In contrast to the BTL-Line, the MX-Line is not equipped with an anti-hopping mechanism.
This SuterClutch is highly impressive through its fine responsiveness, the efficient inner lubrication, and its easy installation. The unique colour of this clutch results from the hard anodized Teflon coating which considerably minimizes the wear on the friction surfaces.
Through its ingenious design, this clutch can be fitted without any special installation tools. The pressure plate is installed using 6 bolts, allowing easy access for maintenance.
・Best control under braking
・Easiest Installation – Special tools for installation no longer needed
The Clutch can be adjusted for every riding style; for tuned models, there is a range of harder main springs available to order. Included with delivery are all the relevant parts for installation.
In MX Sports, the clutch is a vital tool for the riders to control the bike.
Not only for starting performance - the clutch is used all around the track to control the bike over bumps, into corners, out of corners, at takeoff for jumps and also as a kind of traction control.
Some riders use the clutch more than others and also in a different way. Especially top-level riders, prefer different characteristics.
Some like a very aggressive behavior, some like a softer engagement.
The great benefit of the MX-Line Clutch: Lightening quick starts and fully adjustable to suit the rider’s preference.
The standard clutches on MX bikes often run at their limit. They have a certain slip, designed to make the gearbox more durable.
Therefore, during hard acceleration, the clutch slips very slightly during each engine combustion torque peak.
In top-level racing, the need for long durability of the gearbox parts are secondary to the improved performance.
A clutch perfectly tuned to the rider’s technique is much more important.
BTL-Line: the well-established and reliable anti-hopping mechanism
The BTL-Line SuterClutch offers, as well as the normal clutch function, a so-called back-torque limiter.
Simply explained, the clutch has a mechanism internally, that only allows a specified engine brake torque to the rear wheel from the crankshaft.
Mainly on road racing, such slipper clutches are the only way to control the engine brake momentum of high compression four-stroke engines.
In the past, the two-stroke engines didn’t create much engine brake. Therefore, BTL clutches weren`t necessary.
Now that Suter has invented a fully adjustable BTL system, the riders can adjust the engine brake as they wish.
In other words, you can adjust your four-stroke bike to behave like a two-stroke - without any engine brake, or something in between.
Improved oil flow through the plate package also increases the durability of the plates and gives some extra smoothness.
Benefits of the BTL Clutch in MX
A BTL Clutch on a MX Bike makes the bike smoother into corners, especially the “kicking” on brake bumps can be smoothed out, and the bike is less nervous in corners.
The Suter BTL system works completely independent from the normal clutch function.
You can adjust your corner entry behavior separately from the "normal" clutch performance for starting or exiting corners.
Numerous testing with top riders showed improved lap times with a lower heart rate.
The riders were less busy keeping the bike on the right line into the corners or felt less kicking from the throttle.
