2017 Shinko 705 for the Versys

I'm a bit disappointed that my latest Continental Trail Attack2 set of tires hasn't lasted as long as previous sets. In fact I only got an estimated 10,000km off of this rear tire, and I had been expecting 15,000 to 17,000. Maybe they're using a different formulation?

Anyhow, I was reading JDRock's thread on advrider.ca and heard mention that the Shinko 705s were getting 6000 miles off of a rear tire, so I took a look at the price difference between the Contis and the Shinkos, and you can see the result.  

The post truck rolled up the driveway with my new Shinko 705s and I'm off to get them installed in Summerside just as soon as get finished this. Lol.

What sizes? The front is the standard 120/70R17 but Shinko doesn't offer the rear in the 160 width, so I went with the 170/60R17 as opposed to the narrower 150/60R17 offered as I know the 170 will slow down my turn ins and make the bike run a bit more stable in a straight line which is fine for some of the longer tours I like to do.

Shinko Canada sizes available for the 650 Versys:


  • Front 120/70R17
  • Rear 150/70R17
  • Rear 170/60R17

Stock tire sizes for the 2009 KLE650:

  • Front 120/70 ZR17 M/C (58W)
  • Rear 160/60 ZR17 M/C (69W)
Shinko 170/60R17


Continental Trail Attack 2 at 10,000km


Oh happy day!


Now to get these in to Centennial Honda in Summerside!

I'm also in the middle of installing new chain and sprockets, a 16 tooth front that is supposed to correct the speedometer and give me slightly better fuel economy, but mostly because I keep trying to find an extra gear when on the highway. If I can still power wheelie in first, I'll be a happy camper! JT sprockets and chain from fortnine.ca

I'm off to get the tires installed and balanced! 

Cheers!

I got back, got the tires mounted, whipped off the old front and rear sprockets and cut down a 118 link chain to match the 114 that I'd just taken off, and found that with the adjusters ALL the way in I could just get the master link in and riveted. In future I'd leave it at 116 then you can play with both sprocket sizes if you had the desire to do so. Speaking of which, you probably want to see some part numbers to know what I was playing with. They are all JT steel products, most of which I purchased through FortNine.ca with free shipping.
  • Front Sprocket JTF565-16 (OEM standard is 15 tooth)
  • Rear Sprocket  JTR478-46 (OEM standard 46 tooth)
  • Chain JTC520X1R2 118DL (114 links fits the above sprocket combo JUST)
I am going to stop using Maxima Chain Wax
 I'm going to start using a paint brush and some SAE 90W or some chainsaw bar oil instead of Maxima Chain Wax as I find that coupled with the dust and dirt of gravel roads, it becomes a pasty grinding compound and I'm convinced that it shortens the life of my chains. Most of it is getting flung off onto my front sprocket cover. lol.

You won't see it this clena ever again. 

Fresh, unstretched chain, it's a challenge, don't you think?


The Tires:

How does the bike ride with the new tires? On gravel there is giggle factor. Wide open throttle and I rocket forward with little slip. Power wheelies on gravel are possible and pretty epic on the hard packed dirt, and a bit squirrely on the loose stuff. Rear braking is a lot more aggressive than it was with the Contis, as those tires you kind of felt like the Energizer bunny trying to slow down, but when you chop that rear brake with brand new 705s, you definitely slow down faster, and need to alternate between full lock and threshold as the rear will want to skate a bit. I felt much more confident running up to my usual 100 kph on the dirt road near my place, and I was able to stay on throttle closer to the stop rather than coast in gingerly as I did on the Contis.

There is more noise noticeable at low speeds on pavement. As soon as you hit third gear and roll on, it fades into the engine and wind noise. It was a short trip/rip so I can't comment about vibration yet.

Turn in at slow speeds is fast, in fact after scrubbing the shoulders off on my Contis in Nova Scotia, it seemed a bit twitchy, but that was a first impression, and I found the front quite well sorted, and with the wider rear, the bike tips into the corners with a tad more effort. Remember these are new and I haven't scrubbed them in, so I'll have more once I've done some wet weather and long distance on them.

The sprockets: 

Have you been on the highway and tried to hit 7th gear? After this mod you won't need to. The 16 tooth (+1) /46 tooth (Stock) combo is a recommended mod by those on the Versys forum in the know, and I've been wanting but hesitating for a while now, and had it sitting in my tool box for a couple of years now, and today was the day! I can still power wheelie in first, and skip through third gear after winding up in second, but on the 80km/h posted back roads, I found I was cruising them in 5th as opposed to 6th gear! Once I hit top, I was cruising at 4500 rpm just ticking along at 97kph. Once I hit 5000 rpm, I was at an indicated 110kph with more then 2/3 throttle to go. I can easily see why the guys on the forum recommend this for touring. It just feels right, and should settle the bike down for those long boring runs on the highway, yet still leave it with enough snort to climb hills with aplomb. If I don't like it, six bolts and I'm back to a 15 tooth stock front.

Update on the front sprocket 2017-09-11:

 I now think that if the majority of your riding is done in a relatively flat area with minor elevation changes and most of that is on paved road, then you will love this mod.Read on:

If you ride a lot of gravel roads, forestry, logging, access roads or live where the roads climb up and down hills, then I would stick with the 15 tooth sprocket so that each gear has more power. In the gravel I was finding myself in spots where I wanted extra oomph to get the front to lighten up in deep gravel or across potholes and it just wasn't on tap at the throttle because of the gearing.
Climbing hills it felt like I was on a 600 sportbike, down two, up one, up one, down one. repeat, whereas the stock combo, the windscreen would shake and rattle as that engine would work to make the bike do what you should have dropped a gear for. I'd say if you ride in the mountains or foothills, leave it as is with the stock ratios.

Update on the Shinko 705s 2017-09-11:

After having put 1200km on the Shinko 705 combo of mud, gravel, both wet and dry pavement and hard cornering on mountain roads this past weekend riding the Cabot Trail on Cape Breton Island Nova Scotia, I have this to say about them:

  • Noise - yes, they are noisy. You will hear it, but it's easy to call it part of the background. If you are the type to madly search google for "Fairing Buzz" and are willing to spends hundreds of dollars to solve it, then get a set of Continental Motion Tires, or look at the Shinko Raven series instead.
  • Vibration - Yes, there seems to be a bit more vibration, but I used to iron butt on a KLR wth Kenda 270s. Any KLR owner would laugh at this. Go buy yourself a BMW. Sorry, cheap shot. They are minimal and I felt more vibration from the engine and my choice of gear for the new 16 tooth front sprocket. 
  • Traction on pavement - no issues wet or dry, in fact I managed a brief power wheelie on a wet road. I got some decent lean angles, and went 360 degrees around a perfect roundabout for the sheer joy of it and felt confident as I scraped a peg after having ridden on them for two days and 11,000 km. I wouldn't ride these tires like I owned a track bike, but that is me. 
  • Traction on gravel / dirt - if you apply the brake, the rear will lock up and slow you down, perhaps not as fast as you would like, but much more aggressively than Michelin PR4s and Conti Trail Attack2 tires, for sure. You feel much more in control stopping on a gravel road. These aren't knobbies, and with a round profile, as you lean the bike they will tend to roll out from underneath the bike, perhaps more slowly than less aggressive tires. The same rule applies, wicked fast in the straights, slow down for the turns or end up in the ditch. You can power wheelie on hard packed dirt or dry grass, and that is wicked!
  • Traction in mud - not tested in deep mud, but they give you a bit of thrust forward before they fill up and become slicks. I've really only ridden muddy gravel roads, and a few bigger potholes that have clay bottoms. 
  • Traction in sand - Ah. Good luck, you get push from the rear, but that wide front will go when the sand gets deeper. Get a DR400 or an XR650L.
  • Cornering and transitions - The odd size combo does have an effect, as the front tips in but the back end seems lazy. It's not as good as the oem 120f 160r combo, but it works. It tames the Versys down a bit, and on a new tire profile, it was hardly noticeable by the end of today's ride. I'll know more once the shoulders wear more and the turn in changes. Performs well with moderate trail braking. 
  • Feel / Feedback - What is meant by that? I felt that the front tire was skating sideways on the gravel slope, so I gave it  a whack of throttle, and the rear tire thrust the bike forward, the front began to track correctly. 
  • Logevity / mileage - Give me a break, I've only just worn the rubber nipples off of them! :)
Note that I had touring luggage on the bike at all times during the testing.

Lost the front end twice coming up this steep grade in this built up gravel.
Note: If you are planning to ride your Versys off road, then look at my posts on fork seals, as you are going to want to learn how to clean those pesky buggers well, or keep your mechanics phone number in your pocket. 



What tires are you running on your bike?
