Got a pair of Shinkos 712 and replaced both tires and tubes. Curious how long will they last but they were half the price of BT45s.

Not surprised by the price differential. Shinkos, unlike BT45s are not quality tires. Sorry.

+1. Reports are they are a hard compound tire, you should get a lot of miles at the sacrifice of grip. I really like the BT45's on my K4.

They are continuing od Yokohama tires. So far they seem good, i need some longer mileage tires.  Dorothy takes two rears and one front BT45s a year  - due to my fat arse and the miles I put on her.
Frankly, how often you need super gripping tires for commuting and local roades?

I heli-coiled the crap out of my front brake brackets.  From the total of 6 (4xM6 and 2xM8) there was only one M8 that did not need fixing.  The rest would hold but not tighten tight enough for the peace of mind.

I spent the money and got me a set of main metric  - for my ham fisted wrenching on aluminum parts it will sure come handy.

Well far be it for me to disagree with the collective genius of my learned colleagues, but recently I've heard good things about Shinko tires, so I did a little research and found some positive reviews of the Shinko 712's:

Reviews by Source

www.motorcycle-superstore.com Front

41 reviews. 4.6 of 5 stars. One rider reports the tire rides great, handles great, balanced great. On a 1987 Super Magna – tires riding smoother than previous Metzeler and Dunlops, great for the price. On a 1980 Suzuki GS750ET – took a 12 day, 6,300 mile road trip, loaded heavily, rain, sleet, mud, heat and never slipped once, rear has maybe 500 miles left. Another says the tire has outlased Dunlop at less than 1/2 the price. On a 1974 Suzuki GT750 – difference over the Dunlops was astounding, had real confidence going through the corners. Another reports that the tires follow road grooves. Another had the front start to peal away from the tire, Shinko was great in replacing.

www.motorcycle-superstore.com Rear

96 reviews. 4.4 of 5 stars. On a custom Sportster – rate the tire better than Dunlop, hold the road in both wet and dry. On a Suzuki RE5 – handling improved 90%, balancing was easy. On a 650cc twin – great value for the price, third one on the bike. Another says this is the fourth set of Shinkos, rider very aggressively in the twisties, stick to the road like glue, get around 7,000 miles from the rear. On a DLA650A commuter bike – 15,000 miles. Another got 3,500 miles on the Shinko 712 as compared to 5,500 on a Dunlop K591 at 1/3 the price recommend the Shinko. A couple of people reported having trouble balancing the tire.

www.bikebandit.com

108 reviews. 4.7 of 5 stars. On a Yamaha Seca – grips well, performs in the wet, did need to use a good amount of weights to balance. On a Yamaha 650 Vstar and BMW K100 RT – grip the road surface extremely well, easy to install. On a BMW K100RT – tire handles very good in all road conditions, even dirt mountain roads. On a GN400 – make the bike fun to ride again, can lean hard into corners and not lose grip, amazing quality for the price. Another says not the greatest tire for hard core riders, but for people who like to take easy rides it is a great tire. On a K100RT – better than Metzelers, more stable, corners and sticks like glue.

I need some new tires for my mighty black 'Wang, and I can get some rather attractive Stinko white wall's for cheap, so I think that I might ignore the howling of the tire snobs, and pick some up, they've gotta be better than my 20 year old Dunlops! ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Yes, Terry, that's where I collected my wisdom too  :)

Also Amazon has positive reviews, 4.5 stars or so. 

I figured for the cost and for the rest of the season they are great.  The plan is to get K3F finally on the road and Dorothy needs 2nd gear fixing plus other things, she will be off the road for some time.

There is one thing I experienced already.  It is either going from center flat rear to a new tire or maybe Shinkos are rounder in profile, but while cornering I would experience this too-easy-to-feel-comfy lean over, expecting more resistance to lean the rear wheel and instead it just goes smooth as butter.  Hard to explain the butt feeling here, hope you get it  ;D

Yeah mate, I know what you're talking about, whenever I get new tires on a bike it suddenly feels like it want to go around corners again, the tires go from good to bad with such subtlety that you don't realise how bad they are until you fit new ones.

I'm really looking forward to putting new rubber on both my 'Wang, my FJ1200 and my 750, hopefully the tax man will be kind to me this week. Cheers, Terry. ;D

I know that feeling too, and like it. 

 My RD350 needs some new rubber and I just might order some IRC 'cause I like the vintage tread pattern. The reviews arent the best, oh well, it aint my "go fast" bike!

That RD is a little rocket Steve, and they were great handlers in their day. If you can stretch your budget, get some Pirelli Sport Demons for it, and you'll be undercutting R1's! ;D

Frankly, how often you need super gripping tires for commuting and local roades?

Every time I ride, actually. Why would I not want superior traction in all conditions, on every mile. It's the only part of the bike in contact with the road surface. Safety first=proper traction. Unless you know of a different formula?

I have to agree. Given the minuscule contact patch from the tire to the road, I want every reasonable advantage. It's not only about cornering or acceleration but also braking.

I'm sure what was written was not what was meant, or didn't come out right. But, to contemplate running a tire that is "good enough" for most commute rides is akin to those people who carry a concealed firearm "only when they go somewhere that they might need it". My immediate response to them is: "Then why to there at all!?".

None of this is targeted at disparaging Shinkos. But your written logic bears some scrutiny, if you'll forgive my presumptions. There is no circumstance ever, that I can imagine, where the best possible equipment to provide a safe ride is my singular priority. And I hope it is yours as well.

Good riding!

I always buy the best tires i can , even at legal speeds you can still corner pretty hard  {roundabouts  ;D}, and it definitely helps braking in both wet and dry, good shocks are imperative as well, its a small insurance policy, why take the gamble on inferior tires {and suspension} if you don't have to or want to for that matter... ;)

Same here, not all I wrote was understood the way I meant it.  It is possible, that Shinkos are not the best tire out there, but I put tens of thousands of miles on Yokohamas in Europe and never had any problems, not even a flat tire, ever.

Shinkos work for me and I have 5000 or so more miles before the rear needs replacing - so far it looks like they have a good cost/performance ratio for my application.

I get what Terry is saying. For me, not being a spring chicken and not being able to afford missing work (and since these bikes do not generally handle or brake as well as modern bikes, I'll pay the extra for better tires to give me better traction. I want as much safety built into the equation as I reasonably can afford that's all.

Yep, I'm not disagreeing with anyone who says that good tires are cheap insurance mate, but I don't think Stinko's are that bad. I had new Metzlers on my first BMW R100RS and they were sh1t, at the same time I bought my first F2 which had a Stinko on the front and an old Dunlop on the back, and it was much more confidence inspiring than the BMW, which pissed me off........... ;D
