"Hello,
I had the opportunity to compare both models today and would like to share my experiences with you.
One thing first:
This is not a test report!
As I understand it, this contains the correct and calibrated measurement of driving performance and other data, it merely reflects what I experienced and "felt".
It is therefore still a matter of subjective impressions based on the experience of 12 years of driving the GTS and almost 300,000 km - so there is no guarantee! (before the "forum block watchers" start complaining again)
So today I was able to compare both models in almost the same condition, the only difference was the mileage of the two models.
Model 1: GTS 300HPE RST "Supersport", model 2023, with 698 km mileage
Model 2: GTS 310HPE "Supersport", model year 2025 with 184 km mileage
Both models in standard delivery condition, no changes to variator, engine, software or exhaust,
both models with original Vespa Cruiser windshield, without luggage rack, top case or other accessories!
Procedure:
I deliberately used a standard 300 as a comparison and not my own vehicle!
My 23 GTS has undergone too many "changes" to be able to make a reasonable comparison.
The first difference is immediately noticeable when starting the engine. The 310 starts almost immediately, without the starter motor even turning once.
At idle (both GTSs in cold (24°C outside temperature) condition), however, there are virtually no noticeable differences, the revs feel marginally lower on the 310 and there is virtually no noise from the variator.
When setting off and accelerating gently, there is no noticeable difference at first, but here too the 310 feels less "strained".
There are no differences on the suspension side because there are no changes, so I'll leave this area out of the equation.
Now we come to the really noticeable differences:
When accelerating fully from a standstill, the 310 remains audibly quieter, and the "hesitation second" that we know from all standard GTSs is almost imperceptible.
On the other hand, the 310 feels much more powerful when accelerating. I then asked the salesman that we drive a "drag race" side by side with both models up to 50km/h, 80km/h and 100km/h to have a direct comparison.
We are both in the weight class between 90 and 100kg on the road, so it's quite comparable...
Result:
the 310 takes almost a Vespa length off the 300 on the sprint to 50km/h, up to 80km/h it's one and a half and up to 100km/h almost 3 Vespa lengths difference.
Now the whole thing in comparison 50km/h to 100km/h and 80km/h to 120km/h
Here, the 310 outpaces the 300 by several lengths. The difference from 80km/h to 120km/h is particularly striking, with almost 50m in between.
I find it particularly impressive how the 310 converts throttle input into instant propulsion. I always had the impression that I was riding with a slipping belt on the 300 (which of course isn't true, but it feels like it).
Both tests were of course repeated with different riders to compensate for any weight differences between the riders.
All km/h values given are speedometer values and not GPS based!
I then drove onto the highway to do the top speed comparison. Although both engines don't have much mileage, the difference was clearly noticeable.
The 310 reaches the speed limiter (which is still there) at 140km/h much more relaxed and also feels a lot faster than the 300, but remains significantly quieter in comparison (as far as can be judged by the wind noise)
The 310 has hardly any noticeable vibrations over the entire speed range even when the power is fully utilized and after reaching operating temperature, I often thought to myself when the 310 was stationary: Is it still running at all?
Of course, you have to get used to the vacuum cleaner sound (especially if you ride an open Remus RS 2.0 every day), but that's the norm at the moment and to be more honest, it's not a problem.
Based on my modest impressions after this comparison, it is quite clear to me that the 310 can do everything in a bit and some things (traction and smoothness) much better than the 300.
The surcharge has remained moderate and nothing has changed on the chassis and bodywork side anyway. The now finally (matt) black switch elements make a high-quality impression, are easy to operate and fit in very well with the "Supersport" look.
You can argue about stickers in general and on the Vespa in particular, personally I would remove them, as I did on my current one.
I still think it's a shame that there are still no standard black brake levers, lettering or Vario covers (the covers on the current GTV don't fit on the 310, of course) on the "Supersport", but the accessories trade has to live, too.
So do you urgently need to upgrade to a 310 if you ride a 300 HPE RST?
Quite clearly: No!
Do you want the 310 once you've ridden it?
Clearly: YES!
For me personally, this means that I will replace my current one after two years and not after 3 years in the spring, namely with a blue "Supersport".
Let's see how far the software and exhaust experts have come by then, I didn't get the impression that the 310 has already reached the end in terms of performance if you free it from a few (currently necessary) restrictions.
In this sense:
Happy Vespazieren...
