Well smart, admittedly not a thumper but just look at the engineering that,s gone into producing what can only be described as a work of art. Now where did I put that lottery ticket

Beautiful bit o work. I hope they can make some sort of headway with it. Recruiting a young gun might be a good tactic? Not so much to 're learn when it comes to the "feel".

It's only a Honda CBR600RR but with a price tag of £29500. Bit over priced for a Honda CBR600RR
I will still have a big cheesy grin riding my XBR

Don't those xbr thingy's use those floppy extensions which I believe are referred to as "forks"? Urgh! So passé.

Hee Hee.  ;)

Tried and tested per-say! And simple.

People have been doing that for decades, and always gave it up as a bad idea. Yamaha had one back in the '80s, for example.

Yes they did and as I recall a privateer did rather well at the TT on one, proof in one,s pudding the "conventional " does,nt always mean better. Take look at the Britten for example, one of bikings all time great giant killers and again proven on circuits and road based tracks like the TT. Such a shame he passed away at such a young age as it would have been very interesting to see how far he could have taken things with more development. I say good luck to the vyrus team. Go kick some giant ass

They did indeed and there's one on display in my local bike shop, CMC at Clay Cross in Derbyshire. I think they were called GTS 1000 but I could be wrong.

How much they want for it?

True. Can't argue with the fact that telescopic's are everywhere and there are no (mass produced) hub centres. Although bmw have done ok with the saxon mottod idea and the hossack design.

I'm not entirely convinced that the reason is because hub centre (or other ffe) doesn't fill certain technical requirements. "Feel" always seems to crop up these days in gp racing, as a reason why racers don't like designs which separate braking and steering. Then again designers of gp bikes put a lot of thinking and no little physical and financial effort into "tuning" the front end of a bike to cater for the fact that when fully cranked over the forks don't work. I'm not saying a hub centre would operate more effectively in this scenario but they might. Devices which rely on pivoting suffer less with stiction than things which slide. Besides, the wheel hung out on the end of an arm just cries out the facility for "tuning" the beam, in my eyes.

Maybe it's even simpler. In the early eighties dive was seen as a major issue, but the intrinsic limitations of telescopics in this regard have pretty much been put to bed. That and the fact that dive is no longer a dirty word. In fact we get the impression it is seen as essential by most top level gp racers.

All I can say is thank goodness there are some attempts made at alternative ideas.

Yes smithy you,re correct it was the gts1000, thanks for refreshing my memory on that one, can,t remember the guys name who did the TT but I,m sure he got a second place

I think it was Steve Linsdell - his son Ollie still races on the island.

Hi Propellor

Sadly I don't think it is for sale as they have various older yamahas on display. you never know though, they are after all a business so when I go there this weekend I will ask and let you know.

Hi smithy.

Please don't put yourself to trouble as I don't have spare funds for anything right now. It was kind of you though, so thank you. If you're going anyway then fine, no harm in asking.

Cheers.

Anyone remember the 'Quasar'! That had hub centre steering.

(http://bikeweb.com/files/images/blezquasscruteweb_5731-1326.preview.jpg)

And didn't Danny Di Fazio (?) have something to do with it at one time?

..........

I remember it. There are a few different methods of hub centre and I think maybe the quasar used the di Fazio method. Tony foale did a good article on it. I believe it is on tinterweb.

How about RON haslam and the elf honda.

I love the stellan egelland harrier. If I won the lottery that would be one bike I'd go straight out and buy. Along with a confederate fighter. In fact I like all the confederate stuff.

The front end of the egelland harrier is an "off the shelf" item from the Swedish ISR more commonly know for their brakes, worth checking out their web site for anyone who,s interested in this sort of thing, nice little vid of how it all works etc.

Hi Propellor

I know what you mean about funds! I'm popping to the bike shop anyway as they do the best breakfast for miles around and me and my mate Dave go for a feed and a natter most weekends.
