    Hi all, just took delivery of this 1977 TZ250D frame, bought it cos it was there with some thought so now I have options and need some advice. It looks straight with one repair to an engine mount and I'm told extra bracing on down tubes, has correct number, needs paint.
    Options as follows;

    1- Collect parts and restore as original?
    Will cost arm and leg, more than I could buy a good one for complete £8-10K

    2- Keep it as is, make a swing arm and fit a shock, just hang on to it and concentrate on getting a new workshop and van (hauler) sorted like I should be doing.

    3 Buy the RD 350 shown on Fleabay and make a road going replica. It is priced ok (just), and am considering the following
    Runs but has 250 bottom and 350 top?? Is this possible? Not that bothered.
    Wheels would look good gold and brakes look correct could use forks and maybe even steering stem.
    Fairly sure the aircooled motor bolts straight in? so no frame mods.
    Maybe use swing arm and convert to monoshock, this means all rear wheel and brake would fit.
    I could sell off the RD frame and bits to recoup a little
    I could use the TZ number to get a 1977 plate
    The TZ tank, seat, fairing are all available in good quality glass
    Must have DG pipes from stateside-need inmate help
    I might even turn a profit!!!!?????
    I need to get it done in three months...……..

    Find some flaws in my plan please, I would have to buy the RD by Monday......

    I think getting it done in 3 months would be the hard part...... at least for me...
    A TZ frame needs an engine with a dry clutch...... Just because dry clutches are cool :thumb

    As I remember air cooled rattle as much as a dry clutch anyway :D

    Boring but.....

    Workshop and van.

    Then all future builds will be so much easier/nicer/blah blah......

    You have achieved amazing things from your current garage, just imagine the future in a bespoke spacious organized workshop!

    Cheers

    The bottom end was the same with different markings on the cases, I know in NZ when I was young a 250cc bike was beginner license and easy to get so that was a fairly common 'accident' for the 250's to have.

    Reasonably reliable but - they make better power when running too lean. Be careful of that because if it feels it's running really good, it's about to seize ;). Other than that quirk they COULD run for years as road bikes without major problems.

    Slipper clutch if you can find one is a good idea, that way you don't have to ride with one hand hovering over the clutch lever when riding gets exciting.

    A kid I worked with had a 350. Got the urge to do a bit of racing, Mallory being just down the road. He was always pestering around the workshops for small (or large) jobs to be done. I made him a paddock stand and a few bits and bobs - one of which involved the front wheel. Goddamn was that thing heavy, like it was made of cast iron not aluminium. Compared to the ones on my Morini, there was no comparison. Once we got over the shock, his dad stumped up for something lighter.

    Your conundrum can be resolved by referring to the man-fish-teaching old saw.

    ps I remember the reason for playing with the front wheel - fork brace. The gyroscopic forces on that fucking millstone would have bent modern forks.

    The TZ frames were notoriously prone to cracking. Not a good choice for road use. The RD frames were very close in dimension and geometry with all the added tabs and bobbins for all the street stuff, but made of heavier material and much more robust. For a road machine the RD chassis is a better choice.

    Not as cool- just better.

    I went to see this S3 before xmas when it was on Ebay as it was only 10 miles from me. The Ebay pics looked terrible, cushions piled on top of it, snapped indicators and the rest of the pics blurry and ill judged. When I saw it the guy uncovered it and fired it up and it was just fine, it was on a trickle charger with the seat loose which made the pics look even worse. I lowballed him and didn't bid, it got no bids and he didn't take my offer.
    Anyway, it came on a week ago at the same starting bid £3K and got a bid...1 minute to go and I dropped £3100, good price in the UK, now it's mine :D:hmmmmm:loco pick it up later this week then decide what to do with this...??

    Nuclear orange! An old friend had an S3T that reportedly he put 200K plus miles on. That one looks unmolested.

    Guy at the local moto gathering here on Sunday had a new Yamaha R3 with some vintage esque body work on it and a 100+hp 480cc Yamaha RZ motor in it.

    it was fuckin fire!

    GG retro fitz.

    you should check it out.

    I saw this, done by Wicked ATV, they were the guys that I got all my 421 conversion parts from. Can't find video though.

    100%

    but 100hp 2 stroker has got to be fun in a reasonably modern chassis like that

    As an RD/RZ fanatic and former racer of both, I appreciate what you have. But to be completely honest it doesn't look a lot different from my RZ350 frame. Make it a road bike and have some fun.
