Widening a motorcycle rim

[Rikkido]

Hi guys,
Anyone know who widens motorcycle rims in auckland? I want to put a 150/60 tyre on the rear of my Ninja, so I need the rim widened atleast half an inch, one inch would be ideal.

Why on earth would you want to do that? The little 250 won't put out enough power to worry a 150. And it would be in imbalance with the front. Consider that RS125 GP bikes that touch 50hp run 120 rear tyres in race conditions.

Besides you won't get a warrant ever again. Spend the money on some decent tyres in the correct size.

I wouldn't expect a 150 to fit in the swing arm?
It'd look nice, yes. Will make it handle worse.

I've got 150/70 on it now, it feels nicer with the wider tyre I just thought a rim to match and a lower profile would be better. The 130/70 profile is 91mm, the 150/60 profile is 90mm but the 150/70 I have on now is 105mm. Thats not taking into account the tyre bending but I see your point.

And I was just thinking because the bike is in the shop anyway.

with no question of a doubt you have made it worse by overtyring it. Well documented, the odd shape will give you less rubber on the road. If it is taller it will make the bike tip in quicker, but you could probably achieve the same thing with the forks through the clamps. Whether it remains stable is another question.

Save up for some decent tyres in the right sizes.

Some of the Hornet 250's I have seen have 180's on the rear...makes no sense at all.

Looks good.
Harley's do not need fat tyres (all they need is a sturdy chain and hoist IYKWIM)

its coz they are fireblade rims
same as the 600 hornets a rim designed for a 180 is fine,
when im real broke(usually always )
ill fit what ever i can afford somtimes 190 or 170 yes it changes the characteristics but i ride accordingly
