paul-666 Posted June 16, 2013 Share Posted June 16, 2013 Could I swap the rear wheel on my 125 ybr for the rear wheel on a ybr 250 ? I know the swing arm is different but the breaks are the same what else do I need to look up on this before starting anything ? Link to comment Share on other sites More sharing options...
Chazillor Posted June 16, 2013 Share Posted June 16, 2013 Most important question would be why? Link to comment Share on other sites More sharing options...

bippo Posted June 17, 2013 Share Posted June 17, 2013 I never had a problem with the Pilot Sporty tyres - not sure if you have them on your YBR Paul?Rode through winter without concerns over grip, and you can get a decent lean on them too. Compare them against the original tyres and you can see how different they are. Link to comment Share on other sites More sharing options...
Tommy xs Posted June 17, 2013 Share Posted June 17, 2013 there's a lot to consider, for starters I imagine it would have a heaver sprocket and unless the width of to swing-arm's are the same & the Hubs, you will need custom made spacers so the sprockets align, then you would have to figure out if you can change the front sprocket & chain suppose it could be done but like chazillor said WHY!! much easier to follow bippos advice tyre's Link to comment Share on other sites More sharing options...
Chazillor Posted June 17, 2013 Share Posted June 17, 2013 Yeah I know what you mean about it, they are so narrow when you look at them lol. As others have said though, Michelin Pilot Sporty tyres are fantastic. Rode all through the winter without wanting for more grip, those are a great investment before you go down the road of what would be a colossal ballache.

paul-666 Posted June 17, 2013 Author Share Posted June 17, 2013 There's nothing wrong with it the tyres I have on are great I only missed 7 days over winter due to bad snow on the main roads so there's no problem there I just wanted to know what I needed to look at to do this as the rear wheel is only 90/90 18"and the 250 is 130/70 17" so there's a canny bit more rubber to keep you on the up right if you know what I mean Link to comment Share on other sites More sharing options...
bippo Posted June 17, 2013 Share Posted June 17, 2013 Just note that your smaller tyres will be better at carving through any snow etc, seeing as you're a winter rider.I went to a Mini show in my classic Cooper Sport once, it had been raining heavily a few days before and the field we were parking in was muddy. My car got stuck because of the fat wheels. Managed to get it out by sticking it in 2nd and rocking it. Sprayed the Mini behind me who then strolled round me with their skinny (standard) wheels. Oops...You also have to consider the additional weight and affect on speed etc. You've already mentioned that your YBR struggles up the hill to your house, so I'm not sure if this will help or hinder matters.
