Re: Aprilia SR 150 Owners Reviews and Experiences

Hi thomas. Welcome

With regards to your issue, symptoms depict three things:
1. Cone set calibration - the ball bearing array for the front shocks situated below the handle bar at the swing axle is either too tight or too lose. This prevents the steering from having "free play" and hence the gravitational central balance point is lost. The cone set needs to be replaced. And the forks too. If already replaced, they need to be calibrated. It could also be an issue with the frame array, i.e., there could be a slight bend or welding lump which hampers the above mentioned calibration.

2. Tyre pressure - inappropriate tyre pressure along with cone set and frame issues causes wobbling as balance is completely off.

3. Wheels - mag wheels have a better point of balance as conventional wheels. Hence if you hit a deep bump or similar your wheel could have developed a weak spot. Check for balancing, they will place small weight tabs for the same. Or claim a new wheel under warranty. Aprilia replaces it without any hassle.

4. Brakes - if the brake is too tight but the springs inside are loose, this causes the tire to stall and coupled with issues 1, 2 and 3, the same could aggravate. Hence get the brakes checked too.

5. Swing arm - the swing arm is your bike's knee joint. Takes most of the brunt cause of the weight of the engine and CVT unit. There's extra load on the left hand side and lack of weight on the right. Issues mentioned in points 1, 2, 3 and 4 coupled with swingarm issues could lead to Wobbling. Swingarm issues could include loose or worn out bushings, cracked rod, cracked or damaged frame or loose fitting.

6. Engine mounting - since the engine is mounted on the rear wheel, all the balance lies there. Centre of gravity is pulled behind. So if your engine is not suspended well on the frame it could also cause balance issues.

And lastly, check the entire frame. If all the above checks don't lead to any outcome, ask for a new frame under warranty. Build a good repo with the SVC and send a polite email to Aprilia India. You won't be disappointed. ☺️

Re: Aprilia SR 150 Owners Reviews and Experiences

It actually does. Since aprilia has made the pulley set lighter and reduced the size of roller weights and gearing. Hence Pickup is more peppy compared to the old SRs but lack of centrifugal weight leads to a low top speed.

Re: Aprilia SR 150 Owners Reviews and Experiences

Wego has the best balanced ride. Excellent bike for learners who are prone to falling.

Re: Aprilia SR 150 Owners Reviews and Experiences

Use the setup as 60 : 40. Aprilia has done the right thing by reducing rear braking power. It reduces load on the clutch system and also prevents locking. And to prevent locking of the front discs use a pulsing motion similar to that of an ABS system.

Re: Aprilia SR 150 Owners Reviews and Experiences

Makes sense!
I'm trying to decide between the two models as to which one would hold a higher cruising speed
The video below shows the race clearing the meter , does the standard bike have better top end than this?

Re: Aprilia SR 150 Owners Reviews and Experiences

The top speed of all SR models is the same. I.e., company claims it to be 95, the speedometer will go beyond 125 but in reality the speedometer of the SR series is calibrated to show 5 to 9 km extra. Hence it would be reasonable to say that the scoot touches 100 and redlines at 120 with constant velocity.

Coming to the difference with the two bikes, transmission and output is the same. Torque and BHP hasn't been changes, what has been is the gearing ratio to improve pickup at the cost of attaining top speed faster. So two scenarios:
1. SR 150 2016: 0-60 = Slow; 60 - 120 = Fast; Top Speed = 120.
2. SR 150 2017 Race: 0-60 = Fast; 60 - 120 = Slow; Top Speed = 120.

Mileage should vary cause since the former is always measured on economy, i.e., between 30 to 45 kmph, the 2017 race edition will burn more holes in one's pocket. But considering the slow high end speed pickup, mileage would increase on cruising. Vice versa for the SR 2016.

Re: Aprilia SR 150 Owners Reviews and Experiences

Whereas it is quicker in 0-60 by almost one second the 0-100 is exactly the same , meaning the usable range is better in the race version . Beyond 80 kmph is theoretical because the scooter was not made for the purpose . The scooter can touch 120 kmph, provided you are not riding where there is cross winds etc .

Re: Aprilia SR 150 Owners Reviews and Experiences

Folks have mentioned it perfectly well. You might be required to check your stem lock nut for excess tautness, loosen them a little bit and see how it fares. Too tight a coneset or loose a coneset would pull the vehicle to one side. Plus, if the coneset balls are damaged or unevenly seated, you might have steering pulling to one side issues.

Secondly, scooters tend to have vibrations at certain RPMs when decelerating and it can be clearly felt on the bars when one is braking from 60 or accelerating to 60 and the suddenly the throttle is closed. This is normal. If you feel the handlebar actually go left and right, means it routes back to your first issue of pulling to the right, the coneset might have been either loose or tight or worn worst case.

Rajas Sheth summed it perfectly. The bike handles like a charm, but female riders prefer one that their feet can reach the ground without tippy toeing. Also, the braking is pretty sharp on this scooter. Personally, rarely have I seen women ride this scooter much, Activas, Scooties, and Dios being their forte. I'd suggest you ask your wife to sit on the scooter, if she feels comfortable with the ergonomics, seating, if she's able to plant both her feet on the ground being seated, then a test drive should seal the deal. Oh did we forget the luggage carrying capacity, groceries, occasional whim shopping items, these scooters do come in dandy handy, but the SR, well not that much.

Cheers!

Hi Fren,

Thanks for the detailed explanation.

I seem to be one of the less fortunate. I had delivery issues - on the day of delivery the SR had lot of body scratches and did not accept delivery. The guys managed to change the parts in 2 days and then i took delivery. After 2 days of riding the SR i felt a bit of vibration on handle bar at 60+ kmph and so i let go off the handle bar. The SR leans to left and goes left without holding the handle bar. At 60+ speed a slight wobble is also seen, when i let of off handlebar.

I immediately complained to the service station and took the SR the next day to SVC. The service guys said that there was nothing wrong with it and they don't feel the wobble or leaning to left. Then spoke to the manager and he said he will ask the regional Aprilia service engineer to check.

Following week i again went to the SVC to get the SR checked by the Aprilia Service engineer. The VP of Aprilia was also present there since they had some sort of business meeting with showroom owner. As i was waiting there where at least 3 SR's which had battery issue. The battery seems to die in 2 weeks even with regular use. The SVC manager showed the SR's to the VP and said that they where receiving battery issues.

Then i explained the issue to the VP and the regional service engineer. I showed them that the rims are a bit bent and they have a wavy motion when in rotation. To this the service engineer stated that it is within the permissible level and that it wont affect the handling of the SR. Then he took a ride on my SR and confirmed that it pulls to the left. I was asked to come another day to have it sorted. In another 2 days i left the SR at SVC and from what the Service engineer told me - he retorqued the front forks and the issue was solved. But when i took a test ride the issue was still there. About the wobble - the service engineer claims that there is no wobble and in case there is an actual wobble than one will be able to feel it at a very slow speed. I told him that i will get back to him in 2 days.

As of now i have told him that the issue is still present and want him to take a look at it during the first service. Hence i want to ensure that the issues on my SR are legitimate and that where i would require the help of a fellow xBhpian SR owner in Chennai to test ride my SR and compare it to his SR.

Me @ Guindy. Sent you a PM.

Re: Aprilia SR 150 Owners Reviews and Experiences

My sr150 makes a clicking noise from the rear wheel area when I go over rough roads or acclerate from slow speeds, the svc says the rear wheel needs to be replaced.Is any one else facing such an issue ?

Re: Aprilia SR 150 Owners Reviews and Experiences

Yes yes... I faced the same problem. They replaced the rear wheel, make sure they tighten the brake pads too and get the clutch pulley system checked too.
