Anyone know how big we can go on the stock rear wheel and swing arm? It's an '81 and currently has a 110/90-18 rear.

You can get wider rims from other 450 models and they would be a bolt-on. Here are a few dimensions from 1981 for instance.

Ok so I thought the stock rear tyre being a 3.50-18 meant the new metric "equivalent" is a 100/90-18, not a 110/90-18. Is that right?
If so, wouldn't the 110/90-18 be pushing it already?
I get confused with the conversion there so I'm possibly way off...

My '80 450E has a 120/90-18 Kenda Challenger (was on it when I bought it) . That's about all I think will fit. It's very close to the swingarm.

Tech7 that's what I was looking for. I'm trying to decide between the Avon Road Rider or the Bridgestone Spitfire. I really like the Avon, but I can get the pair of Spitfires for the a little over the cost of the rear Avon.

Pretty sure I'm going to go with a 120/90-18 rear and probably a 100/90-18 front.
Good luck.
Remember, "bigger" is not always "better". That was pointed out very early in this thread.
Please don't blame us if you are disappointed with the (lack of) traction in your wider-than-it-should-be tire.

Well, Ed, we have done what we can. :-\\\Ya can lead a horse to water but you can't make them drink.
All we can do now is to sit back and see if he survives the too-large tire long enough to post his results.

Besides rubbing on the swingarm or the fenders, what else could go wrong with a larger sized tire? I think I know the answer but just looking for confirmation.

Steve,
He's not going to crash out from going over sized on a tire by one or two sizes. Definitely a matter of looks over performance though, although bulging sidewalls are are more dorky than a skinny tire to me.

The wheel rim is too narrow for the tire,pinching the bead and causing the sidewalls to distort and the tread to be more curved than designed. So, you actually end up with less tread on the road (due to the distorted curvature) and you handling gets messed up (back tire tries to lean faster than the front)
So, you can spoon in whatever fits in the physical space, but it just makes things worse instead of better.
That's why the wider rim was suggested
That is a nice looking bike, Tech. Show us more please.
