1982-83 V45 Sabre Cafe Racer

Hello everybody,
I started building a cafe racer out of a 1983 Honda VF750S (v45 Sabre) a few weeks ago. I would love to hear opinions on the progress. It is my first bike build so bare with me as I still have lots to learn.

Here is one of the designs for the final result i came up with:

Also since pictures kind of don't show the ... full picture ... i started taping my work as well. Check it out:

You have quite a project there. If it was mine, I would strip off everything, and throw it all away, except the bare frame, wheels, and engine. Good luck!

there is a guy here who did a sabre, look for his build thread and study it because what you have "rendered" is garbage. Granted it's pretty garbage, but garbage none the less.

It's pretty ballsy and slightly overconfident to entitle your video series "how to build a cafe racer" when it is quite clear you are new to this and don't really know what you are doing.

For some reason I skipped through your video and then took a quick look at the second one. Amongst other things, that broken crank case combined with the fact that odds are it needs cams and followers (for starters) means you are wasting money. By all means play with it a learn, but it would be unwise to spend any more money on it. Take it apart... see how it ticks (or why it ticks too loud) and then deposit the entire thing here in the CR.net archives of "How to build a Cafe Racer".

I like the optimism all of you have. Also glad that people caught on to the double meaning behind the titles. For those of you that watched the clips, its pretty clear from the content that the true purpose is to learn. The descriptions on the channel, playlist, and each video also do say so.

As for doing a Sabre the right way i am aware of the HackAWeek build. Have actually watched all the videos in that series. There is also these builds that I draw inspiration from:

I appreciate the heads up @Cyorg, i am well aware that the state of the engine may call for pulling the plug on the build due to cost. For now i remain optimistic as to the condition of the internals, and will carry on disassembling, cleaning, and rebuilding it.

i watched the video with the sound down, so i have no idea what you said. but it strikes me that, while you have a beard, you don't have any tatts and that may be an issue cred wise.

i see you didn't remove the tank, and i imagine, having googled "v45 sabre frame" and seen what they look like top rail wise, that once you do pull the tank your idea of fitting some other old tank will fall apart due to the frame design. most newbies don't consider this point at all it seems, and it is the problem with any of the early 80's frames that moved away from the trad design. how you're going to make the tank fit seems to me to be the thing that you will struggle with the most. unless you have the capacity to make a new tank or at least the bottom to fit your preferred top.

i did find this one, original tank? looks ok in that regard, albeit burdened with all the other typical hipster dipshit crap.

There are actually 5 videos currently in that playlist. I have taken the tank off. The current state of the bike is actually like so, with shortened forks and most things missing:

And after i chopped the frame and put the tank back on there for visual:

Why did you pull everything off a running bike to slide the fork tubes into the wrong place and hack the arse off. Was the bike certified in your name, hope so. None of the shit you posted in your dream bike collection are roadworthy in Ontario.
Did you actually think about what it would be like to ride a dipshitcycle like this

or were you to busy deciding on video lighting.

lol i didn't pull everything off just to slide the forks up and cut the tail. I am actually rebuilding everything. The forks' internals were shortened by 2", or rather shifted. Engine will get pulled out soon enough as well, taken apart, cleaned and re-assembled with new-ish components. The frame/electronics are all stripped because they will all be relocated. I am well aware that the 3 bikes i posted are more works of art than road legal motorcycles. My project will focus on the form first as well, but keep the function in mind in order to make it pass safety and get plated later on.

I do find it interesting however that there is so much hostility towards new projects on the forum. Given that cafe racers are at the end of the day custom motorcycles, that are primarily built to the liking of the builders themselves. So what looks "good" is very subjective. Either way not going to take this off topic.

Thank you for your input everybody, I appreciate any technical expertise and suggestions.

BalkanMoto, I like your attitude. Just plug along, one thing at a time. Don't be distracted by dumbasses. It's not rocket science, you'll figure it all out.

it's because we get a lot of people posting on here about how they're going to do this and that to something totally unsuited and then get all bent out of shape when they get told it's a dumb idea. even worse when their first post contains the phrase "i've been told it's a bad idea, but i think i can make it work". the people here are mostly bike industry or racer based, and so modification for form is looked on in a much less favourable light than modification for function.

and, by far the biggest issue imo, is that people come here looking for validation for their stupid ideas. i put paso wheels in my monster, because i wanted to**. i couldn't give a shit if no one else likes it, and wouldn't mind at all if they pointed that out. that's opinion and expression. it's the the internet. if you want arse kissing, do the ton tends to be far more accepting of the stupid. here, you'll get good technical advice along with ridicule and derision from people who already know how to build a cafe racer, if i may take a quote.

so, suck it up. take the good, ignore the bad, move forward and shows us something we don't know.



**(well, in truth at some point i thought it was a good idea, but the time frame between instigation and execution was so long that, once i actually started making it happen i was so far down the path of commitment that there was no point not doing it. in truth, i could have bought a nice set of oz from motowheels and bolted them straight in for what i spent making the pieces of 16" shit fit. so, continue).

as a curiosity, because i have an interest in suspension without any great knowledge, how did you do it?

i ask as i see people say they put in a spacer and cut the springs the same amount and they think there's some validity to that. i would remove the forks from the bike and compress one of them (or both for consistency) as they were on a scale and see what the maximum spring load is at full compression. then do the same thing with the spring alone (or the forks without any oil in them to negate the air spring effect) then once the forks have been shortened and you have an idea of what full compression load you need to replicate then cut the springs and set the oil height to give the desired result. i like the scientific approach.

you could also cut the top of the tube to the length you want, then thread it to accept the fork cap. After that you put in a racetech spring which is already short and use a spacer to get the proper height and pre-load.
