TZ 750
« on: November 18, 2009, 12:24:35 AM »
in the new issue of cycle world the TZ 750 was mentioned in an article, mentioned how Kenny Roberts tried to ride it, and it sounds positively brutally dangerous...........i'd love a ride on one, bet theyre not cheap to acquire or own though.

it sounds like a pissed off wasp!  Kenny Roberts on the TZ is the last 40 seconds or so i believe. they showed the modern dirt trackers for contrast to the 34 year old Suzuki.

Definately not cheap to run!!!

Rings every 4th race
pistons with every 2nd set of rings
crank every season
Crankcases every 2nd crank

Not to mention shares in NGK and trannies!!!

That's not massively different to any GP 2-stroke though is it Brian. I mean an RS250 honda has new reeds after 150 miles, new pistons after 300 miles and new crank at 1500 miles?

I guess the TZ bits will be harder to get though....

Bucky - last TZ I saw for sale recently was £13,500 GBP and it wasn't a mint example, they just go up in price from there!

I've wanted a TZ750 (in fact, one of the very few Yamaha's I'd want to own) since I first laid my eyes on one. I wonder if Alan Milyard would make me one out of two RD400's, but then again, I'd settle for his V10 Viper, Ooooher! ;D

I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Bucky, if you ever get serious about wanting a nasty, hairy, tire-eating H2 with 151 horsepower that comes on/off in 500 rpm - I have one with 42 pampered miles on it for sale. I can't ride and enjoy it, but it's begging for a new home for the person who can.......

Yes, I'm serious, the green meanie can be had for cheap - about 2/3 of what I have invested.

No, the whole reed set-up is here in boxes. The bike starts and runs perfectly, just needs someone to ride......

There was a street leagal TZ750 that I posted last year in the For Sale section that ended up selling for $12,000 CDN (around $11,000).. It came from a collector that had a bunch of great old race bikes.

Someone's got a 1000cc twin two-stroke combination type bike in the small ads of classic mechanics this month - very weird looking.

Not to mention shares in NGK and trannies!!!

   They were never that expensive to run even when I had my first one back in 1982.
    Now with modern oils and better parts available it is more like
       Rings every 500 miles
       Pistons every 1000 miles (forged pistons are now available for 750,s and last much longer than the origional yamaha ones. I have personally used these pistons for over 1400 racing miles.)
       Crank rebuild 1000 racing miles. My current cranks have done over 9000 racing miles using the same flywheels. (German made heockle flywheels.) Now being remanufactured here in the uk.
       Cases , Likewise the cases have done a similar mileage and I dont intend replacing them any time soon.
       There are approx a 12  to 15 tz 750,s (solo,s and sidecars) now being raced in the uk quite regularely and they are all using cases that are over 25 years old as there as not been any new ones available for many year. However that will change quite soon as the first batch of new cases is currently being made in france so hopefully we may see even more tz 750,s out on track next season.

I guess not but then racing any bike is not for the fainthearted among us. Just making the point that they are not as expensive to run as some would have us believe. Here,s a link to some pics of my bike for anyone interested, and by the way the bike and rider have a joint age of around  85 years  so you are definately as young as you feel!!!.  http://web.mac.com/rg500delta/iWeb/tz750-racers/Rob%20Hall%20photo%20page.html

the 750 is too dear , they sell over here for around 15 grand and unless they have a very good history [ which can be verified ] there not worth much more.
the TD!C  does look nice and original
