Can I get in­surance on a rental bike bond? Q What’s the dif­fer­ence be­tween power and torque? Q

Motorcycle News (UK) - - Garage -

I am hir­ing a Har­ley for a two-week tour of New Zealand and I have to de­posit NZ$3000 (ap­prox £1500) as a bond, which seems to be the go­ing rate. Can you ad­vise me of any­one who would in­sure this bond? John Toole, Rushock

An­swered by Alas­tair Mcfar­lane, Mci Tours You are quite right that a bond of $3000 is typ­i­cal for the type of bike you wish to hire and re­flects the cost of re­place­ment parts and time spent off the road if you bin it.

I do not know of any in­surer who will take on this type of risk. At around $2 to the pound it works out at just un­der £1500, which is ex­pen­sive, but that is the go­ing rate.

Make sure you check the tyres when you ar­rive as the wear on as­phalt in NZ is very ag­gres­sive. I took a Pan-euro­pean for our tour of the North and South Is­land and it did barely 3600 miles on a brand new rear tyre. When in New Zealand spend most if not all of your time on the South Is­land. It’s beau­ti­ful and you will want to live there. Torque is of­ten wrongly thought of as a mea­sure of en­gine per­for­mance at low rpm. Big V-twins have ‘lots of low-down torque’, and in­line four sports­bikes ‘lots of top-end power’, as if the two are dis­crete and op­po­site. They are dif­fer­ent, but not op­po­sites. Torque is the pri­mary mea­sure­ment; power is cal­cu­lated from it. Think of it like this: torque is the size of an en­gine’s punch, power is how fast it can throw it. They’re not exclusive.

Torque is a force mak­ing an ob­ject turn around a cen­tre, such as twirling a span­ner, turn­ing a door knob or, in our case, pistons and
