Back in the late 70s / early 80s, there was a lot of press debate on the limitations of motorcycle front ends, as they form a compromise between braking and suspension: As you hit the front brakes, the angle of rake at the front end reduces, making the bike less stable, whilst compressing and stressing the forks (remember the tank-slapper, anyone?). Yamaha referenced the various concepts and specialist bikes at that time, particularly the 1991 Bimota Tesi 1D, which used Difazio Hub-centred steering to separate braking and suspension forces. The Bimota design may in turn have been informed by the work of a small UK company called Quasar that had adopted a similar approach. In time, all these innovative solutions seemed too expensive, particularly once the advent of anti-dive systems reduced the problems inherent in standard forks. Was on the track, back in the early 80s at the same time as a race bike called Nessie that used a Difazio setup. It looked as cool as hell.
I had 2 new ones. Bought a new '93 in 95 & put 55k trouble free miles on it. I searched & found another new '93 in Dickenson ND in Jan. of '98. I bought it for $8300. right off the showroom floor. Hauled it home to Wi. & put 60k trouble free miles on it. I only wish that with all the innovative goodies on it that they would have put a single sided swingarm on back with shaft drive.
@RM - An excellent video... I had no idea. Just the eye-catching factor alone made it show-room worthy. Both it and the ZX11 were heavy bikes, so was that weight alone that made such 'front-end innovation' moot? But with all things being equal, was it better?
Yeah, they didn't sell well here at all. The salesman at DuPage Yamaha didn't want to even look at it as a possible trade-in back in 2000 when I was looking at the R1. He said he couldn't sell them when they were new, even offering it as factory discounted to something like $8k or $9k. The European models got a sport windscreen which would have been nicer. I tried getting one but it was near impossible. Also, Ohlins made a shock upgrade for it but didn't sell it in US. When I contacted some shops in GB they said they weren't allowed to ship outside of country. Stupid. Market protection isn't necessary when you don't sell that item here 🤪
Bmw's version of parallel link girder forks ala Vincent's & Britton is a much more robust, lighter & effective system.. the hub center steer devised by Elf.. meeh
In Australia these Yamaha GTS 1000 were aud $20000 in the mid 1990s and of course they flopped and l saw one for sale for aud $10000 it had deprecated by 50% is that a good investment were motorcycles of the 1970s are selling for for over aud $20000 to $30000 and in the 1970s l remember paying aud $1400 for a Suzuki GT750 no worth over aud $15000

Test rode the GTS1000 at Americade, Lake George in 1993 - Very impressive handling in the twisty roads. Also very confidence inspiring.
Good video. Thanks!
Nicely done!

In Belgium they sell only for €1700-2500
Big money in usa locally between 7500 to 10,000$$
Why was the Earl's fork not continued? No dip upon braking.
So basically a Reliant Robin A frame?
Love your work, New sub here!
I’ve just bought a GTS1000 and made a film about collecting it 400 miles from home.
Feel free to have a look
Thanks for the sub! I will definitely check it out!
Current price in Australia is 20k to 35k aus$ or $13k to $22k US

Honda NR 750 please
I will definitely add that to the list of bikes to cover!

Looks like a poor man's Tesi 1D.
