Steel Nitro is definitely the top of the line on
two-cycle racing clutches. This new high tech oil bath beauty is ready to launch
you into the winner's circle.
Models are available with two disc for the
Sportsman competitor who is looking for a clutch that performs great and will
require less maintenance than a dry clutch. For Yamaha Pipe and Piston Port Lite
classes a three disc version is the correct choice. For Reed Valve or Heavy
Weight classes the four disc version is preferred.
Outstanding Features:
- Small diameter and light weight enables
quicker acceleration and more revs on top end
- All billet construction for better balance,
rigidity, and durability
- Easy adjustment of stall speed without
removing clutch from engine
- A proven winner in Sprint, Speedway, and Road
Race divisions
The
HDC dry clutch is the ultimate for sportsman classes. Small diameter and
lightweight, it reduces inertia for better performance. HDC features a cam
action lever system for uniform pressure during lock up and better balance.
Features easy adjustment of the stall speed without removal of the clutch from
the engine. Components are made from the best quality billet alloys. Drums are
available in steel or aluminum.
Horstman's DXL clutches are of the oil bath
multiple disc design for two cycle racing. The DXL has been a proven winner
since 1978 when they were first introduced. Many upgrades have been made since
the originals in order to provide the racer with an economical yet high
performance clutch. Features include three discs for positive hook up and easy
adjustment of stall speed through the oil cover. Ideal for the newcomer on a
budget especially in the speedway division. For the Sr. Sportsman class and the
Yamaha KT Lite class the four spring design DXL-991 or DXL-991 3B are a good
choice. For the Yamaha Heavy class the six spring design DXL-3000 or DXL-3000 3B
are preferred.
The standard drive hub features support of the
crankshaft from the starter nut. Standard hubs are a better choice for the
beginner because mounting the clutch is easier. The extended length drive hub
(3B) features support of the crankshaft direct from the clutch hub. This way is
considered more precise, however the hub must be in perfect alignment with the
support or binding will occur.
Horstman's newest 4-cycle racing clutch named
Greased Lightning "nothing is faster than greased lightning". It was
developed from our popular MDC series clutch which has been the top clutch in
karting for many years. Designed for experienced racers that like to customize
their clutch setup to best suit engine and track conditions.
Outstanding Features:
- Designed for Stock and Superstock classes
- Light weight billet aluminum basket for lower
inertia and better heat dissipation
- Removable sprocket saves money
- 120° spaced rectangular lugs in friction
discs for better balance as well as less bind during lock up and release
- Cam action levers machined for uniform
pressure and better lock up
- Levers pivot on hardened dowel pins for less
binding
- Stall speed adjustable with spring adjustment
or bolt on weight
