Quick note...
My new tire is in, and incredibly it has RAINED for a week, and more rain predicted for the NEXT WEEK!
It NEVER rains here in August... Cheesh!
The new tire is fresh, less than a year old. I'm anxious to get it on. Also, today I carefully re-checked the entire old tire. That 1999 must be the manufacturing date. It's the only changeable number on the tire, not in the permanent molding of the sidewall.
Also, I thought Shinko tires were made in China. Probably some are, but THIS one is proudly, prominently marked in the permanent sidewall mold "MADE IN KOREA"... As if NORTH KOREA doesn't even exist... That is cool.
I'll keep posting if the monsoon ever stops...

Most Shinkos are Korean...mine is. I recall the IRC on my wife's Pacific Coast was made in Indonesia.

Shinko is now owned by Yolkahoma.... Just a little side note.... BTW, I have a set of Mezlers I love on my 1100. Couldn't believe the handling improvements over the old Dunlops that were on that bike. On the 1500 I run Shinko's. On the 1500 they are fine and better then the dunlops that I took off.
On the 1500's, some guys run car tires. I might try that when I wear out the shinko. The 1500 is a very heavy bike with lots of torque so they tend to go thru rear tires. But the same rules apply, check them tires often (if not every ride); when I commute, I check once a week, if I am not commuting on the bike, then every trip.

No, Shinko is owned by Shinko...tbey bought Yokohama's motorcycle tire operations.

Got the new front Shinko...Well, I tried to sneak between rain-storms and almost succeeded...  I got to my dealer and he installed and balanced my new (actually NEW 2015 fresh this time) Shinko. Juan, the head service tech did the job as fast as humanly possible and I was on my way home (only five miles).
I made it half-way home before the sky opened up monsoon-style... So... Now I have TWO good reports to post!
First, the new Shinko has great manners on rain-soaked, oil-slicked tarmac. I truly HATE riding in rain, but no choice. My Michelin Power Pure rear tire which handles like a dream on dry road, IS a tad "slippery" on rain and oil, as any tire usually is. But, the Michelin has a sort of "grooved-slick tread which hydroplanes easily. On the other hand, the new Shinko with its old-school, block and groove street-tread gripped the slippery road much better. Chalk one up for the Shinko... But on dry stuff, the Michelin is a little better.
Second, the aftermarket GIVI windshield is fantastic. With all the scooter plastic below, and the big windshield above, so long as I could maintain 30-mph I stayed completely dry! I only got wet at the one red-light I caught. Two good reports all from one short ride... Pretty sweet!  I hope I'll have no other noteworthy "events" to report on the new tire... LOL! Ride safe,Leo (doing my sun-dance for dry weather) in Texas

The Power Pure design is great for preventing head shake on the front wheel but this ability to prevent head shake also reduces its ability to handle wet roads. On the Shinko you may need to be careful with your tire pressures so the tread blocks do not feather due to squirm during hard braking which can become an issue with a big guy on a comparatively small bike. Sometimes just upping the front tires pressure 1 or 2 psi over whats on the tire placard mounted on the bike can help prevent this mind you as long as you do not exceed the MAX psi stamped on the tires side wall.

Tires in general are all the same as far as I'm concerned. ... Tires might all come from China now, but they are NOT all the same. I got a set of Tigerpaws for a car (thankfully NOT my Taurie-love!). I was working a minimum pay job and paying off my first knee surgery, so had little spare money. I got all four installed for under $100. Good deal, right? Wrong. They had total crap traction. Just doing regular turns at intersections would result in squeal and slight sliding. And no, I am so NOT a turn-demon! I ended up losing that car 'cause I topped a hill and saw a car ahead with its backup lights on, stomped on the brakes and skidded, immediately starting pumping the brakes instead but the crap-tires never attempted to regain traction. Slid off the road, hit the ditch, and flipped the car. I will NEVER NEVER EVER skimp on tires ever again! Now crawford, imagine putting the 2-wheeled equivalent of those Tigerpaws on your scooter. Make your stomach squeam a little, doesn't it. >'Kat Uniroyal Tigerpaws? I have a set of those on my 2007 Mercury Milan - and I have found them to be excellent...  |

You are RIGHT! I love that Michelin (never tried it in rain before) and with so much "slick" tread with rain-grooves, it's a joy on pavement, and I expected it to be a tad squirrely on rainy/oily pavement. OOOHHH... Stay OUTTA that greezy CENTER of the lane!It WAS sorta fun though to be able to absolutely SMOKE (or should I say "steam") the Power Pure with a frisky twist of the mouse's ear... LOL! I used to ride bikes that could do THAT on DRY pavement... sigh...
The Shinko does indeed perform and wear much better when FULLY inflated. It's rated at 40 PSI max, but on "Minnie" it seems happiest at 36-38 pounds. Less than 36 pounds and it gets "soft" and a little shaky. Tracks swell with no shake when good and hard.I must admit I'm a sucker for that old-school block and groove street-tread too. It just fits the look of an outdated ride... It's SO fifties "Vespa-esque"...Looks good under my lite-up-goose! The Michelin is a great tire but looks too "modern" on the old girl... Since this Shinko is "fresh" and hopefully not near its "decomposition" stage, I'm looking forward to several good riding seasons... Ride safe... and enjoy steaming that rear meat on a rainy day!Leo |

I am running a Harley style Dunlop on the back and the Power Pure up front. Liked the more heavily chevroned tread patterns in the wet but when your a big body and a bit ham fisted on the brakes those chevrons tend to lean back and feather on the front edge while braking which changes the dynamics of the contact patch and leads to head shake even when not braking making tuning in the correct tire pressure on that style tire very important.
You won't really notice it for a few thousand miles and if you don't adjust the pressure quickly the wear can become deep enough set that you'll have to live with it or replace the tire.
Many go looking for rim, brake, fork of frame issues when its mostly just the result of running the front tire pressure a few psi too low for too long.

You said it, brother! Have a bone! Tire style and pressure make a WORLD of difference.My old Chinese 150 wore factory Kenda J-rated OEM cheapies and they were fine for six years. Not one complaint... Even then, there was no dry-rot or handling issues. But if they got below 34 pounds pressure, wobble developed. And of course, the old 150 wouldn't run faster than 55...
My Kymco had brand-new Kenda J-rated tires on her when delivered. Most folks think the J- speed rating is OK for 99% of riding. WRONG...
If I ever end up on another 150, I'd still fork over the few extra bucks for quality P-rated tires, well-balanced on it... The increase in ride and handling is worth it!With the J-rated Kendas, The Kymco's handling was SO bad, I almost tried to take the scoot back. Shake, high-speed wobble above 65 which is already over the 62-mph rating (and FORGET about going 75... LOL!) and an irritating "thumping" (like out-of-round) as I slowed down to around 20-mph. After installing the Michelin on the rear and the Shinko on the front (both 92-mph P-rated) all handling issues were gone... AMAZING the difference tires make! Of course, proper BALANCING is also a must, ESPECIALLY on small 12" rims. The old Kymco will now run smooth as a field-mouse backing into a pussy-willow from walking speed to  + downhill! Tires are a biggie on any bike, but I believe on SCOOTERS with smaller wheels they are even MORE critical to safety, AND to general riding pleasure. You are absolutely right about checking your TIRES before looking into frame, fork and suspension gremlins. They MIGHT exist, but check those tires first...Ride safe!Leo |

When slowing down is where the shaking more often shows when its due to low pressure front tire wear especially if the pattern is made up of staggered left and right Chevrons. It can actually set up a harmonic that can catch one unaware of this possibility off guard and jerk the bars right out of your hands. Not a good time to grab a handful of brake.
The old school highway ribbed front tires to me had a certain advantage in preventing this as this seems to be more common with the new computer designed tread patterns unless you go with the semi-slicks. Sometimes when this happens the cure is to simply lay off the brake and give the bike a little throttle to get above the harmonic speed that is causing the wobble and then slow down again.
Its best to vet out tire choices and understand what tradeoffs you are making when you choose a particular tread pattern and tire rating so you can lessen your changes of experiencing head shake.
The cost of decent fresh tires today especially in the smaller sizes is not that high with the price difference for many being what they would spend for lunch at a Burger chain. I know I would rather brown bag my lunch for two days and spend that coin on the better tires. We are all worth more than a couple of Big Macs or Whoppers.
All part of riding safe.
