& usage
Arrow Precision titanium connecting rods are extreme.
They are used in extreme performance situations; 'World Super Bike'
for instance, where a light drive train and very low reciprocating
weights give instant throttle response and much lower gyroscopic
forces, allowing bikes to turn in quicker. The thirty percent weight
saving over steel makes a huge difference to the reciprocating mass
of the rod and cap assembly and reduces stress loading on other
parts of the engine including the crank and bearing assemblies.
We have recently made great progress in the area of fastener retention,
probably the 'Achilles heel' of titanium rods. Where most titanium
rods use a bolt to retain the end cap, we use a stud and nut assembly,
this allows the correct stretch to be achieved without worrying
about thread gauling. Here's what John Trigger, chief engine builder
at Hawk Kawasaki said about the new retainer arrangement . . .
"I have found Arrow Precision's stud and nut retainer design
on the big-end eye to be 100 per cent superior to conventional bolt
retainers, because after 3000 racing miles there is no measurable
stretch in either the stud or rod!"
Impressive, when other benefits include ease of fitting (no special
molybdenum lubes etc.) and much greater reliability, the new Arrow
Precision Ti retaining system is a huge improvement over the old
style bolt arrangement. The Hawk Kawasaki's came first in three
rounds of the British Super Bike championships and finished in third
place with no engine failures, a great achievement for the brand
new ZX10 using Arrow Precision Rods!
If you seek extreme performance look no further than Arrow Precision.
Arrow Titanium rods are all custom made to order and are therefore
not quoted as a stock item. However we do keep low levels of stock
for the most popular applications, please contact us for more details. |
