You like that navel, don't you Chris... you want that navel, don't you ... Chris.
You want to do that fat bastard tattoo in the ass, don't you Chris... you do, don't you...
And GA. DUALSPORT WANTAB, I'm really sorry ChrisC turned your thread into a gay fetish porn thing.
Back to tires, Damnit!
Thanks guys, I have some ideas now. Guess I will have to try some and see what floats my boat best. later!
Back on track here and away from fly ridden belly orifices...
I ordered my TKC80's (front and rear) yesterday and should have them on this weekend... Will let you know how I like them.
Also, a reccomendation for a shope here in Elk Grove, CA called NorCal Motorsports. Just a small place that works on dirtbikes (quite good at suspensions I understand) located in a barn behind his house off of Elk Grove - Florin Road. He is the kind of guy who doesn't care if you buy your tires elsewhere and he mounts them for you - at the same time he is willing to give you internet pricing if you buy from him. Cool guy and I hear good things about his work.
Sorry to revive an old thread. I am looking at getting some Shinko 244s shipped for my KTM 625 SXC and couldn't find a more specific existing thread for my inquiry.
My main question is about tyre size conversions which I understand in theory but want to be 100% sure about in practice. Skip to the bottom for more info about the riding that I do and plan to do.
The 625sxc KTM tyre specs are as follows:
Front 90/90-21 M/C 54R
Rear 140/80-18 M/C 70M
My naive attempt at conversion indicates that the following tyres will fit:
4.60x18 (63P) Tube Type Shinko 244 Series Dual Sport Tire
3.00x21 (51L) Tube Type Shinko 244 Series Dual Sport Tire
Can anybody confirm this? It's very important that I get this right
Thanks for your time
I have been doing a bit of trail-riding and am hoping to do a fair bit more and develop strong skills. I am currently using the Pirelli Scorpion A/T tyres that the last owner had on my bike. They do ok on hardpack and rocks but start to suffer when things get loose and are literally useless in the mud. This is compounded by the fact that the tyres are wearing down.
I don't expect an amazing all-round tyre, but I'd like to move to something economical with a 60/40 or 50/50 road/trail bias. I'm looking closely and getting multiple sets of the Shinko 244 to fill this need.
I want something that can deal reasonably well with the road (more in terms of mileage than performance) while being better for the trail where I hold back a lot less. Camping trips are probably in my future but for the most part the bike will be unloaded with a sub-80kg rider
Although I'm not looking for a wet-offroad tyre, It was actually damp dirt that made me realise I need something better. Even on moderate descents at low speed the wheels lock up instantly where my friend with newish K60s on his DR650 was getting a lot more traction all around.
You want the 5.10 rear, and even that is only equivalent to a 130/80. It will work, but it will gear the bike down, drop the rear of the bike and lower the seat height. The gearing is the most noticeable change and the biggest negative.
The trouble with all the cheap Asian tyres is that they don't tend to make them in the big 140/80 size, which is more the domain of the Euro dirt bikes.
You are a legend Warewolf!
I will be grabbing some new sprockets (+everything I will foresee-ably want to minimise shipping costs) so the gearing won't be a problem. Would you imagine that the difference would be mitigated by going up a tooth on the front sprocket?
Shinko looks like they have some 'big block' clones but they are only available for the 990 and above. It's a shame as the tread pattern seems like the best compromise for a 50/50 high mileage tyre.
Thanks again, you've really helped me out!
Are you bringing the Shinko's in yourself or through a dealer? I guess they are cheap? keep us informed.
Theoretically - that is, computed by the published numbers - the difference between the two tyre sizes is 2.5%. Note that the 10 mm tread depth difference between new 13 mm vs worn 3 mm (often the advised rear minimum) is about 3.0% too.
Going +1 tooth on the front is about 6-7%. My gut feel (watching the tacho) is that the 130/80 and 5.10 are actually closer to this figure than the 2.5% computed above. I'm currently running my first SR244 5.10-18 and it has certainly short-geared the bike.
One more positive of the smaller tyre is faster turning.
Yes, that is the problem. Most Asian manufacturers make small-bike tyres: all sorts of tiny sizes and ranging up to 130/80 or 5.10. But then they might make what I call "GS class" tyres: 19 or 21 fronts, with matching 17" rears (esp. 150/70-17). The 140/80-18 doesn't appear on their radar.
I'm bringing them in through the jakewilson group. The 244s are under $120 AUD for a set!
If you are willing to look past the snobbery and China-phobia, there are some who believe they are among the best 50/50 tyres out there. I'm planning on getting 3 rears and 2 fronts which should last me until I upgrade bikes.
Postage is steep, but if you are ordering $600 worth of goods it really pays off to buy everything you know you'll want for the next year or two. I'm also planning to grab a set of doubletake mirrors (my single 'indulgence') which are about $55 cheaper than the next cheapest price (shipped), plus miscellaneous consumables. It makes sense to stock up on things like filters and sprockets as you know you'll need them.
Usually I'll add and remove stuff from my cart over the course of a month to think about what I will really need and develop a keen sense of what needs replacing or improving.
It is an exercise in foresight and restraint
