Hi Sean

Sorry had to bite  :signLOL:

From the HEL website (admittedly)

Quote
We have been very fortunate to have been connected to some of the teams in Moto GP, Moto 2 and the 125cc championships but due to confidentiality agreements we are unable to list all of those on our pages. Great result for the Mark VDS Team in Moto 2 at Indianapolis with Scott Redding on the podium with third place - and with HEL Performance lines.

Inmotec - Moto GP

Mark VDS - Moto 2

Maxtra - 125cc


But anyway.....

Good catch on the teflon - im an idiot no surprise - Goodridge used to use the convoluted lines on their brake kits - HEL use the smooth bore stuff. Terminology aside

But getting back to the practicalities of brake upgrades as mentioned above if you need a 90 degree M10x1 ended hose then the only ones I can think of are of an R8 or an RS6 hose from an OEM source,  which not having the lengths published makes buying OEM at £50 per corner a bit of a gamble.......Im sure you wouldnt advocate hoses either too long or too short, on custom hoses as well its possible to specify a mid line fitting which fits into the bracketry on the upright just as the OEM GOLF hoses do increasing safety. Rather that than an OEM R8 line tie wrapped to the ABS sensor wire

So in many ways theres no other option upgrade or not

Hi Sean

We're all guilty of that!  :happy2: :grin:

Inmotec - Moto GP
WHO ????

Now they are banged to rights on 'fabricating' false claims.  Categoric proof - find Inmotec here please: http://www.motogp.com/en/teams/MotoGP

I've been a fairly avid follower of MotoGP (and 500GP) technology for many years.  There are NO braided steel lines on any 2010 MotoGP bike


Mark VDS - Moto 2

Maxtra - 125cc
OK, Moto 2, and 125GP are two very different classes of bikes to the big boys MotoGP bikes.  MotoGP are like Formula 1 on two wheels - the absolute ultimate in prototype technologies.  But 125GP, due to their diminutive power outputs, are not demanding on brakes - high corner speeds, and maintaining gained speed at all costs - is key to 125 riding style.  Moto 2 bikes basically have a standard 600cc Honda 'control' engine, with emphasis on custom chassis development - sort of going back to the old school ethos of building a bike out the back of a transit van - though granted things have moved on.

Anyway, were thrashing this issue do death.

Never been a fan of Goodridge, so cant comment on on them.  But HEL, just like BSR, along with OEM rubber hoses - are
all smooth bore.  :happy2:

I'm sure I've always agreed with you on these particular issues.  Custom hoses definately are the right way to go in these scenarios.  :happy2:




One final thing to ponder - remember the Metro 6R4 rally car?  Brakes were designed and made by AP racing (as were they on the original Metro road car) - even on the rally car, the hoses (two per front caliper, with a wierd 3 bleed nipples per caliper) were conventional rubber flexies with an external black plastic spiral reinforcement . . . .

WOW............. What a right old carry on.   :scared:

Got to love your passion TT, It certainly makes entertaining reading. :happy2:

Just for the record Inmotec are bidding to become the first Spanish manufacturer to compete in MotoGP, who originally had their racing debut pencilled in for the Catalunya Grand Prix in July before taking in a handful of other rounds over the remainder of the season. This hasn't materialised due to the ecconomic downturn, but development has continued with the plan to compete in 2011  :drinking:

Just spotted all this on the hoses and thought seen as its BSB time right now...

FYI.....

www.helperformance.com - See right hand column......Official BSB Suppliers. Our lorry is in the paddock at EVERY BSB round, and yes, Michael Rutters bike has HEL hoses on it right now at Cadwell. As does...

Byrne
Kiyonari
Jessop
Brookes
and 23 others.....

Not 100% convinced? See www.britishsuperbike.com - Pumped money into BSB for 2 years now.

Totally agree with some of your comments and appreciate what you are saying BTW, not the bit about us trying to peddle a sale though, was merely putting my point of view across, exactly as you did. Only visit this forum out of personal interest in VAG products myself being an owner of a MK5, most of my working week is consumed with all things hose related so dont get to visit that often these days.   :happy2:

Im amazed that MotoGP bikes don't have braided lines. Even my brothers Triumph street triple R had braided lines.

Not looking to open another can of worms or interested in the I know more than you debate, but not everything that was written was 100% technically correct about Moto GP hoses. Lets just say when the value of a car (F1) or bike (MotoGP) is such that it is, teams tend to produce in house (works teams particularly) or at least have a strong 'closed door' involvement in their manufacture to know exactly in their own minds the spec of each part of the kit, rather than relying on someone like ourselves to produce it first.

That said the debate for fitting Kevlar covered lines to save a few more grammes at that level over braid is valid, but not on road bikes, if its of interest here's why, taken from our HEL site - http://www.helperformance.com/info/kevlar.php
