How did you get on during your CBT?
After you've been trained and tested on a 595cc+ 40kW+ bike, I think it's unlikely that you'll settle for something with 10-20hp and a small handful of torques.
CBT, training, tests and licence first, then think about bikes.
I now hand you over for your ritual Teffing, which will say much the same as the above in 8,000 words. ____________________ Biking is 1/20th as dangerous as horse riding.

No, it does NOT make more sense to start effing with the suspension before you 'get settled in to it'... not having ridden anything before, let alone the bike in standard form, how the heck will you have the first clue, whether what you have changed has made it better or worse, or if its just you, the way you are riding the thing.
First; Rushing is a fast way to hurt when it comes to motorbikes.... slow down, take it easy!
Next; Keep-It-Simple-Silly... ONE thing at a time.
The clasic Cafe, you suggest as inspiration, is the Triton; Norton fetherbed frame and road-holder forks for handling; Triumph bonaville, twin-carb engine for power and speed; detail to suit tast with bum-stop (plank!) saddle; large beaten aluminium petrol tank, rear-set foot-pegs, clip-on handle-bars for a crick in the neck, and almost everywhere else tbh...
GN125/250.. for a Cafe-Racer?!?!? It's a ruddy cruiser! (ish).. more accurately its a latre 70's contrived 'Factory custom' a reletively conventional commuter bike, with token cruisery features like forward set highway pegs, pull-back handlebars, short rear shocks, long front forks and a step-seat...
It IS rather like starting with a Cadilac and saying you want to turn it into a Ferarri... it's just such a step in the opposite direction, as to really not be a particularly viable place to start.
Dont stop people... they have wire wheels, which gets them all exited, and off they go to make shitting-frog riding posiution Cafe-Brat-Chop-Scramblers that feature all manner of influences of classic and custom design... and rarely achieve much but looking like you should be rat talking about the merits of Remington type writers over an Apple mac in a Starbucks! But still...
Click profile; and you will find a few links to tiddler projects that I have done; pretty much straight renovations; 'to the book'.. this keeps things simple; you aren't trying to re-invent the wheel, just follow trhe air-fix model instructions to glue tab a to flap b etc.
Now... think long and hard on this; I am a mechanical engineer; I used to earn my crust developing missile guidance systems for the militery... I do this sort of chit for fun, and have a very long record of doing projects, and completing them... which is quite rare... about 1 in 10 motorbike projects ever come close to being 'done' less pass an MOT, even less still get regularly used, as even thier creators find them unreliable and or uncomfortable, and rapidly wheel them back in the shed to fix the stuff they didn't do or did wrong or really wasn't such a great idea when they were getting all exited about 'making it a bobber!'...
Be warned... you do not, buy a junk motorbike, wheel it in the shed on Friday; order a credit card limit load of bits from a magazine or brochure or e-bay... and just wack them together over a bank-holiday week-end!
And doing one 'here and there, as and when'... sorry, but thats a plan NOT to do anything from the off.
When you start a project, you need to be pretty clear what you are about, and how you are going to do it, and disciplined to stick fairly close to your principles for the project, and THEN you need the number one ingredient, which is project momentum... you HAVE to keep it going or it stops, and that's it.. it never gets going again.
Doing a project by installement, really is a bad idea; because every time you stop... its that much harder to get it going again; especially if it isn't going well, and or doesn't feel like it's going anywhere. Which, when it comes to it, and you get down to the nitty gritty, and its all cleaning and sanding and sorting and faffing with wires, and finding the little problems, it feels like its sapping all your energy and you dont have anything to show for it, it can be very hard to carry on even if you dont stop!
Add in the stop-start load of working out where you got to last time, what you should be doing this time, sorting out and tidying up to get on with a job, and sorting out and tidying up after... you can spend a lot of time doing stuff and not making progress or getting the job shifting, and more 'drag' to momentum.
Doing a straight renovation, not being overly fancy about it, but doing it to a reasonable standard, I reckon on around 300 man hours... hands on.. thats about six or seven full working weeks, nine to five, or every weekend for a full year... not a couple of weekends and a week off work! and that's for a straight renovation, to the book, no trial and error make ity up as you go along ideas to be incorporated.
See why so many projects get started and so few finished?
So... Keep it Simple Jeep it STANDARD, at least for a first project!
You need a licence... split that out; work on that as ONE project.
You want a cafe racer... ponder that a second project... and the notion that its almost always cheaper and easier to buy a straight standard bike that needs no work doing to it, than one that needs work, more needs more work still to turn into something its not to start with.
As said the quintessential Cafe is a Triton. This is a pretty well known quantity and depsite possible variation pretty well known.
But, if you want to find out of you can live with such a beast, first start with a few months on something a little more contemprary that is easy to ride and easy to live with. Then perhaps try living with an old Meriden Bonny, in standard form, and see how you get on with the idiocyncracies of right foot down for up gear-change and adusting cable operated twin-leading-shoe drum brakes... as well as stopping with them on old ribbed cross-ply tyres... you probably will have very different opinions of a Triton if you do... and however much you love the look... probably not have the enthusiasm to try use one for more than a garage trophy or very short outings!
And that;'s off the shelf... doing your own 'custom' project, as a learner never having done it before, not having a licence or knowing what riding a regular bike is like.... the ambition here is enormouse.
Slow down, one thing at a time, and lower the ambition and expectation levels a little.
Start JUST with getting the licence... that's enough to be getting on with. ____________________ My Webby'Tef's-tQ, loads of stuff about my bikes, my Land-Rovers, and the stuff I do with them!

Good point - thanks. Insurance is on my list to research - but I don't have costs for it yet and we're not exactly in an affluent neighbourhood. Plan is to set up a ground anchor in the front yard (standard, small London terrace) and chain it to that and I'm also looking at disc locks.
arry wrote: | Secondly - what Roger said really. Makes far more sense to have some bike experience of the recent variety and then work out what you want to do. Your view will change massively upon that. |
Yup - definitely not going to by anything until I've had some training. I get that might well completely change my game plan.
arry wrote: | Thirdly - bike wise look at Royal Enfield just because I own one and therefore it's the best worst bike there is. |
What sort of era are you talking about? Think current models would be way out of my price range and I'm not sure I want to take on the extra load of dealing with a significantly older bike - but they are just beautiful so I'm open to be swayed!

@Teflon-Mike Thanks for the best and most detailed forum welcome I've ever had - I'll do my best to pick out some key bits...

Fair point - you can't test against a benchmark if you don't have a benchmark. Noted.

I was thinking more like Honda Civic into Dodge Charger - but I see your point. Not going to quote Pinterest as an academic reference here - but seems like there are some people out there who've built some very nice looking bikes out of GN's (OK - there are also some horribly over-manicured ones). Maybe they never get ridden. Maybe they're all show and no go. I can't argue that point.
I do get the argument that 'if you want a 60's/70's bike - buy one' and to someone who might have been round the originals their whole life - me trying to turn one into the other might be somewhere between laughable and crass - I get it.
Am I ready to buy a 60's/70's bike and the responsibility that goes with that? No - I don't think so. Do I want to drop a load of cash on one of the new-school Chinese 'made to look like the real thing'. Also - definitely, no. And - for the record, I want a bike to ride - not a bike to put on Pinterest. Therefore... GN.

No experience with bikes is not no experience. Not my first time round the design and build block and a lot of what you described here - especially the 'faffing with wires' bit - is pretty much my day job. The last thing I need is a big, dumb money pit sitting in pieces under a tarp in the yard. There was no mention here of buying a 'shed find' and rebuilding it from the frame up. My attempt at a head gasket replacement on a small block V8 when I was 19 was a good quick lesson in how that can go and I've seen more than a few well-intentioned, well-funded projects fail spectacularly since then.
The good news is that I don't actually have much money to waste

I'd set your sights a bit higher in ideals than 'Honda Civic > Dodge Charger' it would be very possible/straight forward with some spare cash to waste to make a Honda Civic embarrass a 440 Hemi Charger in a straight line easily, and to make a Civic handle like one, well you'd really need to know how to fuck up a cars suspension completely to achieve that! |

I've never driven a Charger, though I did do my driving lessons in a front wheel drive Chryler with an iron six pot
My trans-atlantic summer ride of the era was a '79 Transam Six-Six, Tex-Spec sans emmissions, owned by an alcoholic oil-man who kept loosing his licence!
Chucking it about a bit along the mountain roads up in the Rockies, I DID have to seriously question the Brit opinion of Muscle-Car 'Handling'.. it wasn't that bad.. Really, no REALLY, it wasn't that bad!
It only got sort of way-wood when you unloosed the torque, and thanks to an LSD smoked both big sticky-micky's at the back, filled the window louvers with smoke, and ended up pointing in almost any direction than where you steered!
First time I opened it up; was when I had to take its alchoholic owner home; there was one of those old Volvo P things the Saint used to drive when he was Roger more? At a set of traffic lights; I was told to pull into the wrong lane along side by owner.. who then said "Err.. you need to be infront of him at the next intersection.... JUST floor eet!" I looked at the guages in the cockpit console.. looked suspiciousely at the owner, looked in the rear-view, and tried to see past the Volvo.. and not look too unbelieving "Dont worry!" He said "There's forty inches of rubber back theyur..." {Err... yeah, he was English but had spent fifteen years in the patch, most of it in texas... curiouse accent!} "It aint gonna spin up!.. TRUST ME!".... you know the Jewish for effoff?!?!?! But, I trusted him.... Volvo bogged off into the distance; I thought the thing had blown a gasket the amount of smoke in the back window, and wondered why I was pointing 45 degrees to the road, and hadn't seemed to have moved forwards.. so I backed off and the effin thing leapt fowards like a scolded cat!!! "I lied!" Said alchie owner! "Now y'know wh'ie I down hav' u liy-sance!"
And I owned a Honda Civic for half a decade..... cooking model 1.4 Auto... it did handle quite well... but?! [shrug]
Not so sure on how much it would cost to make a base model Civic get 440 Hemi 1/4 mile times.. probably less than a 440 Charger, I guess... but still. A 440 Charger would drop the quarter in under 14.... About as quick as a Type-R Civic... so they are starting pretty equal, but there aint no replacement for displacement.... and with 7.2l up-front the Hemi, is 4x ahead when it comes to chucking in lumpy cams and stuff, for any extra.
But the closer analogy here, for trying to Cafe Racer a Suzuki GN, I think would be taking a Chrysler PT Cruiser and trying to make it look like a Lotus 7!!! ____________________ My Webby'Tef's-tQ, loads of stuff about my bikes, my Land-Rovers, and the stuff I do with them!
