I am thinking about going to the darkside. Does anyone have any pics of a Custom that has went to the darkside? I have looked around and can not find any. Thanks
This was not the first time i have heard of this happening. I was talking to my dealer while having some stuff installed on my custom and the subject of "darkside" came up.Join Date: Sep 2009
just so everyone following this post knows, i have since taken the car tire off. at 85 the bike would wobble so bad it almost wrecked me. i swallowed my pride and decided the nay sayers were right on this one. i ordered a metzler 880 and slung it back on and holy crap, it handles like the amazing motorcycle that i fell in love with and bought 2 years ago, except better because now instead of those terrible dunlops i now have a wonderful front and rear set of metzlers. please, before going darkside get a set of metzlers and try them out for tread life. my dad has a big tour deluxe and has almost 12000 miles on his rear metzler and easily has another 4000 before he has to think about another, not to mention his front which is still tickin along. i do not support this mod anymore, especially since after i took off the car tire i saw there were exposed radials on the interior of the tire, probably from having to increase the pressure to 100lbs before the bead would seat. if its for you then it is, but it was not for me, and there are quality motorcycle tires out there that will surprise you. if you decide that darkside is right for you, just stay away from those cheap ass altimax HPs and be careful around freeway speeds. thank you.
Steve..you're spot on with this. It's the weight of the bike that is suspect in the wobbling. A car tire is designed to carry more weight than a bike, thus, with speed it will alter contour and any imbalance will show up in wobbling or shimmying. With a four wheeler, you have it too, but also have four tires countering each other. Not so on a bike, the one tire will dominate with its characteristics. Had the rider with the wobbling changed the tire again he would have gotten a different result. I made sure mine was balanced before installing. The tire shop couldn't, so I got two 5gal buckets stabilized and used my axle and turned the tire with reference marks until it would not move at any position. Make sure your bearings are lubed and free rolling to do this, or barely roll the shaft back and forth to see if the tire moves. This is critical in high speeds.I have a friend with a Rocket III that's been Darkside for 3 years now. I think the problem described above is speed/weight related. He experiences what he calls tire egging at about 120 mph. The diameter of the tire fluctuates quickly causing the bike to buck terribly. The Rocket is a much heavier bike than our 9ers so maybe we would feel the effect at lower speeds? Anyway, he just stopped topping 100 mph and continued down the dark road.
Keep 'em upright! Later...
Bear in mind the triumph is a 803 lb (wet) motorcycle vs the 641 lb 900. This definatly would be a different handling motorcycle vs stock and not one that novices should deal with. It does not solve the wobbles issue , at 80 mph plus speeds.Oldturer, until you see it in action most people expect a bike to ride the sidewalls thru the twisties. Couldn't be further from the truth. When Rocket first put his Darkside tire on I followed him quite a bit (with 2300cc's I'm usually following...). The sidewalls flex so much that even dragging pegs he's got 3/4 of the flat tread on the ground. If you know anyone running Darkside. Make it a point to follow them for a while and watch the way the tire performs. It's astounding!
57, that is my tire and yes, it is an optical illusion. The tire is the limit on wide side, but it doesn't rub at all. It has 40lbs as I pull a trailer and usually ride two up. So far so good, I actually love the handle and have already gotten used to it. I've been on gravel, rain, steep sided curves and rough road..it well out performed the MC that came on the bike. You all mentioned the weight of the Rocket versus the 900...this is true, the care tire is rated for more weight. My bike weighs 896 without trailer or two up and handles fantastic with the car tire.Bear in mind the triumph is a 803 lb (wet) motorcycle vs the 641 lb 900.

As many have had issues sealing the bead, I'm also not convinced that the sidewall flexing and undo pressure on the bead is a good or safe thing.
BTW, maybe its me or an optical thing, but this tire looks cupped inwards in the center and appears to be under inflated.
I for one begrudge the high price of motorcycle tires and their short life expectancy but I'm not yet convinced that going darkside is the answer.
