Bobber build advice

Hello
Hope this thread finds everyone doing well. I am an AH64D helicopter pilot currently in Afghanistan. My home station is in Germany. I recently ordered a Harley but will be cancelling my order for various reasons. I have always liked the Triumph bobbers and have decided to try and build one. Yes I am an amateur but from what I have been reading up on them it doesn't look to difficult. I am looking for advice on what would be the best type of bike to start with for building my own. There seems to be alot of older Triumphs around Germany. I have currently been looking at older model Bonnevilles. Any help in this matter would be greatly appreciated. I should be home by August and it would be a great winter project. Thanks in advance for all of your help.

Vr,
Chris

aHh, to be in a place where old Triumph's are plentifull.

Any Triumph can be bobbed. However, the pre OIF bikes (UP to 1970 for 650's)
(1974 for 500's)
would be a bit less...labor intensive. The rear sub-frame is
bolted on, not welded. Don't be afraid to look into the TR6R's
or the T100's. There's alot to be said about a single carb. And the
500cc bikes will keep up with the 650's, till you approch top end anyway.

Then you could go here for all the odds and ends-

Wish I owned this! But I don't. It began life as a 66 TR6R. Built by Choppahead, Boston.

Thanks

Thanks for the info. I know alot of people on here are against chopping them up. That wasn't my plan though. I have already been looking at the bolt on hardtails. I have the website with all of the manuals and also ordered a couple of books
1."Triumph 650 and 750 2-Valve Twins Owners Workshop Manual, No. 122: '63-'83"
2. "Building Budget Brits: A Practical Guide for Refurbishing BSA and Triumph Unit Twins (Tech Series)"
I have also went to the website that you referred to. Being new to the triumph build I am not sure what all is required for the bolt on frames. I dont know what extension 4"/6" or what drop would look good. Actuallly I don't know even know what the benefits or disadvantages of the drops are. I wanted to try and get a 650 engine if possible. I would also like to put the mini apes on the bobber..are there any considerations frame wise for this? I really like the look of the one you posted. That is a nice ride. At the moment I am leaning towards the all black with a touch of red. I am also a maintenance test pilot for the Apache...we use an IETM.which is basically an electronic manual. Reading some of the manuals I downloaded they all look pretty simple and self explanatory similar to what we use. Thanks again.

VR,
Chris

I personally, have zero tolerance for apes. Mini or otherwise. Is that
so wrong.
You should find the bike first. Before any decisions are made.
Folks can be more helpful when you have a specific bike to work from.

Shrugger,
I know alot of people that don't like apes..not a big deal..you get whatever you like. I will definitely keep updating the page once I get the bike. The problem is I am currently in Afghanistan so I am just having to browse for ideas before I get home. I have a Harley back in the states already I can ride but this is something I have always wanted to do. Since I live in Germany it seems there are alot of Triumphs available. I really appreciate anyones help or advice that can be given. Like I said before this will be my first attempt at building a bike so I will definitely need lots of coaching. Thanks again.

GrandPaulz,
I really appreciate your help. Another issue I have to check on is the registration process for USAEUR in Germany. The military can be kind of a pain in the ass when it comes to registering vehicles. Once I find out the rules I might have to hit you up on that offer. I leave Afghanistan for R and R in May and will do more investigating. I will have to check on the rules for registering custom vehicles..not sure if its the same as it is in the states with the frame number and motor information. There are quite a few Triumphs for sale in Germany..alot of really old ones ..ie BDG 250..3t 350..etc. I think my best bet would be to find a 60's or early 70's model bonneville with an operational engine for my for first build. What do you think?

A runner is prefered. Inexpensive also. The TR6R and T120 are basically
the same bike. Number of carbs being the main differance. One carb
is easier to tune than two. However, you find a reasonably priced
Bonnie. Then go for it.
Most folks are cool with bobbers. They only get upset when restored
matching number bikes are done that way. Like the guy that spent
$8k on a restored rider then chopped it. Now that goes against the
laws of nature. Don't think he's been seen alive since.

Not sure where I found this. It's a seriously sweet Bitsa I think.

Another question...like I said ..I don't know a whole lot about Triumphs. When you rebuild a TR100 can you still get the great sound that a TR120 has. Just wondering how big of a difference the sound is with the 500 and 650?

Not that much differance. You'd have to run them side by side to tell.
