NSR150R vs Aprilia RS125

Fri Jan 13, 2012 1:18 pm » Post: #1 » Download Post

So I thought that I'd write a few lines about the NSR compared to the Aprilia.

It was late the other evening and both Paul and I were getting a little peckish, so decided to head off for soup and crumpets.

I grabbed the NSR150R keys..... Wink

So, the restaurant is about 15kms away from our place, which should give us a bit of time to get some comparisons. But as I'm about 25kgs lighter than Paul I knew it was gonna be a walkover.

First traffic lights a couple of klicks away from the office and the 19 year old Honda left the 2008 Italian pretender trailing in a cloud of stinky two stroke smoke......too easy!

Hooning along at about 150kmh (Indicated), with Paul at the sharp end I dropped back a tad, stuck my chin on the tank and nailed it for all it was worth. That little buzz box passed Paul at 185kmh on the clock with the tacho buried in the red. Hmmmmm......way too short gearing.

Arrived......ate......time for a re-match.

We swapped keys, and although I knew that the NSR was obviously making way more mojo than the RS I was hopeful that my slighter frame and tuck in technique may help to stay with him.

Not so Confused The NSR just hurtled away from a standstill, and even though the Aprilia has a real sweet engine and sounds great, it couldn't hold a candle to the Jap motor.

Then came my chance. Paul was getting held up in a bit of traffic, so I did a death move up the inside on the hard shoulder. But he's a crafty old fox and knows my game, so he took to the other hard shoulder and pinned that bad boy.

He'd got a bit of a jump, so I swung across the road and hooked into his slip-stream. But, even though the RS was screaming for mercy, and well into the silly zone I just couldn't hang with the NSR. And Paul effortlessly disappeared into the distance.

My final chance came at the U-turn. The anchors on the Aprilia are way better than the budget brakes on the Honda, but although I gained about 50m, I just couldn't make the pass.......not with oncoming traffic anyway.

So what do I think?

The Aprilia is so much more refined than the NSR, but then it should be, what with being in production for nigh on 20 years. If it wasn't then there'd be questions asked. Here's why:

The Aprilia riding position is a lot more comfy and more ergonomically correct, and even when in tuck, it just feels better....RS 1 - 0 NSR

The Aprilia engine is a peach, but needs more power. This could've been a number of things as I'm no expert on the Aprilia (restricted CDI perhaps?), but we also have an Aprilia Challenge bike which is definitely faster, but doesn't have light etc so stayed indoors. The NSR150 on the other hand is a bit of a clunker down low (as they all are), and feels very raw and hard edged on the pipe. But I kinda like that. Plus it sails round happily to 12k in every gear, so the NSR wins this round.... RS 1 - 1 NSR

I like the look of the Honda. Classic 90's 2 stroke. Faaaaantastic. Blah blah blah. The Aprilia is trying to look like a 4 stroke. Nuff said.... RS1 - 2 NSR

Both bikes handle well. The old NSR would have been an old kipper if we had not changed the suspension to that of the CBR150 and given it some more radical geometry. But, I honestly think that if my life depended on it, and the roads were slow and twisty, then I'd probably hop on the Aprilia. RS 2 - 2 NSR

Braking should be included here as that's what keeps you alive. The Aprilia brakes...err...brake, and do it very well, the Honda brakes don't. RS 3 - 2 NSR

So there you have it. An in depth (not) evaluation of a couple of tiddler two strokes. And a walk away victory for the NSR!

Oh, hang on. The Aprilia has it 3 - 2........

And for a bonus 10 points, which one would I grab the keys to if I walked out the door now? Yep, the Honda. Every time.

Final (unbiased) result: RS 3 - 12 NSR. As I said...a walk away victory Very Happy

I got my 2009 Aprilia RS to 34.6 horses with a 154cc big bore kit, zeeltronic CDI, 34mm flatslide, pod filter, Jolly Moto Corsa pipe and corret jetting. I had it setup by the Aprilia race team in Dubai so I cheated a bit but it went like a rocket...I wish I never sold it as I spent a fortune on it...it also had brembo m/c. Marzocchi forks, Ohlins rear shock and many other bits.

Sounded lovely Smile Here's a clip...

EDIT - Wasn't 37hp, was 34.6 Embarassed

Might not be so keen to take the NSR if I had your bike.

Sounded as sweet as a nut Joe, lucky no one walked of with your camera while you was hooning about.

Always loved the RS since I bought a Chesterfield rep in 97, that was a beauty but I wrote it off and half my body and gave up riding unitl 2009...when I bought another RS just for the memories really.

My mate had a foxeye NSR125 and I loved that and always had a soft spot for the 150 but never saw them in the UK when I was there and interested in small cc bikes.

I think a 154 big bore kit RS against an NSR150 would be a good challenge.

RS just needs a de-restricted CDI to get the best out of. Take the NSR to the drag strip and a 14.8 will be your target.
Aprilia is aproky for a 125 (130kgs) the NSR has woeful running gear.

Top marks to matey on the country road. Shame about his "starts" Wink

A 14.8? If I went to the drag strip and raced against the chicken chasers there I'd have to walk away with my tail between my knees if I couldn't do better than that. These Thai boys are going under 11's on their 160cc two strokes and they're under 12's on the 160cc fourstrokes.

The engines are pulled apart and rolled around in the gravel, thrown back together with worn spanners and a big hammer and still they go fast......Amazing Thailand!

Seen it with my own eyes... I think the roadside sand is included in the rebuild for fast break-in times! Laughing

Good write up Matt, I must say saw lots of 135/150cc moped things in SE Asia, mostly single 4 strokes...why don't they sell them here??? They looked really smart.

Try riding your bog stock NSR150(except for a TYGA pipe) 160km to the drag strip 120km at 110-120kmph the rest through bumper to bumper traffic(no lane splitting either), flogging it at the strip and ride it home again ,then to work the next day Laughing . The Aprilia is a 130kg 125cc not a 160cc step through.

Thai superbikes/kickboxing is pretty exciting.

Ride the 150 160km? Not on your nelly! I'm not into touring. A quick 30km blast to "The Camel" for dinner and back again is about as much as I can cope with.

As for step thru's.....when you've witnesses a Yamaha Mio scooter, with a 380cc big bore kit go through the 1/4 mile at 11.9 you have to just scratch your head and walk away.

I haven't ridden a TZR125 since I raced one in Ministocks in 1991. That little demon had 33hp at the sprocket. A rip snorting little buzzbox with a variable volume expansion chamber, and a 'walkman' datalogger. How cool was that? My man was a crazy Czech genius and made all sorts of wacky stuff.

Funnily enough, there was only a couple of people racing the Honda, but they couldn't stay with the Yamaha. And the RG125 was a bit of a joke.

The poor old Cagiva got banned 'cos they had 7 gears and the Aprilia125 was in it's infancy and although full of Mediterranean promise, it didn't deliver.

As for all the bikes in SE Asia. There's some nice tackle. When I first came here in '93 I was shocked to see the Yamaha VR150R, which was like a morphed TZR on acid. Me and my mate Lee had both raced TZR's in Ministocks and we couldn't get over how cool it was. And the Krappasaki KR150 would hit a genuine 160kmh straight out the showroom.

I think the reason that the rest of the world didn't get the Asia spec bikes is because the various Governments in the developed world looked at the death toll on the Sukhumvit road and realised that selling these bikes to your average 17 year old was almost genocide! Yep, I used to spend many a moonlit night sitting on a stack of dumped concrete blocks watching the Saturday night drag racing from U-turn to U-turn. Spectacular. Also got caught up in it one night. There I was minding my own business on the Honda Dream 100. Flat out at about 80kmh when all of a sudden I was engulfed by about 50 strokers all at full noise. Very scary, but a good laugh.

That 33 was at the sprocket not the wheel.
I used a motoplat too. That was the weapon of choice for most.
It was a peaky monster with the Tony Smith pipe but the vari-vol pipe boosted the upper midrange a huge amount. The belly length had a 70mm range of movement, controlled by a windscreen wiper motor off a bus
