Wrenches

Is the oil filter too tight to loosen by hand, or do the spark plugs need tightening to the correct torque? In this category we bring together wrenches for those who do their own servicing – from torque wrenches to spark plug, oil filter and steering head bearing wrenches.

How to choose a torque wrench

A torque wrench ensures that bolts are tightened to the torque specified by the manufacturer. Too loose can lead to loose parts, and too tight can damage threads or gaskets. For example, we carry BikeMaster micrometer-adjustable torque wrenches in both 1/2 and 3/8 inch. The choice depends on two things: the size of the square drive, which must fit your sockets, and the torque range, which must cover the values you typically work with. Check the range for the specific part number before you buy. After use, it is often recommended to set the scale to its lowest value so the spring is not left under tension.

Spark plug and oil filter wrenches

The 13/16 inch spark plug wrenches are available in a standard profile with a 6-point socket and a low profile with a 12-point socket. The low profile can give more clearance where space around the spark plug is tight. A 6-point typically grips more of the flats and can reduce the risk of rounding off the hex. Oil filter wrenches must match the diameter of the filter. For example, we have wrenches for 74/76 mm, a 76 mm version for Ducati and a 2-way wrench for 63 and 102 mm. Measure the filter or check its specification.

Compact wrenches and special wrenches

For the toolbag, there is a compact double-ended wrench with a 27 mm 6-point and a 17 mm 12-point, as well as a T27 Torx key with a sliding T-handle. The steering head bearing wrench adjusts from 25 to 75 mm. If you need tools for more specific jobs, take a look at specialty tools or the full category of hand tools and other tools.

Frequently asked questions

Should I choose a 1/2 or 3/8 inch torque wrench?

It depends on the torque range and your sockets. Check the torque range for the specific part number and compare it with the values in the workshop manual that you use most often. The square drive must fit your sockets, otherwise you will need an adapter.

What is the difference between a 6-point and a 12-point spark plug wrench?

A 6-point typically grips more flats and can reduce the risk of rounding off the spark plug's hex. A 12-point can be fitted at more angles, which can be an advantage in tight spaces. The choice depends on access to the spark plug.

How do I find the right oil filter wrench?

Measure the oil filter's diameter or find it in the filter's specification, and choose a wrench of the same size, e.g. 74/76 mm or 63/102 mm. If the wrench does not fit precisely, it can slip and damage the filter housing.
