ( no rocker arms.) what's more, the above engine had 2 cams, one for the intake valves, one for the exhaust, (it was a 4 cylinder fiat engine, apparently made in italy) but it still used babbit crank bearings. if i'm not mistaken, i believe the specs for the above engine said it could easily sustain 10,000 RPM. so naturally i'm going to assume all engines use babbit journals, until i find out differently. well, okay. how's that?

Harley sticks to the old pushrod engines,their mechanics have to have something to do, every person I know who has a harley has it in the shop more then on the road.

engines with pushrods are good engines, but they can't handle rpms much higher than about 8000. i would imagine that most shop repairs are caused by the rider over taxing the engine. (other than warranty service)
this probably explains why most chinese engines just don't simply blow up. they are better equipped to deal with high rmps AND most have rev limiters.
a 250cc is the minimum stock scooter i would take on the interstate. i only rode mine short distances on state roads approximately 20 miles or so, some longer some shorter. the majority of my miles was on county roads. i would be hesitant to take a small wheeled scooter on the interstate. i've hit bumps in my car that would probably wreck a bike.

I have done a long haul on a 150cc from PHX to Kingman. It was not the best experience. I have also done a long haul with two up on a 250cc. That was a better trip

It was a pawned item and the owner ended up in jail. The pawn shop owner was selling it for 1k but he just wants it gone so he is gonna give it to me for 700. It needs a new battery but other than that it looks good. Superjew78, Just saw this post... Have a bone! You MUST have one of the best "handles" on the site! Most of my Jewish friends are pretty super... Anyway, I've been riding now for over 50 years (mostly big bikes, with a smattering of 250-300's over the years) so I have considerable experience. I'm now 70, and arthritis keeps me off the big bikes and I've gone to step-through scoots. My current ride is a well-used Kymco Grandvista 250. It is a short-wheelbase scoot with small 12" wheels. (roughly Chinese 150 size, and 360 pounds). It tops out a little over 75-mph on LEVEL road without headwind. However, realistic cruising speed (including hills and wind) is 65, or 70-mph tops. "Minnie Mouse" as I call her will cruise 65 all day long. The short wheelbase and small wheels are no problem, including handling blasts from passing trucks. Unfortunately around here, freeway traffic often runs well over 80-mph so EXTREME care and watching the rearview mirrors is a "necessary evil"... LOL! IF your trips can be SAFELY negotiated at 65-70 you should be OK. A 250 SHOULD be fine if drivers would make even a little effort to keep within 10-mph of the speed limits. Some places they do, here they don't... LOL! I still ride the freeways whenever necessary, I just watch VERY carefully for the bozo coming up on my six at ninety. That bike in your post looks GREAT! Apparently a "twist-n'-go 250 motorcycle". Easy scooter controls with full-size cycle wheels and cosmetics. I'd say that's the best of both worlds. The large wheels ARE superior to small scooter wheels at high speed, and rough roads. The secret to small wheels at speed is to be sure to have P-rated tires, perfectly balanced... Mine actually ride and handle as well or better than my old Harley baggers did "back in the day"...Experimenting with roller weights (or better yet, sliders) can add a little more speed, acceleration and gas mileage. And can be done with simple tools with little mechanical skills. Something to try. I equipped my scoot with the largest trunk, or "top-box" I could find from eBay... It holds 2 full-face helmets or a LOT of groceries from Wally World... I also added "throw-over" saddlebags, again off eBay for times when I need even more storage. Your motorcycle-style scoot would look fine with trunk, and/or saddlebags. With no flat floor to carry stuff on, you'll need some storage for errands. Below are pix of the mouse... If a small scoot can function with trunk and bags like this, your cycle-style ride certainly can do even better... and that trunk is HUGE... "Harley-sized"... LOL!If your pawnshop prize doesn't need more than a battery, for $700 you will be a happy camper! A 250 can be used on the freeway, ESPECIALLY if 65-mph will be fast enough to be safe. And, in town, it will be PLENTY fast for frisky traffic... I've now had my 250 for 3 seasons and am very happy with it. Ride safe!Leo in Texas

I've got a lead on a Rukus 250 which are great bikes, which is capable of running on the highways, but I would prefer to keep to backroads anyway, you lose so much of the enjoyment of riding when you are battling high speed traffic on a boring interstate, it's like being behind the lead dog, the view never changes

I really don't understand why they hold their resale so well compared to the Reflex. Hope you can get a good deal on it. You will love it, I am sure. As far as highway driving is concerned, I also don't use limited access highways on my scooter. I agree with you, it's not because it's not capable, with the variator mods my Reflex will do 80, its just that if I was on a freeway, I might as well be in a car. Most of the time, surface roads will add only a few minutes to your trip, but they will also add a lot of experiences that you will just drive by on the freeway. BTW, I had that same opinion when I rode my liter sport bike as well. The reason I own a scooter is because I love to ride it, why cut it short by taking the fastest route to your destination?
