Exhaust Chamber, Stainless Steel

The TYGA Performance Aprilia RS-125 Stainless Steel chamber, when used with a premium TYGA aluminium silencer offers huge saving in weight and combined with the VHM insert included below, it provides a very useful increase in power over the stock system. The handcrafted cones are TIG welded together to show the weld rings to maximum affect; this system is a must for the Aprilia RS-125 owner and fits all versions up to and including 2011.

Silencer, Aluminium Premium, Two Stroke, Assy.

This aluminium two stroke silencer  included in this set offers the same excellent value for money that our silencers always have but now with improved build quality and precision

• CNC machined mounting end cap with 3 holes precision drilled for mounting to exhaust chamber flange
• stainless steel exit end cap and nozzle
• cartridge glass wool insulation for greater longevity
• lightweight: weighs just 0.7kg
• tough anodised body finish for enhanced looks and weather resistance
• Silencer is designed with a built-in sealing ‘O’ ring and stainless steel bolts and washers are provided

VHM Insert Aprilia RS125 (11.50cc)

This insert has a lower volume / higher compression ratio than the VHM standard insert, meaning more low and middle range torque. This improves acceleration and gives an increased torque feeling when exiting corners. However, keep in mind that this compromises top speed.

The insert fits the OEM Aprilia RS125 cylinder head perfectly and is easy to change. It can also be used with VHM head cover AA33190

• Volume: 11.5cc
• Piston Height: 2mm
• Squish: 1.4mm

As is the case with any power upgrade, it is important that you make adjustments to the carburation as necessary. The dyno graph shown had the jetting adjusted one size leaner on the main jet and one clip richer on the needle for optimum performance. However, you will need to adjust your bike’s settings according to your ambient condition. If in doubt, start with a rich setting across the range, and lean off as required. Failure to correctly set up the carburation could result in engine damage.
