240mm rear tire or similar setup questions

I think over this winter a friend and I might be taking a bike down the road of a sportbike cruiser instead of a canyon carver. I have been looking at various bike mags and have seen 240mm or a little smaller/bigger with the appropriate swing arm. Similar to what's on this bike:

Question is, are there kits available to install a tire that wide on the back or do parts have to be gathered individually?

240 is way too small to make a significant improvement on your Starbucks parking lot status. Go atleast 300.

dam if were really talking starbucks status he gonna need atleast 20 inch spinners that keep spinning when he stops.

other then that the idea of seeing a 240 makes me wanna suicide or atleast buy a different brand bike.

The isn't necessarily true. The early 250 kits did have the tire offset. With the use of a 240 that isn't the case provided a properly built arm is used.

I agree a 300 looks better however I generally recommend a 240 as most competent riders will not have a problem cornering with a 240. The same can not be said for the 280 and up tires.

One must keep in mind that not everyone lives in a canyon filled region. Next I see most riders are unable to ride most of these bikes to their full potential to start with. So adding swing arm length or width really isn't handicapping them. Those of you who can "really" ride would not have a problem with a 240. After an hour or so on the bike you'll be right out to the edge of the chicken strip.

I seen a guy stunt on a sportster, what a waste of a perfectly good harley....YOU should tell him he is wasting it and get a gixxxxxer 7fiddy

Why do they market sport bikes like they do, is it because everyone and their brother (or sister) is at the track? No, its because they went to starbucks instead (Taco bell here)....at least you know this guy isnt going to be riding like a total f'ing turd on one wheel everywhere like every other jackfuck with a stock bike i see around.

Different strokes for different folks. If done right a bike with a 300mm rear looks ALMOST as good as a fully built K5 track bike. Both dead sexy though. :drool

Most of your more reputable companies will offer you a complete package.

I used RC Components on the last few customer builds and I have been very happy with them. Having built my own arms prior to using one of theirs I must admit they do nice work (Not that the others don't).

How the heck do you get chain clearance without offsetting the wheel?

I'd say it's very easy to get edge to edge of a 240/300 rear while cornering - because it's such a low profile you don't have to lean the bike over very far to do it. On the contrary, gettting to the edge of a 180 is a lot harder, the tire profile is more of a dome than flat. The issue of a big ol' donut back there is unsprung weight and clearance.

With a 240 the offset comes from the front sprocket. Remember the 250 kits and "clearancing" the frames? That is no longer done. The use of the 240 (at least the RC Comp kit) puts the tire dead center. On a side note in reference to tires being centered, there are factory bikes that come offset some. This is done to be in the center of the weight (balanced) not center of the bike.

The 240 when inflated properly is very round as opposed to flat. The contact patch is not much larger than that of a 180 (that is where I usually bust there chops). Rim width choice plays a part in this also. While the standard rim for a 240 is a 8 1/2" wheel I have seen the larger tires on rims with an inch difference between them which consequently affects its "foot print".

Unsprung weight.... There is no doubt they are heavy. Aside form Carbon Fiber or Magnesium I don't for see a light weight rim with any width gaining any popularity. You certainly won't win any light weight contests with the aftermarket wheels.

Sorry, I'm not familiar with the wide tire kits which is why I asked. I hope there's some sort of serious support bolted on if you're offsetting at the front sprocket. Sounds like an awful lot of strain on the output shaft.

A quick google showed me the popular sizes are 240/40 and 300/35, both much flatter profiles than a 50 or 55 "normal" rear. It's still rounded, but flatter in comparison. You get the point.

That shits funny looking. A snapshot isn't much of an indicator that the bike performs well (good rider on it or not). Given the shape of the rear tire and how far back the wheel is I'm quite sure that thing is just great at holding an inside like.

Goldwings make for great stunt bikes too :)
