MotoCreations Boom Tubes exhaust for the S4RS

[El Matador]

{note: hopefully this doesn't sound too commerical -- it isn't meant to be}

I'm still surprised by the response of BoomTubes by enthusiasts. Originally they were created for my DesmoDevil bike to retain cornering clearances and to visually keep the rear tire open as I'd have hated to hide it.  Thanks to enthusiasts, I've now handmade dozens over the past four years for friends or customer bikes.  Mostly all have been a variation of the original straightpipe iteration with baffles (aftermarket or of my own design). Unfortunately I haven't had the time with everything else happening at MotoCreations (DesmoDevil deliveries in particular) to produce more or jig for manufacturing production.  Until now that is.

With the move to outside of Tacoma, WA -- I've finally had the time to move a LARGE number of parts I've designed / prototyped and tested the past few years.  BoomTubes being the first most will see. (unless you see someone doing durability testing of other upcoming parts)  The past few months, I've played with the BoomTubes design, routing, sound and visual characteristics.  Then some simulation modeling outsourced to study exhaust flows.  They are no longer just "straight pipes" as what I've done in the past. (Wait until you see the final product)  All systems will be CNC mandrel bent in stainless and CNC welded. (I hate ugly welds!)  It took three months to find the facility that would actually produce what I want to the quality control standards I absolutely require.  Currently they have the S4R, S4Rs and S4 systems for the 4-valvers and are CMM'ing, building jigs and over the next few weeks will get me back the pre-production iteration for final testing/fitment.  Then production starts for customer delivery first against the database with people who've been inquiring for months. Then they will be released to the general public.

Iterations to follow within 60-90 days after the above ship are for the 695, 620, 800, 900, HyperMotard, S2R800 and S2R1000 -- and the 696.

All bikes are dyno'd with factory system (or if already using existing aftermarket system).  System built and optimized.  Then dyno'd again.  Fuel maps as required will be done and provided also via download for "standardized" scenarios.  Will do different mapping for the different baffle scenarios available.

The interesting part of this for myself is the move from "handmade" to "manufacturing production" and retaining "quality control".  I think I've spent more time the past few months doing engineering, stuck in meetings, conference calls, visiting facilities, checking references, building e-commerce capabilities, merchant services setup, business re-org or dyno testing than in fabrication itself. (It almost reminds me of my dot.com Internet days!) Fortunately I have four years of design and prototype experience to build exactly what I want now and how I want it to sound and function.

Thanks for the responses everyone!  Admittedly this is an exciting time upcoming here at MotoCreations -- and hopefully by this Fall we will be known for more than just our wild DesmoDevil line of motorcycles (and customer Monster projects) we have built over the past few years.

That is awesome... You can expect a customer as soon as you start making ones for the 695!

Congrats on the good work and excelent quality!

Also wanted to say thanks to "c-rex" for allowing use of the S4Rs for prototyping of parts while he was recovering from wrist surgery! 

I never had looked all that closely at the S4Rs as I personally am not a fan of the 4-valver in the Monster frame. (Black Fog being the exception but heavily modified)  I've ridden enough S4's, S4R's, etc -- my opinion was reinforced.  I do though have to say that the S4Rs as per c_rex's is a fabulous bike -- that is one fabulous engine! (and suspension and brakes) Although I won't buy one for myself given what I build myself, I will find an engine / wiring and suspension / brakes and use that as a basis for an upcoming MotoCreations bike.  It really was that impressive of a bike given those components about a normal Monster.

So if someone asked my verdict today in regard to the S2R1000 -or- S4Rs?  I'd highly recommend the S4Rs now.

Mark you mentioned "Black Fog" I love that  bike and it is a huge inspiration. Will the production boomtubes be available in that exact look (the pictured prototype look angled more back) maybe i am mistaken but the set on "Black Fog" seem to come out more straight? I have an s2r 800 and can't wait to get my hands on a set. Is there any sound clip that you have i know there is a youtube video but any additional clips?

Actually the system on Black Fog is a one-off due to the swingarm setup. (note how exhaust comes out and winds back around and under swingarm and then enters outlets)  It is composed actually of 90% factory exhaust tubing from a new 996 and 996R take-off systems that were heavily heavily modified -- nothing is even remotely stock. (Tig welded and then welds polished out)  Thus Mike then has all the factory Ducati part #'s throughout the system.  I thought it would be fun and add to the "factory prototype look" of the bike we were going after.  Interestingly I've seen people write the exhaust part #'s down thinking they could go to a dealership and purchase such a system.  Hopefully nobody has tried actually ordering one from a dealer!  (note: I've had someone call with the part #'s and try to order it from myself already)

BoomTubes will be angled back 15 degrees for production systems -- @85% of everyone prefers this look.  Some of the negatives of the original BoomTube "direct out" system are: your foot gets warm when you put it down at stoplights; whomever is directly to the right of you will HATE you; reverb from walls/underpasses is a bit disconcerting for some folks.  Pros: More minimal looking; you can "blast" drivers with windows open or pedestrians while at a stop.  Angled exhausts have none of the negatives and still retain most of the fun ones too. 

Biggest perk is disctinctive looks (especially if SSS configuration), unique sound and LIGHT WEIGHT.  I'm waiting production weight figures -- but the BoomTubes on my prototype DesmoDevil only weigh 7.2lbs with baffles. (I think Nakid's system was @9.5lbs -vs- 28+ stock)  Also mass is under the engine instead of hanging out the sides or above the polar moment of the bike. (the first few miles riding them is strange as it changes the weight distribution of your Ducati a bit given the reduced rear mass)

My next bike will probably be an upgrade from my S2R 800 to a 1k. I need to get myself on your list of future customers
Do you know what will be needed in the ECU/PC/map/??/?? department. I would like an open air box and no hassles - plug and play - no new ECU, no PC, no closed loop games, maybe even no need for adjusting the A/F ratio - low fuel consumption - great sound with the CF bass - .......

I'm probably asking too much, but what can I expect?

exbox is ugly

+1.  Stylistically speaking I hope the final version of the boom tubes curve upwards a tad as opposed to just sticking straight out (horizontally). Either way they are sick!

That's how I asked him to do mine...

enjoyable scenario...

a-hole pulls up next to you at a light blasting his rick astley, looks at my bike and makes a disapproving face.

i tilt the bike to the left and give it some gas.

a-holes hair stands up as the exhaust blasts him in the face, followed by the rapid rasing of his window, and the mouthing of curses.

equally entertaining is a person yapping away on their cell phone getting the same treatment...

[Duck-Stew]

Mark did the pipes on the SS2R too BTW...  I love 'em!  Best part?!?  My customer loves them too.



Police?!?  not so much.

[Magnus]

Since we're making this a BoomTubes lovefest...

[DerekB.]

I love the look and you can put me down for a set as well!  The sound worries me though, been pulled over twice for noise and I already set off everybody's car alarm's on my street.  

Normally I don't care but if I get off at midnight or later....

[corey]

Pfff. Noise violations and speeding tickets are part of the hooligan life style my friend.

I have to admit it but I've goosed the throttle a few times when someone is sitting next to me at a light talking on the phone.

I can't imagine having a beautiful rear wheel with a singlesided swingarm setup and then hiding it all behind an ugly exhaust!  Glad to hear your customer was happy.

The craziest set of BoomTubes ever?  On Ricky's MotoCreations HyperDevil Ducati (996-style bodywork on DesmoDevil chassis) which as of this weekend is in final primer awaiting paint.  Debut this summer. (He is on the board here but just waiting until finished) The exhaust are 4-port.  Only set that will ever get built with all the twists and turns to make happen. Definitely matches the style of the bike!

I have been waiting for these for a long time....... my s4rt is begging for a set of pipes. I can't wait to see the finisshed product.  And once again  c-rex hats off to you for an outstanding work of art.
