Need a 17 inch rear knobby tyre
« on: May 19, 2008, 02:51:39 pm »
Fellow VMX'ers, lend me your ears and promise not to laugh!

I'm chasing a 17 inch rear knobby for my SL100 powerthruster project. In keeping with the theme of my budget projects a near new to half worn tyre would be ideal. 3.50x17 is minimum size required and the max size about a 4.10x17 any help greatly appreciated. A bit of age hardening and or slight perishing is quite okay   :)

Just noticed your after 3.50x17 minimum so the 325 will be no good. I do have a modern type uni tyre 450 x 17 with good tread. Semi knobby sorta thing.

Take the 3.25 the light weight does make a difference on a little 100 , yes really! I try to find them in 17 and 18.  Doc the 18inch SL125 wheels go straight in as does the CT125/200 agi  (with ct brake backing plate ) are easier to find heaps of tyres for. Tim
I may not agree with what you have to say, but I'll defend to the death your right to say it.

Walter thanks but no thanks, maybe if it were an SL1000 I'd be inclined to go that way :D

Quicky, that could be the go! Most 3.25 I've seen all looked like fronts and not really suitable. It would appear that tyre is a Yokahama maybe? She'd do nicely..I don't think those knobs would be too aggressive for the little 100 to keep buzzing along :P a chunky new tyre in near any size on the rear would bog it down needlessly. I fitted a near new 19inch Pirelli Scorpion on the front today courtesy of Dodgee and it feels like it should stick like poo. Sold!..(soon as some funding arrives in the next week or so I'll be intouch ;))

Tim, no problems. Onto the 18 inch CT125 rear wheel already (as fitted in picture). While it does fit nicely I'm going to be a little anal here in saying I wanted to keep the 17rear 19 front combination in favour of of the 18/21 as most people would suggest. The reason for this :-\ The SL/XL/CT/CR125 wheels are dimensionally a fraction bigger in most areas if one looks closely. Try swapping the 100 brake hubs into the 125 wheels and it becomes even more evident. Add this to the slightly longer spokes and it increases the unsprung weight a little. The heavier the unsprung weight the more resistance it will have to want to turn once the wheels are in motion blah blah blah dribble dribble. It is only a 100 after all I know and this all sounds like shit but add another saving by using an alloy rear sprocket and throw in my physical size I reckon it'll handle better setup as a midi rather than the full size 125. The 18" rear I have fitted now I'll keep for a spare fitted with a trial universal for DT. As usual I'm arse about, I'll get the thing riding half decently first and only after this will work on the engine begin ;)



shhh..but those orange springs are the real secret to going faster on a Honda! ;D It'll be a slug no matter but no reason why it can't be a fun slug ;)

Gee's Doc. You have that little Honda looking good.
The tyre just a Cheng shin mate and your its new owner.  ;)

Thanks Quicky. Cheng shin, that's good, it has quite few brothers and sisters living here already so it won't be lonely unlike the poor ol' pirelli  :D trying the keep the SL patina-ish but damn it's hard when I'm a meddler! I wanna do a number on it but I like it too much how it is now ::) I keep picturing an oil cooler hanging off those front downtubes though  :P
