Featured Listing: 2005 Aprilia RS50

Update 6.17.2020: This bike has been sold for a little while but I’m behind on my updates. Congratulations to buyer and seller! -dc

In these trying times there is tremendous fear as to what might be to come. Worried about raiding your retirement account to purchase that perfect collectible specimen of a RC30 / OW01 / Mh900e that you are not likely to ride? Then how about setting your sights a little lower – as in lower seat height, lower capacity, lower investment risk and lower entry point. The only things that are not reduced with this plan are the cool factor and the fun. Today’s 2005 Aprilia RS50 is the perfect example of this “less is more” philosophy. This is an awesome little bike that allows you to channel your inner Max Biaggi and ride at 10 tenths without risking everything. It looks great and would make a fantastic addition to your man cave or garage. But please don’t miss out on riding – there is absolutely *nothing* like riding a slow bike fast. Those who have tried it would tell you about it, but they can’t stop smiling long enough to talk.

Featured Listing: 2005 Aprilia RS50

The RS50 is not your average little moped. For those raised on MB5s, AR50s and YSR50s (you know who you are), this Italian wonder is a mini GP bike on steroids. Under the full MotoGP fairing enclosing an aluminum, liquid cooled, single cylinder Motori-Minarelli engine (later units were built by Derbi), the RS offers some pretty advanced technology including a full aluminum frame, 17 inch cast wheels with a large 300mm front disk, and 40mm forks. Dry weight slips by under 200 lbs. Power – if you have to ask – hovers around 10-ish provided the tach is pointed at the 1:00 or 2:00 o’clock position. And that is where the fun lies with riding a bike such as this; nothing teaches you corner entry speed, conservation of motion, gearbox management, tachometer awareness and – perhaps most importantly – how to tuck in tight.

From the seller:
2005 RS50 with 1412 miles. Bike is all stock except for Leo Vince V6 pipe. Great condition overall except for a few minor scuffs here and there. Starts, runs, everything works as it should. New Mitas tires. New Antigravity LiON Battery. Comes with 2 keys, 1 liter of injection oil and a new Naraku 70cc BBK never fitted. Bike ready to go and is located in Cary NC

Clean & clear NC title in my name. $1900 or best offer.

The US has never truly embraced the small-bore racing set. We don’t have license restrictions like they do in Asia and Europe. American riders tend to cut their teeth on bigger bikes, and as a result they see small motorcycles as entry level. But if you can work the sliver of a power band and minimize the limitations of the format, you can scare yourself silly while having the absolute time of your life. Anybody with access to a karting track knows they need one of these. And regardless of your age/weight/displacement preference, this is something that will make you a better rider. There is simply so little room for error that by simply tooling around on this type of bike you become more focused and aware. You want to improve your skills? The line forms right here.

And the best part of today’s offering is how accessible it is for nearly everybody. I don’t know how to say it gently, so I’ll throw it out there: this bike is priced to sell. The seller is a fan of the site, and is looking to change out his current stable a bit. So if you want to become a better rider, learn skills that directly transfer to a bigger bike, feel like Rossi without ever breaking the speed limit, or simply want an uber cool piece of artwork, reach out to Roy. He is one of us and gets it. There is not a lot of power here, but this one will move quickly. Check it out, and Good Luck!!

Fast Bicycle: 2003 Derbi GPR-r 80cc

Derbis were never imported here in large numbers, but were a huge hit in Europe, and mixed it up with their Italian rivals at Aprilia in the 125cc two-stroke feeder series for MotoGP before being replaced with the 250cc four-stroke Moto3 bikes in 2014.

2003 Derbi GPR-r for sale on eBay

Though their world stage is gone, tiny, shrieking two strokes like this one continue to be the platform on which talented European kids get their first taste of road racing.

Originally a 50cc, this 2003 Derbi GPR-r now carries an 80cc big-bore kit, a bigger carb and recently-refreshed fairings, and two custom exhausts, one installed, and one that comes in a box.

From the listing:

Very nice 2003 Derbi GPR-r. I know the listing says Aprilia but ebay doesn’t know what a Derbi is evidently. Runs great and is a hoot to ride-like a really fast bicycle! Upper fairing is mismatched with one half from an 02 and one half from an 03. Runs great and is very clean. Airsal 80cc bigbore kit with OKO 24 mm carb and a Metrakit SP pipe installed by previous owner. Combination runs great! 12,500 rpm and a top speed of 71 or 73 depending on which countershaft sprocket is installed (stock and one up included). Premix only as the oil injection pump was deleted prior to my acquisition of the bike. I put the graphics on to get it as close to original as I could. New fork seals and new tires. Fresh gear oil.A few extra bits too ( drivers saddle, new rear shock, owners manual, service manual). Ask questions before you bid-no returns. I will deliver up to two hundred miles one way for free. Anything else is on you. For sale locally so auction may end at any time if there are no bids.

You lookers are missing out on a real fun ride!

The seller says the bike will do either 71 mph or 73 mph, depending on which of the included counter sprockets you choose. That’s barely fast enough to get yourself in trouble, which means you can focus on your line and body position without worrying too much about the police, or deer, or out-riding your talent.

The Buy-It-Now is just $2,000, which is a few hundred bucks less than the seller says he has tied up in the bike. Let us know what you think of this Spanish mini racer in the comments below!

A quick 50: 2000 Aprilia RS50

When it comes to two strokes, this is how the rest of the world generally sees them: smaller bikes for entry level riders and cheap transportation. Common across Asia and Europe, small-displacement bikes fall into either the scooter or the repli-racer category. Each has its own merits, although the scooter category is the most popular. Thankfully, manufacturers realize that young riders aren’t always sensible; some are motorsports enthusiasts. Thus, the small-bore repli-racers exists. And we should be happy they do. Otherwise, we might never see the likes of this 2000 Aprilia RS50 in California.

2000 Aprilia RS50 for sale in California

Utilizing a single cylinder, reed-valve inducted two stroke engine designed and built by Derbi – an uber-successful small street and race bike manufacturer, now owned by Piaggio – you can think of the RS50 as a more adult sized version of the Yamaha YSR50. Thus, in addition to its use as a young rider training tool and object of general abuse, these RS50s are also popular in mini-bike racing events. If you are an adult looking at one of these machines thinking “gee, that looks like fun” you would certainly be right. There is nothing quite like flogging a smaller, slower motorcycle to the limit. And with decent chassis and suspension components, that limit may be a bit higher than you anticipate (yet still tremendously safer than doing something similar on your Panigale R).

From the seller:
Up for sale is my 2000 Aprilia RS50. Current registration and pink slip in hand! Clear title! Runs great! I rarely ride it so it needs to go!

4,686 appx miles!
Electric start!
24mm CPW Mikuni flat slide carb
Carbon fiber reeds
Arrow full exhaust
New EBC HH front brake pads

Near new (only about 200 miles and 1 ½ years old) Pirelli Diablo dry weather racing tires. My friend spent $300 on them!

I was told by the previous owner it has a 70cc KRD kit on it. Please see the last 3 pictures of the engine with the fairings removed. It is pretty quick so I believe it (and I own several 50cc 2-stroke street bikes)!

I do not know the history of this other than I bought it from my friend about a year ago, and he only owned it for a year or two, so you are buying it as is!

With a big-bore kit, this RS50/70 should be even more fun to flog – especially around a go-kart track or similar closed course. That may be the likely history behind this bike, given the mods and Pirelli slicks that are currently fitted (although the bike retains lights, signals and license plate for street use). If you are looking for a toy to play with when the big bikes just feel too big, or if your inner child (or actual child) is crying out, this could be $2,500 well spent. Check it out here. It is certainly quite a rare model for the US, and looks like it could be a ton of fun. There are some red flags regarding history, mods and rash, but as a whole it could worth looking into. Good luck and have fun!!

Spoiled Kids: 2006 Derbi GPR125 (REPOST)

Note:  This appears to be a relist of a bike posted by Ian back in 2003. Links updated, -MG 

derbi right

Hey, everything can’t be a Mondial Piega.  Don’t frown though, if Euro teens can have fun on these why can’t we?   A dime a dozen on the other side of the Atlantic, titled street versions here are rare.

derbi left

It’s got a title and more:

I bought this bike brand new in the crate and had it shipped state side at a great expense. It has just over 760 kilometers or 500 miles on it at the time of this writing. Hardly broken it yet.

These little 2 strokes came with a reliable Yamaha DT125 motor 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 totally thousands of dollars.

Bike has been derestricted and re-geared. Removed all the emission restrictions. Installed a full Giannelli exhaust system. Changed out the non adjustable 28mm Keihin carburetor for a new tunable 28mm Dellorto carburetor. Still running a little rich for break in. Could use some fine tunning. Removed the air box and added a filter pod and Boyseen reeds. 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 to partial.

Had all the black plastic body panels coated to look like carbon fiber. Can’t see this to clear in the pictures but it is really looks stunning. Changed out many fittings to aluminum and titanium. Installed a Metrakit light weight front disk.

I have all the stock parts, pipe, carburetor, rear fender, and front disk, air box, sprocket and a gasket set included. Have the owner and shop manual, extra key and tool kit too.

I love riding this bike around town but getting too old to be racing around on a 125. This bike is always a conversation piece. I was going to install a 170cc kit. 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. Need to move on to other projects. Has clear Florida license and title, with the registration good until April 2015.

Simply put, “tiny”.

derbi close

If a Yamaha DT125 engine fits in there, would a Yamaha YZ125 engine fit?  That frame looks like it could handle a few more ponies.  I’m not so sure about the swing arm though.

The seller has a BIN of $5,000 5,800 or make an offer.

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!

derbi right back

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.

derbi arm

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.

derbi left rear

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.

Spanish Streaker! 1978 Bultaco Streaker 125

For Sale: 1978 Bultaco Streaker 125

The Spanish are a rabid lot – they love their motorcycle racing more fervently than any other nation I have witnessed. That country has also produced its fair share of racing greats: Sito Pons, Dani Pedrosa, Ángel Nieto, Jorge Lorenzo, Àlex Crivillé and Álvaro Bautista just to name a few. On the motorcycle constructor side, the Derbi models dominated small bore 50/80cc racing, and Montesa was another succesful and popular make. Adding to that legacy is the Bultaco brand, producers of sportbikes, racers and off road machinery.

The seller lists some great info on the history of the Bultaco name and brand. Let’s just say that if you are not familiar with this historic marque, I can tell you that it is NOT named after a delicious edible wrapped in a hard or soft shell (and usually filled with beans, cheese, lettuce and tomato). Cutting the story short, Bultaco was built around racing; when Montesa closed its racing division, that workforce started out on their own – and won. Even the company logo represents racing, and was based off of a rider’s hand motion to the pits: all is well.

From the seller:
You are looking at an exceptionally clean and completely original 1978 Bultaco Streaker motorcycle that has only 712 original miles on it. This is the first year that they were made and they were only made for three years. This bike starts on the first kick and runs great. It has the original blue California plates and is current until December of 2012. This extremely rare bike is in exceptional “original” – not restored condition for a 34 year motorcycle. It is very difficult to find these Streakers and even harder to find an original one. Every single part is original, including the paint.

This bike only has 10 horsepower but it will do 75 MPH – it’s is so much fun to drive and see peoples responses. When I take it out everyone says that they have never seen one before and they love it. This is the only Streaker I have ever seen in the flesh in my 40 years of being around motorcycles. They never come up for sale and those that have them – keep them and do not ride them.

I know this bike probably belongs on our sister site Classic Sport Bikes For Sale, but I just couldn’t pass it up. This 125cc two stroke is a great little bike and very rarely seen in the US. To find it in California with plates and a title only heightens the rarity. If you are into smokers that you cannot find in the States and do not see every day, this little beauty has your name on it!

This auction is on right now, and the price remains low: the current bid is only $2,325 with reserve still in place. This will never be in RC30 territory in terms of price OR speed, but it is rare and certainly has a good look to it.

Lost in the racing triangle? 1999 Aprilia RS125 in Bermuda

For Sale: 1999 Aprilia RS125

With apologies for the pun in the title (hey – it’s the weekend!), this little RS125 really looks like a fun track-day weapon – or an all-out assault on whatever local racing class will let you in. Yes, it is located in Bermuda. Do they even have a race track over there? Thanks to the fine folks over at the Bermuda Motorcycle Racing Club, I learned that the answer to the question is YES! They race at Bermuda Motorsports Park.

For the smaller or stature, this Ape is a nice alternative to the Honda 125s that are traditional fare in the smaller classes. Sure, it is not exactly right around the corner from anyone located in the U.S., but such a small package shouldn’t be THAT expensive to ship to the States… right? Any shipping experts out there ready to share some knowledge?

From the seller:
Here is a very good full race VERY FAST Aprilla RS 125 CC motorcycle for sale in very good condition, and ready to race , with Extras listed below:

3, sets extra farrings
1, tuned race power valve cylinder
2, new stock cylinders
3, race head cups
Extra rear sprockets 38 – 45
Extra front sprockets 18 – 23
Extra marchanizi race wheels wets
Extra front Brenbo break peds
Onboard computer with 3 ignition curves
Handheld computer for Curve setting
2, quick change onboard batterys
Battery Charger
Extra engine case with crank and rotary valve
Engine is in Race ready condition with all new seals and bearrings
5, new race pistons
Extra Racepipe x chamber

Back to the Bermuda connection. Check out this great video from the BMRC highlighting one of their race days. Looks like a fun small-bore motorcycle and kart track combo. Be sure and look for the foot-dragger amidst all of the 125s!

This auction is on right now and the price is relatively steep: a starting bid of $9k with reserve, and a BIN set at $15,000. Nobody ever said racing was cheap, but these Aprilias are known to be race winnners – since its debut in 1991 the RS125 (and rebranded derivatives of Gilera and Derbi) have won at least 10 championships. That is a pretty good pedigree!

For your chance to check out all the photos and info and place your own bid on this racetrack scalpel, click the link and jump over to the auction. Good Luck!!

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 🙂
