I've just acquired a nice 73 T150v from a forum member. I am looking to change the old dry K81s, and am wondering if anyone recommends a "newer" style tire- or if i should stick with stock. I just do normal street riding in good weather. Thanks in advance. Tony
Tony- I recently finished restoring a 1975 T160 that I purchased two years ago. The previous owner had installed Road Rider tires front and rear, that didn't have two hundred miles on them when I bought the bike. When I finally got the bike running and on the road I noticed cracks in the sidewalls of both tires. Checking the date of manufacture stamped into the sidewall one tire indicated it had been manufactured in 2006 and the other in 2008! Searching around I discovered that Continental will be producing a radial tire with sizes to fit our bikes sometime later this year. Not wanting to take a chance on destroying my bike I decided to buy a set of cheap tires until the radials come out so I purchased a set of Shinko Tour Masters, 100x90/19 front and 110x90x19 rear. I just cant believe what a great tire they are and dirt cheap at 125.00 for the pair!!!! I have close to 1,000 miles on them and they hardly show any wear, and the bike handles great on them on both wet and dry roads. I have always used Dunlop and Avon's and just cant get over how well the bike handles on these. I know most guys will turn their noses up at these, (I did!!)until I tried them. If your on a tight budget you might check into these, good luck.

Mmmm ... I was going to refer Tony to Continental in my first post but, while they've offered a 100/90R19 front ClassicAttack for a while, both available rears are 18". Conti have been threatening a 110/85R19 rear for triples, Commandos, etc. for a while but I'd sooner see 'em make good than hold my breath.

It steepens the head angle slightly and ime, that can be enough to set off speed wobbles/weaves - note that, while Continental have increased the width (110) of the planned 19" rear ClassicAttack, they've reduced the height percentage (85) so the o.d. will be similar to an original 4.10x19 (100/90x19).
Note also I'm not saying altering tyre o.d. will lead to handling problems - good or bad handling is down to numerous factors - I'm just saying that, possibly if you aren't very heavy and/or you go for the different weight distribution of flatter and narrower 'bars, ime it might, particularly if you were ... err ... exploring the performance potential ...
Hello Stuart- Yea I was concerned about changing the overall geometry when I started searching for replacement tires, the last thing I wanted to do was start speed wobbles so I did compare what the manufactures listed for their tire dimensions prior to making any purchase. I also took a tape measure to compare what they listed and what the actual mounted dimensions are. The front tire was similar but the rear was only slightly taller which I was looking for to slow the engine down a bit at cruising speeds. If I were too concerned about exploring the performance potential the first thing I would do is try and loose the forty pounds I have packed on since I retired :-)!!!! My other bike is an Aprilia Haga Replica so if I feel the need to scare the myself I ride that. I ride the T160 rather conservatively and just really enjoy how well it handles and corners. I always come back with a grin on my face.
i went into a speed wobble on my T120, which i believe was likely due to my cheng shin K81 clone on the front.
got rid of it and haven't fallen down at 110-mph since.
Into the distance a ribbon of black Stretched to the point of no turning back A flight of fancy on a windswept field Standing alone my senses reeled A fatal attraction is holding me fast how How can I escape this irresistible grasp?
Adam, you are correct. The Shinko 110/90X19 is advertised for front tire use. Prior to purchasing my tires I contacted Shinko via their web site and asked specifically if it could be used as a rear tire application. I was advised that although they could not say yes, the did say "many purchasers have used them as a rear tire application with excellent results".
I have well over one thousand miles on my set, many at highway speeds in excess of 70-75 MPH and have been more than satisfied with the wear and handling. As I stated earlier, the set I purchased was only intended to be a temporary replacement for the dry rotted Avon's fitted to my bike when I purchased it. I don't ride my bike hard so I was not very concerned about having the ultimate handling tire that would allow me to drag the pegs thru the turns. I was more concerned of having a safer set of tires under my ass without spending a bunch of money at the time. Would I buy another set? Yes, as they definitely offer us an alternative to much more expensive tires. The decision is totally up to each individual and what their intended use of their bike will be. Hope this helps.
