|Suzuki Hayabusa - Performance and other enhancements.||
2nd Gen Hayabusa
Last Updated : 29 April 2012
There are heaps of performance enhancements available for motorcycles. However like all enhancements there are some which actually work and some which don't. I receive a lot of Emails about this topic so here's a running list of sorts with various notes on the topic and those you can contact. Remember : I am not a mechanic or motorcycle engineer and cannot personally verify any of these as I haven't tried them out myself. This site is for general information purposes.
Performance improvements can be made in a
variety of ways. It depends on what so of enhancement you want to do
to your bike. In the Hayabusa's case there appears to be an increasing number
of stuff you can try.
This page is continually being updated!
Personally. I prefer Yoshimura but many choose Akrapovic because they are cheaper. I think the Yoshi's have a piercing top end. *shivers* Remember it the the skill of the tuner rather than the pipe itself!
Other exhaust pipes : The best site for information on exhausts pipes is Martin's Hayabusa Page Heaps of stuff on performance and other tech enhancements which I don't cover.
Sidekick Performance Silencers : According to them adds 6 HP. However I haven't seen where the improvements were made. The construction of these things look like a work of art. Like the use of multicoloured 0.5mm thick 99.9% pure Grade2 titanium etc... Try telling that to boys & gals next time you see them !! Their site can be accessed on the links page. You must check out the 'Alien' exhaust !
Skorpion Exhausts : Looks good and sounds even better. With thanks to *Pete Priss for the pics.
Try these suspension settings for a racier
ride. Thanks to Darrell
The most effective way to
get the best performance from your Hayabusa modifications or any other
motorcycle is the Power Commander system.
Air Filter modifications
Using BMC Air filters is another way of
increasing power without any detrimental side effects. Except for an increase in
fuel consumption of 10-15% (city ?).
K&N airfilter is another suitable replacement. Thanks to Dany
The best modification to the Hayabusa for a noticeable performance gain is to the airbox mod and filter and the Power commander . - This essentially involves enlarging the hole to the

MRA german made Sport tourer flip tinted
Chrome look ! : Stripping the paint of the wheels reveal a nice aluiminiumhrome look !
Eliminate! Eliminate! : Removing or shortening the rear fender (mub-guard thing) is another thing you could try.
Assimilate! - Colour coding the mirrors, handle-bar grips, fairing screws, engine side cover, bar ends etc... is also a nice touch.
Are you after a new colour scheme for your Busa ? - in fact as so many people have asked can they have the original Copper/Bronze colour scheme ... strange huh ?
Change the background of the speedo.
This is quite a common enhancement.
Oil and the Hayabusa
Quite a few questions about using different
types of engine oil so
Another note regarding using full
synthethic oil is that on a bike with multi-plate clutches is that it will cause the
clutch to slip especially on take-off !
Full synthetic: Silkolene PRO-4 race is supposed to be a good one to use.
Full synthetic: Mobil is another that comes recommended. Thanks G.Raiford II
Synthetic Blend i.e. Mineral & Syn : Seems to cure grabby clutches. (Motul in the brand) Thanks to M DickinsunNEW !
The following is an email that was sent to me from Lynn HolznerHaving been a lubricants distributor for the last ten years as well as an avid Motorcrosser I feel I can shed some light on the synthetic lubricant clutch controversy. I will try and keep it short and simple.
1. All lubricants whether petroleum or synthetic are engineered to meet a specific, requirement or range of requirements, i.e. two stroke, hydraulic, ATF etc.
2. Synthetic lubricants ( at least most synthetics ) are engineered from the ground up. Petroleums start with a petroleum base stock and additive packages are added to make it do its job. I like to think of it as going NASCAR racing with a street car you tried to adapt to the job rather than starting with a frame and building it to do the job. Which one will work better?
3. Regular motor oils (for non-wet clutch applications) have components in their chemistry such as robust friction modifiers that are not a wet clutches friend. If the truth be known, motorcycle owners that have used synthetic oil in their bikes and experienced clutch slippage used oil not specified for motorcycles (although you would be hard pressed to get them to admit it).
4. Synthetic motor oil spec'd for motorcycles with wet clutches are engineered with different types of additives to make them function with the clutches as well as providing optimum engine component protection.
5. The original clutch in my 1999 YZ 250 lasted almost 3 years using full synthetic motorcycle oil. I did not experience any slipping or abnormal "grabbing" throughout the life of the clutch. I extended my change intervals to at least 3 times the recommendation in my manual while my ridding buddies were changing theirs after every full day of riding.
6. It is the 21st century and oil technology has not been idle all these years. There are loads of "wives tales" out there. Mostly started by people who are resistant to change or have monetary interest in keeping people changing oil every three thousand miles and bad mouthing synthetics.
7. If you are really interested in the truth there is a book out by Michael Kaufman called the "Motor Oil Bible" which dispels all the rumors and myths about oil change intervals and synthetics vs petroleum. The book is based on information from many industry sources including SAE.
Note : Check out the pictures site for some
pretty good ideas.
Gear Indicator : See what gear your using as well as the optimum shift points.
Higher Handle Bars : At last I have some
stuff on raising the handle bars. www.helibars.com
Another firm that produces bar raises. : ww.zianet.com/genmar Thanks Wayne
Lowering the Hayabusa :
Use the Schnitz lowering bones for the rear
1- 4 inch drop
Raising the Hayabusa :
I have never heard of
anyone who actually wants to raise one..
Frame sliders :
Great addition if your
after looks especially if they are shiny or light up !
See the tyre survey link on this site !
Do you want more power ? Well try a Turbo or the simple airbox enlargement and muffler replacement.
Derestrict the Hayabusa - Speed limiter
How to bypass the top speed restriction on the Hayabusa is by the use a TRE or Timing Retard Eliminator.
I've updated this bit yet again - I though there was enough information around the web but I was wrong so here are some links and ads.
I have heard - from no less
than 3 different owners the TRE does indeed work for all year models to date.
The ECU gathers information from the gear
position and the rev meter to detect when to retard the injectors. There are
apparently simple electronic units that in effect derestrict the bike ! I've been
reliably informed that the US mag Sport Rider had an article on their experiment.
Note that replacing the ECU on a 2001 model
with a 1999 model will not work.
With the update to the new 32-bit CPU the limiter restricts the max revs in 6th gear to about 10,200 rpm or so. Note that the TRE is still effective but mapping not correct although still works fine though.
Note : I have heard a heap of good reports using the TRE.
The only side effect I have heard apart from all the good stuff is an increase in fuel consumption and some hot starting issues - to be confirmed.
A good story about the results of a the
installation of TRE.
I am still running the original exhaust system purely because I like to keep a low profile with the police! The drive from the bike now is extremely strong and I am really impressed. Steve only works on fuel injected Suzukis - he has a 'busa himself which he can tell you about if you are interested. Had a fuel injector fail on me - the second in 12 months. I have written to Suzuki and I am waiting to hear what they have to say. I hope you don't think that I am plugging Steve's work - he aint paying me! It is just that the work he has done has so impressed me that I would like other owners to have the same benefit. They wont be disappointed and it doesn't cost the earth! He can also modify bikes with other after market exhaust systems
