The Yamaha TDM 900 is a combination of different styles. Its parallel twin design has been on the market for over a decade, which speaks highly of the success of this model. Rider-friendly and comfortable, great for everyday riding, long trips, solo or two-up. And in addition to its great-looking design its has lots of power and torque, which promises to lower the time it takes to get you from point A to point B.
The Yamaha TDM 900 gets a double bonus – a double Akrapovic top-flight component. The SLIP-ON exhaust will give a refined elegance to the stock system. But the aesthetic factor is not all; you can definitely expect more power and torque from your engine as well.
Measurements of the Akrapovic SLIP-ON system on the Yamaha TDM 900:
Power: the Yamaha gets pumped! The excellent results we achieved with just the basic level of exhaust system tuning will amaze you. The increase over the stock power curve starts right at the beginning and just gets bigger as the bike winds up, reaching 75.8 HP at 7100 rpm. It should be added that the power transition at the top of the range is smoother than with the stock system, which means longer-lasting useable power at the high end. The max. increased power is 3.4 HP at 6700 rpm.
Torque: if you liked the look of the power curve, take a look at the Akrapovic SLIP-ON system’s torque curve! Like the power curve it is higher than the stock curve, especially at the transition to the top end, where it is quite steep and therefore offers quick response to demand. Thus both the power and torque measurements are exceptionally well suited to the style and purpose of this motorcycle. Long trips or quick cornering on country or city roads are all home territory for the TDM 900.
The Akrapovic package is truly an excellent addition to the TDM, and not only in terms of aesthetics.
As can be seen from the measurements, the performance upgrade is substantial, and in addition there is a considerable weight savings as well, amounting to 5.48 kg over the stock system.
