STREET TRIPLE v STREET TRIPLE R - a brief overview.
There are three main differences: ride position, suspension, and brakes.
The ride position is subtly but significantly different. The R seat is slightly higher, and feels further forward than it actually is. The result is more of an attacking ride position: the R is more sit on , the standard sit in. For those who know their bikes, the R feels more like a Super Duke, the Standard more classic street bike - relatively speaking. However, the differing ergonomics will have little effect on actual ride since geometry remains almost identical. In other words, it will be down to which ride position suits you physically, and that is best determined by test riding.
The suspension on both bikes has been a contentious topic. In theory, the R should have the upper hand here, if only because the Daytona kit used fore and aft is more adjustable - the OE shock on the standard bike is pretty basic. All else being equal, there should be no contest, but life was made more complicated than it should have been by the initial factory settings on the R being very much on the firm side. This may have been a consequence of reports that the shock on the standard bike felt vague when ridden at speed. The R suspension is an improvement on the standard, but new owners must be prepared to work on the settings for optimum road use - it is not unknown for Rs to have different adjustment on each fork when leaving the showroom. Be prepared to use that adjustability and you will be rewarded. On both bikes, riders have commented that the front feels better than the rear, but much more so on the standard bike. The latter's suspension can be improved, on the front with re-worked internals, and on the rear by replacement............. However, the suspension you need on your bike depends very much on application. If you ride steadily on reasonable roads, you may find that the OE suspension on the standard model suffices.
As far as the brakes are concerned, there really is no contest. It isn't that the two piston sliding callipers on the standard bike are poor - especially given decent pads and proper maintenance. But the R's four pot radials are excellent, giving loads of feel and allowing the rider to confidently trail into corners. Standard is fine: but the R has an definite advantage in the anchor department.
How does all this translate in terms of performance? On one track test, the standard bike was timed fractionally faster with the same rider, but beware of a literal interpretation of that outcome. The respective state of the tyres, for example, could have been a factor. And the standard bike's ergonomics may have suited that particular rider - who knows. It should also not be forgotten that it is the R posting very respectable times on the WSBK under-card race series. But the fact remains, the gap isn't vast. The one that feels right for you is the wise choice, but as ever finances will play their part.
There was a time when the differential was a maximum of £500, depending on the deal. All other things being equal, that made the R a no brainer for many. But times change, and the gap has increased. Which means that comparatively, the R is less of a good deal than it was. Putting that to one side, most people will know which is the one after test riding, which is absolutely essential. Your call.
