About BMW HP4 Race
The HP4 RACE is greater than the sum of its components. This bicycle is pure emotion. In the evolution up to the racetrack, passion is what’s made this race bicycle exactly what it is-an innovation driver made to push the bounds. The HP bicycle is the first bike in the world to offer you a completely carbon framework and carbon wheels. A handmade fantasy come true for 750 fans.
The HP4 RACE is a masterpiece of technology art. Each and each of these 750 limited-edition racing machines has been handmade by our pros and fitted with a numbered plaque. This is for all those people who don’t have any limitations and always go farther. We only create this type of concentrated fire for people who talk about it. This is earmarked for frontier crossers whose demands aren’t just fulfilled from the HP4 RACE, but need to redefine their needs. There are just a couple like this. More exactly: seven hundred and fifty.
The framework of this HP4 RACE is constructed from seamless carbon fiber and can be a constant element from the steering head to the swing arm pivot. When compared with the typical framework, it conserves nearly 9 lbs in weight. It is not all about the looks, instead, its attributes in regards to the BMW HP4 RACE’s renewable technologies. The designers eased pre-calculation and integrated function-dependent torsion and rigidity. As stiff as aluminum, as tough as steel. All benefits of the carbon substance proved completely utilized on the wheels, for example their versatility.
Perfection down to the tiniest detail
Developed for the racetrack through and through, the HP4 RACE includes a self-supporting carbon front which virtually glamorized the headwind using its competitive splitface using all the ram air behind. The dome-shaped windscreen provides riders best protection and retains them at the streamline. The ideal interplay between paintwork and carbon stuff is a highlight of this HP4 RACE, particularly when it reaches a standstill. A new age is dawning for colour also.
Constructed by hand. Configured for maximum functionality
Constructed by hand at Berlin, the HP4 RACE engine is a improved variant of this motor in the longstanding WM along with the World SBK. It generates 215 hp (158 kW) and the maximum rotational rate was raised to 14,500 rpm.
The very first provider, such as an oil change, is completed after the motor was conducted in and listed on the test stand by our experts. The motor is endoscoped and also the management valve and times clearance are corrected. Meaning the HP4 RACE is prepared to achieve its entire capacity on the racetrack directly out of shipping.
BMW HP4 Review
Few people outside the World Superbike and MotoGP paddocks have had the opportunity to ride anything quite like this. And unless you have a trendy #68k to fall to a trail bike then having a BMW HP4 RACE will stay a fantasy…
Having an extraordinary ability to weight ratio which could humiliate a World Superbike, the carbon-fibre framed BMW is much more than only a showpiece for the German marque that are intending to roll out the technology into mass manufacturing. BikeSocial was whisked to Almeria in Spain to try to tame the adrenalin-fuelled 215hp monster.
This 215 hp comes courtesy of a mill racing engine that is built by hands and also revs to 14,500 rpm (instead of 14,200 rpm on the normal engine). Intake and exhaust camshafts are fresh, as is your crankshaft (updated through boreholes from the counterweights for low weight), connecting rods, and variable-length ingestion funnels. Pistons and rods are especially selected dependent on weight, for ideal equilibrium, while BMW has enhanced bearing clearances and altered gear ratios at the brand new, close-ratio transmission (the exception being third equipment ). Peak power reaches 13,900 rpm, although the inline-four engine generates a promised 120Nm of torque at 10,000 rpm, which is really 500 rpm lower than at which a typical S1000RR makes peak torque.
The HP4 RACE’s most important framework is carbon fiber, with alloy bearing mounts and bolting points which are directly incorporated in the carbon production procedure. Weight savings? A maintained 8.8 pounds within the aluminum framework on the 2017 RR, together with all the HP4 RACE’s carbon fiber bit weighing in at only 17.2 lbs.
A back frame/seat service is constructed from carbon fiber also, but whereas the framework was assembled via a Resin Transfer Molding (RTM) process for optimal stiffness and torsional rigidity, this piece has been created through a more traditional hand lay-up procedure with chlorine.
Here, BMW has employed a”braiding” procedure, which basically means the whole material arrangement is wrapped by machine in 1 piece.
Curious about what all this implies in a wreck? Do not worry, BMW states ,”The harm chain in the brand new HP4 RACE is organised in this manner in which the carbon fiber wheels and frame would be the previous motorcycle parts to fail in case of a collapse.” Would hate to be the man to test this…
Suspension is supposed to keep you on the street, and here BMW has gone in also. Back, a Öhlins TTX 36 GP jolt operates on a more, entirely aluminum swinger–exactly the exact same arm which BMW has used on its World Superbike-spec S1000RRs.
As you may expect, all this is flexible, the final consumer (err, staff?) Having the capability to correct the swingarm elevation, steering angle, and cancel. All this through inserts which will ship alongside every HP4 RACE. Extra sprockets and chains comprised, in varying lengths and sizes.
What does not come with that? A technician guy. Then again, when you’ve got the cash to get an HP4 RACE, you have likely got the money to pay someone to check out info for you and basically do anything which does not include riding. For me personally, BMW has put up the HP4 RACE’s 2D dash up using a Mechanics manner, which looks when the bike is idling and exhibits pertinent information because of him. In riders mode (triggered when you click to original equipment ), the screen shows things such as lap time, grip control setting, search engine brake command setting, and much more. The 2D data recording method records lap times through GPS, and is intended to be utilized with additional detectors for items such as brake pressure and suspension travel, which you may add separate.
Every one of the systems may be tuned for every equipment, which means that you may, for instance, set the grip system to intervene in a specific way in the first and second gear, but be restrictive or away at higher gears. Launch controller along with also a pit lane speed limiter are conventional gear, also.
Is all this worth the approximately $87,000 price ? That is probably a matter which does not need answering, since the men and women who possess the resources for you clearly will not care, and anybody who is none of these 750 folks will only be arguing about it for the sake of recovering.
I am not suggesting that we are likely to view carbon fiber frames roll off production lines in droves, but the digital development BMW has produced here (and in the monitor ) will trickle down. Or perhaps something else which it is discovered at the very painstaking process of constructing a bicycle like the HP4 Race, will.
OK, so the primary figures for your HP4 RACE that many will probably be interested in originally are power, price and weight. And £68,000 to get a limited-edition Earth Superbike-spec track bicycle is on first response steep but divide the individual parts and the design and construction process and things begin to create sense. Particularly once you think about a set of complete factory forks could put you back £11,000 along with the electronics package, directly from WSB, includes that the ECU complete with wiring loom, dashboard and race-spec handlebar buttons is just another £7,000.
There’ll just be 750 individually-numbered bicycles on earth and 20 have been marketed in the UK… 3 into the exact same bloke. You know, one for the UK, one for Spain and another because of his inaugural mantelpiece.
