It’s Right There In The Name: 2006 Derbi GPR125

derbi right

Despite the lack of cc’s this could quite possibly be the closest thing to a true GP bike for the streets;  it is right there in the name, the GPR125.  Most 125cc bikes are aimed at testosterone filled teenagers but not the Derbi. In fact, the EU did not allow sales to anyone under 25 after it was discovered what was lurking under the fairing.  Derbi kept production numbers extremely low with only 125 produced a year.  SP2 versions were known to produce HP numbers close to modified Honda RS125’s and that was on pump gas!

This one happens to be on roids;  it has a 170cc big bore kit mated to a Jolly Moto exhaust.  Little known fact;  Derbi production engines are assembled by the same 4 men that built the 125 GP bikes.  It has been rumored that every now and then they would switch things up by changing things like porting, squish and ECU settings so each bike can have different performance traits.

Some of the best welds in the business.  Derbi has always been known for quality but doesn’t get recognized for it like Bimota does.  Most of Bimota’s designers came from Derbi in the late 70’s.

Did I mentioned it is titled?  Just like Rafael in Spain or Sergio in Italy, you too can terrorize the back roads on a bike that has pure GP lineage.  The BIN on her is $7,500.  Can you name a better bike for that price?  I’m still waiting for an answer.  The fact is you can’t.

1998 Derbi- GPR50 Racing E Motion

1998 Derbi GPR50 Racing E Motion

Location: Dover, DE
Mileage: 7,101
Price: $500.00 starting bid (which is mine 🙂 )

While Derbi isn’t as well known, as other scooter makers like Aprilia, these are neat little machines that can serve up a grin to even the most experienced rider.

Pretty sweet looking little machine don’t you agree? But, as with all of the machines that come out of Speedwerks I wouldn’t expect anything less.

In case you missed it, I placed the first bid on it already and I’d love to have it. This would make a great pit bike, lake bike or a learner bike and would surely bring plenty of conversation your way.

From the seller:

This bike can be registered as a moped and is ready to go! Imagine your kid on this bike learning the ropes without unleashing him on a full size bike like a busa or R1? Perfect for the stares and a grin. Fully serviced including new tires, chain, brakes, top end and reeds. All fluids, engine, coolant and brakes replaced.

The only thing that needs to be replaced, after that list, is the owner- Hopefully, it’s me 🙂

Race Replica Nirvana Part II (sort of)- ’03 Derbi GPR Malossi Replica

Location: Iowa
Mileage: 5,760
Price: $2,500 BIN

So I may get blasted for writing this up, but I can’t help myself. Yes, it’s small, yes it’s only 50 cc’s, yes it can be registered as a scooter. But, I would be happy to have it in my garage and take it out to annoy my neighbors from time to time, playing Max Biaggi around a made up circuit in the neighborhood streets. Ladies and gentlemen, what I give you here is one killer, gas saving scooter, if you want to look at it that way. Undoubtedly the best looking scooter I’m aware of.

Another shot, cause it’s just so good looking-

Here’s what the seller has to say-

Derbi Gpr 50 R Malossi Race Replica

 This is a 49cc, oil injected, two stroke, six speed.  It is in excellent condition and is equipped with a Leo Vince expansion chamber. 65mph top speed. Never layed down or crashed. Runs, Drives and Looks great.  New rear tire, new brakes and fork seals. This is the Ultimate Moped. Since it is titled as a moped your 14 year old is street legal.


More photos-

So this is not the killer Yamaha YZR 500 replica posted by Ian last week. But it is a oil-injected (no need to mix) six speed two stroke that the seller claims will do 65 mph. It also looks to be very clean and well cared for with some good maintenance.

Again, many of you may not see this as something that deserves sportbike status. But I would’t be fooled by the small engine. There’s local track near my house that would be perfect for this bike. Not a big track, but big enough that you could spend the day with a grin on your face. And then you can always blow down to the old 7-eleven for a snack on it, and turn plenty of heads.

I dig this bike. Bash away if you must. But if you see what I see, start the bidding!

2006 Derbi GPR125- Small? Maybe, but it’s big on fun-

2006 Derbi GPR125 For Sale

Location: Southern Cal
Mileage: 400 miles
Price: $6,200.00

Balas Rojas indeed- or as it translates “Red Bullet”.

I’ve always been a huge fan of small cc motorcycles and I’d say it borderlines outright jealousy towards the Europeans for me. I know we have the mighty parallel twin Ninja 250 and the recently released CBR250 single, but let’s be serious here. Are either of those really worth riding?

We’ve been long deprived of a smalll, modern, true sport bike since 1990 all the while our European counterparts get great little machines like this super looking Derbi. No, you’ll not hear me spewing about how great our entry level machines are because they fall flat with steel frames, steel swing arms and 1985 designs. Derbi builds it how it should be! Aluminum frame, aluminum swing arm, radial mounted front brake, USD forks and a trick under tail exhaust just to get the list started.

The US market stinks when it comes to entry level machines and if you are of the same opinion as me you can avoid the run of the mill ‘ho hum’ and kick it on this Balas Rojas.

From the seller:

2006 Derbi GPR125.
This bike was born from Derbis racing heritage. I bought this bike brand new in the crate and now it has just over 600 kilometers or 400 miles on it. Not even broken in yet.
These little 2 strokes came with the reliable Yamaha DT125 motors installed. This makes part access ever so easy. Has an electric start and trick under seat exhaust. Still have the nubs on the original tires.
I have done some modifications to the bike totaling thousands of dollars.
Bike has been de-restricted and re-geared. I installed a full Giannelli exhaust system. Changed out the non adjustable 28mm Keihin carburetor for a new tunable 28mm Dellorto carburetor. Removed the air box and added a filter pod. Added Boyseen reeds and removed the boast bottle which seems to never to work on this model from what I read. Took off the long and very ugly rear fender and made my own license plate and turn signal holder. Swapped out the rear turn signals. Added a trick little Daytona digital temp meter as the bike only had an over heated warning light. Not too practical.
Had all the black plastic body panels coated to look like carbon fiber. Can’t see this in the pictures but it is really stunning. Changed out many fittings to aluminum and titanium. Installed a Metrakit light weight front disk.
I have all the stock parts, pipe, carburetor, and front disk, boast bottle, air box, sprocket and a gasket set included. Have the owner manual and tool kit too.
I love riding this bike around town and down to the beach. Always a conversation piece. But it is time for this bike to go to someone else to enjoy as I just don’t have the time to ride it anymore. I have too many bikes.
I am asking $6,200 for everything. I have way more than that invested in it. Has clear Florida license and title. Tags good until April 2013.
Bike is located in Southern California.
Try to find one of these with all these tasteful modifications, licensed, titled and nearly brand new anywhere?

2005 Derbi GPR50 With Only 70 Miles In Washinton State

This is a perfect looking GPR50 with less than 100 miles since new!

Bike:  2005 Derbi GPR50

Price:  $2,987

Location:  Kirkland, Washington

Ever been to a Costco and wondered where they got the name, Kirkland, for their private-label items?  Well, Costco’s headquarters were in Kirkland, Washington from 1987 to 1996–the same city that this GPR is available in.  This GPR is available from a dealer and only features 70 miles from new.  The hi-resolution photos agree with the mileage showing a bike that looks to be brand new in every way.  Normally, small displacement bikes have low mileage because people buy them, put around on them and realize they don’t have enough power for any sense of regular use and sell them (I’ve done it).  However, this bike has only covered probably sixty miles since being sold of the showroom floor five years ago.  This bike is 100% stock and the only imperfections look to be some corrosion on the brake rotors front & rear.  There is no mention of a street legal title but I would have to assume there is one given no disclosure from the dealer.  See this cool looking piece of garage art on Craigslist here.

1999 Ducati 996 SPS In California

This is a usable 996 SPS with less than 10k miles in California!  Located in San Francisco, California is a 1999 Ducati 996 SPS with 9,800 miles.  Let’s get the big stuff out of the way first, this bike has been repainted as a Ducati Performance Paolo Casoli replica with a black powder coated frame.  The other features the seller mentions:

– Full Ohlins suspension – forks, rear shock and Damper – 5 Spoke Marchesini wheels – DP carbon fiber front fender, radiator cowl, airbox, rear chain guard and exhaust guard – Updated Yoyodyne clutch slave – Brembo billet brake and clutch master cyclinders – Brembo GP billet calipers – Full Termignoni 50mm exhaust system – Tecnosel seat – DP rear sets – DP clutch plate and clutch cover

The bike also comes with the original owner’s handbook and Ducati rear stand.  This bike isn’t original but the seller is realistic with an asking price of $9,600.  This bike has had the original Showa front suspension replaced with later Ohlin’s units.  This isn’t a bad looking bike by any means and would probably make a fantastic Homologation special that you could actually use.  See the other SPS Ducati’s we’ve posted here.  See this bike on Craigslist here.

2002 Derbi GPR race replica serie #422

2002 Derbi GPR Race Replica #422 with a scant 2395 miles on the clock.

Is there anything that makes us start salivating faster than a race replica? Okay, okay maybe a OW01, 998r or some other homologation special, but with those comes the big price tag. So what better way to be the envy of bike night than to cruise up on a mosquito killing, 49cc 2 stroke, race replica that hardly anyone knows about. And if you’re afraid of the low speeds you can always arrive early and post up before anyone else arrives. You know, sort of like “it’s better to appear slow than to fire it up and remove all doubt.” Looking fast while posting up on the cheap says a lot and you can definitely do both with this little gem.

Located in Los Angeles, CA and is .

Take a look:

Being a huge fan of small displacement bikes and Derbi’s being relatively cheap compared to most 2 strokes in the US, I can see myself owning one of these someday. Hopefully, I won’t have to “Fred Flinstone” to get it moving with my fat butt on board.

Quotes from the listing:

2002 Derbi GPR50 Race Replica street motorcycle.
Made in Spain. Only 2,395 miles. Fresh TOP-END REBUILD at 1,800 miles.
50cc 2-stroke engine(oil PRE-MIX required). 6-speed transmission. 17 inch wheels.

$600 in Performance upgrades include;
-MetraKit SP Series performance exhaust with Carbon Fiber Silencer
-24mm Mikuni TM-24 Carb upgrade with K&N Air Filter
-1/4 Turn Throttle Cable
-Carbon fiber oil pump block off
-Carbon Fiber reeds
-Nology Hotwire
-NGK V-Power Racing Spark Plug

Since it has the Metrakit upgrade that includes a carb upgrade and exhaust this one should scoot down the road quite nicely.

Price is currently at $1.499.00 with no bids and the reserve is still on. My guess is that this one will need to be around the $2,000 mark for you to be able to park it in your garage.

2004 Derbi GPR50R Street Legal In Illinois

This looks to be a very nice GPR50 in the new body-style.  Located in Chicago, Illinois is a 2004 Derbi GPR50R.  The seller, a dealer, states that this bike is street legal; giving the assumption that this is titled and shouldn’t give the new owner any problems registering it.  No mileage is listed but the asking price is $4,000.   This example looks to have low miles, be in very good condition, and have stock exhaust.  This is the first year for the latest generation GPR and looks very modern in comparison to the majority of the bikes in the U.S.  We usually see these later years only in the Aprilia guise but it’s nice to see that a Derbi has been brought in too.  See this GPR on Craigslist here.
