DescriptionThe whole story▼

A Bonneville T100 is at home in town: slim enough to thread through traffic, relaxed at low speed, and good-looking parked outside the office. Commuting also means the clutch is in constant use, from the first set of lights to the last roundabout, and by Friday the left hand knows it. The Accossato ESC777 is a CNC-machined clutch lever for the 2005 to 2015 Bonneville T100 with an adjustable distance to the grip, so you can set the friction point where holding and releasing it costs the least effort.

Key Features

  • Clutch lever for the Bonneville T100, 2005 to 2015
  • Listed for the 900 T100 and the 900 T100 EFI
  • Fits the original clutch mounting
  • Adjustable reach
  • Long blade for a lighter pull, in blue, gold, green or orange
  • Machined aluminium, anodised, black hub
  • Fixed blade, no hinge

Construction and Material Quality

Accossato produces the ESC777 by machining aluminium on CNC equipment and anodising the result. The two-tone finish is the same on every Accossato lever of this type: a black hub, and a blade in black, red, silver, gold, blue, orange or green. The hub holds the pivot and the adjuster, and the blade is a single rigid piece with no joint. In traffic that matters, because you pull the clutch dozens of times an hour and want it to take up at exactly the same point each time.

Stop, Start, Repeat

Stop-and-go traffic is where clutch ergonomics show. At every red light you either hold the lever in or select neutral, and when the queue creeps forward you ride the friction point for metres at a time. If the blade sits too far away, each of those moments involves a small stretch, and they add up over a commute. Setting the ESC777 closer to the grip shortens the movement and lets the hand work from a relaxed position. Blade length changes the effort as well. With the long version, the fingers pull further from the pivot, so the lever needs less force, a real benefit in slow queues; it comes in green, blue, orange and gold. The standard blade, approximately 138 mm, matches the feel of the original lever and is made in every colour. For a T100 that doubles as a daily commuter, those two choices usually make the biggest difference.

Fitment and Compatibility

According to Accossato, the ESC777 fits the Bonneville T100 from 2005 to 2015, covering the 900 T100 and the 900 T100 EFI. A second Accossato clutch lever, the EST333, is listed for the 900 T100 from 2006 to 2015, so check the product photos of both against your original lever before choosing. The front brake lever for the T100 is the EDF014, listed for 2006 to 2015 and 2021 to 2024. The ESC777 replaces the stock lever at the original clutch mounting.

Road Approval

For the ESC777 there is no German ABE on record, and it is therefore sold only for use on the track.

Scope of Delivery

The ESC777 arrives as a single clutch lever in a dedicated Accossato box.
