DescriptionThe whole story▼

Standard fasteners rust, and on a MONSTER 821 nothing hides them. LighTech lists the 4D8M as an engine bolt kit with 48 pieces. Ergal 7075 is the alloy LighTech uses throughout its screw kits. Anodising is what keeps the colour on an aluminium screw head.

Thirty Screws, One Colour

Anodised aluminium does not bloom white the way plated steel does. The 4D8M answers both: Ergal 7075 instead of steel, anodised rather than plated, and a kit cut to the engine covers of a MONSTER 821 rather than a box of approximate lengths. The rest is a matter of taste, and that is what the colour range is for.

Fitment

This listing covers a Ducati MONSTER 821 (2014 to 2021). The fastener pattern was unchanged across 8 model years, so one part number covers them all. We check this before the parcel leaves if you tell us the bike.

Installation

Work one screw at a time: out with the old, in with the new, and nothing gets mixed up. Work dry and clean — anodised heads mark easily under a slipping tool. We will fit it for you on request.

What Is Included

One thing about the 4D8M that is easy to miss. The scope is the hardware itself; the parts it holds stay untouched. LighTech states the kit contains 48 pieces — that is the figure for this part number, not for the range. Note the number 4D8M down; a later reorder is then unambiguous.

Supplied As

The scope of the 4D8M: 48 screws and washers for the engine. Choose from 5 anodised finishes: Black, Blue, Gold, Red, Silver. Documentation for German registration is not part of it — see below.

Paperwork

The paperwork question, briefly. No German approval document comes with the 4D8M — no ABE and no Teilegutachten. Replacing like for like does not normally raise a question, but your inspection body decides, not us.
