    Thanks - there is lots of info here and on hondatwins. There is alot of info out there - its not all accurate, so you really have to make your own decisions based on what you find and what your intend for your application. Your bike looks like its coming together, keep with it and get it...

    My CB450 Project

    I haven't experienced any problems since removing that piece. I did ask Team Hansen about it, they said no problems with removing it. (this isn't a race bike). I think its ok as long as the rear of the frame is tied together with a hoop.

    My CB450 Project

    Tank painted. Had a local custom shop do it. Nice metallic brown with red striping. I love it. It sits nice and low and flows with the bike. But I ran into an issue with the spigot and the carbs. I had to make a special fitting that was short so the fuel hose could clear without kinking. I wound...

    My CB450 Project

    Here is a pic with the CB750 swingarm. You can see there is a lot more clearance to the rear frame, allowing full suspension travel. I realize I made a mistake by selecting the CRF rear hub. I had a hard time finding a rear sprocket that wouldn't completely screw up the ratios. Mocking up...

    My CB450 Project

    I am missing some pics but here we are. Frame and CB750 swingarm were powdercoated. Its kind of a pewter color with metallic in it. Motor in. You can also see the 2 little tabs I added for the rear brake master cylinder. I had also cut down the rearset mounts, the CBR pieces only needed 1 bolt...

    My CB450 Project

    Ok I remember why I made the change to the CB750 swingarm. The rear hub was too wide and there was no room for the sprocket between the hub and swingarm/shock. The CB750 swingarm is much wider at the rear axle and allowed clearance for the sprocket. With the tire I was running, I also needed an...

    My CB450 Project

    I encountered issues with the front brake caliper interfering with the wheel spokes. The Rad Mfg hubs are wide, they are intended for supermoto applications. I attacked it 2 ways. I made spacers to move the caliper out radially, so its now further away from the axle. I spaced it as much as I...

    Wheels and tires. I contacted Rad Mfg and they made me a front hub to fit the GSXR rotor and axle. The rear hub is from a CRF450 to fit the rear rotor I chose. It has a cush drive so it will be durable on the street. The engine shown in these pics is a stuck motor from a junkyard. Its just...

    My CB450 Project

    Welded on new rear set mounts. Removed old rear fender mount (looked like a brace on rear frame). I chose aftermarket rear sets from a CBR600RR, because they had short mounts that wouldn't position my feet too far rearward. Headlight mounts. I used a stock CB450 bucket, but modified it to fit...

    My CB450 Project

    I wound up using shocks from a 90's Kawasaki ZRX1100. They are adjustable and about an inch longer than the OEM shock, which is longer than the Works pieces I had. But the lower mount is an eye, and the stock CB450 is a fork. I also sourced a CB750 swingarm for several reasons. Its stiffer...

    My CB450 Project

    My idea for this bike was to apply some modern tech (carbon seat) to make a mix of old and new. I purchased a used front end assembly from a 2007 GSXR750 and worked to adapt it to the CB450 frame. The GSXR front end has black adjustable upside down forks, which I knew would look great and offer...

    My CB450 Project

    I then began working to find the right tank. I thought I wanted a CX500 Deluxe tank, but after mocking it up, I just couldn't get it to do what I wanted. Its an inch or 2 longer than the CB450 tank, and I couldn't get it to sit the way I wanted. Its also really wide. I also tried a CB200 tank...

    My CB450 Project

    I really wanted a brushed finish on the engine. I did not want mirror polish or black paint. I spent hours scrubbing with scotch brite and steel wool to get the finish I wanted. Then I tried several different clear coat paints to see if they would stick. I believe I had the best result with...

    My CB450 Project

    Some "after" pics. I reused the pistons. There was some pitting, but I thought it would be ok. Had the head powder coated high temp black but left the cam area brushed/natural. Turned out pretty good. I instructed the powder coater about what I was looking for and they did a great job with it.

    Stripped the bike down, and removed the rear passenger peg brackets, battery box Stripped the gray paint from the engine and planned to freshen it up. Valve seats looked a little beat up. Bores looked ok so I just planned to hone them and replace the piston rings.

    My CB450 Project

    Hi guys - just wanted to share my build. I started it in 2009 and its been a long process... It was a running bike when I bought it. I knew I wanted a bike that would perform and look like it was built for speed. I actually did most of the work in 2010 and 2011, but I'm just now getting to...

    WTB: CB450 engine - cases in particular

    WTB: CB450 engine - cases in particular

    My CB450 engine cases are cracked near the kickstart spring, so I am looking to either bolt in a complete running engine, or swap the cases. I am in the Detroit area and would be willing to pick up within reason. Please PM me if you have one available, or know of one that is for sale. Thanks!
