Wide rear tire honda nighthawk 1984

1984 honda nighthawk 650sc
I want a wide rear tire on this thing. How would I go about putting one on and where would I get the parts?

Due to the way the shaft drive swingarm is constructed, you're rather limited in how wide it can go. You would need to get a wider rear wheel as well in 17"; the only significantly wider donor I've heard of that can swap in is the one off the NT700.

Any of the current generation NT700V will apparently work. The rear will mount a 150/50-17.

Good luck finding a nt700 final drive unless you're willing to pay through the nose to ship one off a Deauville across the pond. Honda just didn't sell that many here and considering the market demographic, there aren't going to be many donors. You might have better luck with a Shadow unit. It's already got twin shocks too.

My question is why? For maybe one inch more wheel? I love to mod things but sometimes I've needed to be reminded of the diminishing return on my proposed project. Now It's your turn.

This bike is 30 years old. Just ride the thing and be happy.

According to the guy building a retromod 700S (same drive as the 650 in question), it just slides right on. Don't need the NT700V's final drive at all, just the wheel per him.

Quote:
The inspiration to make this change came from the work on the PC800. For that left side shaft bike, I wanted to upgrade the wheels to 17" front and rear (it had 15" in the rear stock) so I could get modern radial tires on. After much research, I selected the NT650V wheels. Trouble was it was never imported to the US, so I went to UK.eBay to get the wheels. The cost of shipping was high, but the wheels were not too bad. After getting the swap worked out - including the rear brake - I solved my challenge on the PC800. THat matched up well with the front suspension swap from a CBR600 F4 (and brakes).

Looking at the CB700SC, I noted it too had a left side shaft set up. So, I pulled the NT650V (curved spoke) wheels of and tried them on the CB700SC. The rear just bolts up, it looks stock. The front was not a good match because of the stock suspension. Once I knew they would work, I mail ordered a set of new NT700V wheels as they imported that bike to the US. These wheels had straight spokes, so they are in character with the stock wheels.
Original source: http://groups.yahoo.com/neo/groups/h...thawk700s/info - though he is on the Nighthawk forum as well. There are more than a couple shaft-drive Nighthawk people who have done the conversion since.

Remember, Honda is inordinately fond of parts-bin engineering...

Curiosity and the neighborhood where I live has cracks that I keep getting caught in.
On a slightly unrelated note; what about a wider front tire?

Have to do a front end swap, from triple trees down. Can't get it to work otherwise.
