Shimano Lure Rod Model Numbers Explained

Codes such as 1610M-2, 1652R-3, and S86ML-S tell you far more than a Shimano rod's place in the lineup. Depending on the series, the model number can identify the reel type, length, power, taper, piece count, and tip construction.

The important caveat is that Shimano does not use one universal format across every rod family. A number such as 65 may describe 6 feet 6 inches in one family and 6 feet 5 inches in another. The safest method is to decode the pattern used by that series, then confirm the exact specifications for the model.

Quick reference

Part of the code	Typical meaning	Example
Initial 1 / 2	Baitcasting / spinning on numeric-leading bass and freestyle rods	1610M-2, 2652R-3
Initial B / S	Baitcasting / spinning on many saltwater rods	B96M, S86ML-S
610, 86, 84	Length in feet and inches	610 = 6 ft 10 in
UL, L, ML, M, MH, H	Power class	S86ML = medium-light
+	Intermediate power above the preceding class	L+ sits above L
FF, F, RF, R, RS, S, SS	Taper or action	R = regular
-2, -3, -5, or /2	Number of pieces	1652R-3 = three pieces
Final -S	Solid-tip model in applicable families	S86ML-S
Final -G	Glass-composite model in applicable families	Series dependent

Start with the series name, then read the reel type, length, power, taper, and piece count in that order.

1. BB, SS, XR, XTUNE, and LIMITED are grade names

Before decoding the model number itself, separate the series grade from the specification code. Shimano often uses names such as BB, SS, XR, XTUNE, and LIMITED to position products within a family.

Grade name	Shimano terminology and role
BB	Blood Brother; a series name used for models that inherit the concept and character of higher-tier products
SS	Superior Spec; a series name used for models with upgraded materials or features
XR	A higher-tier series name used across several product families
XTUNE	Extra Tune; a high-tier series name
LIMITED	A name used for flagship models in families such as Sephia

These labels do not replace the specification code. In Sephia SS S86ML-S, the first SS belongs to the series name, while the final -S belongs to the model number and identifies the tip specification. Position and punctuation prevent the two from being confused.

The order of these grades is not universal across every Shimano rod family. Hard Rocker, for example, uses the progression BB → SS → XR → XTUNE. Use the grade name to locate a model within its own family, then compare the technology and specification tables rather than assuming the same hierarchy applies to every Shimano rod.

2. Read numeric-leading bass and freestyle codes from left to right

Many Shimano bass and freestyle rods begin with a number rather than B or S. A useful pattern is:

reel type / length / power / taper / piece count

The first digit identifies baitcasting or spinning

On models such as Zodias and World Shaula:

First digit	Reel type
1	Baitcasting
2	Spinning

Therefore, 1610M-2 is a baitcasting model, while 2652R-3 is a spinning model.

The following digits describe length

In a code such as 1610M-2, remove the initial reel-type digit and read 610 as 6 feet 10 inches.

Length code	Length
60	6 ft 0 in
66	6 ft 6 in
610	6 ft 10 in
72	7 ft 2 in

There is one important series-specific exception. World Shaula and Scorpion commonly use 65 and 75 as half-foot designations: 65 means 6 feet 6 inches and 75 means 7 feet 6 inches. By contrast, an Expride 265ML uses 65 to mean 6 feet 5 inches. The same digits can therefore produce different lengths in different product families.

Do not decode the number without first identifying the series.

3. Power may use letters, numbers, or a plus sign

Shimano commonly uses familiar letter-based power classes.

Code	Power class
SUL	Super ultra-light
UL	Ultra-light
L	Light
ML	Medium-light
M	Medium
MH	Medium-heavy
H	Heavy
XH	Extra-heavy

In 1610M-2, the M indicates medium power. In S86ML-S, ML indicates medium-light power.

World Shaula and some related freestyle rods can use a numeric power class instead. In 1652R-3, the 2 is the power class and the following R is the taper. Numeric power should be compared within that family rather than treated as a direct universal substitute for M or MH.

A plus sign indicates an intermediate class

The + in S84L+ means the rod is stronger than the base L class. Shimano uses + for an intermediate setting toward the next power class, but the exact blank design and usable range remain model-specific. Read it as light-plus, then confirm the published lure or egi range.

4. FF, F, RF, R, RS, S, and SS describe taper

When a taper code is present, it describes where and how progressively the blank bends under load.

Code	Shimano wording	General character
FF	Extra fast	Bend concentrated closest to the tip
F	Fast	Tip-focused bend
RF	Regular fast	Between fast and regular
R	Regular	More progressive bend through the blank
RS	Regular slow	Deeper bend than regular
S	Slow	Broad bend through more of the blank
SS	Super slow	The deepest, most progressive bend in this sequence

The taper code comes after the power class in models such as 1652R-3: 2 is the power class, and R is regular taper. Not every Shimano family prints a taper in the model name, so the specification table remains the final reference.

5. A final -2, -3, -5, or /2 states the piece count

A hyphen followed by a number commonly identifies how many sections make up the rod:

• 1610M-2: two pieces
• 1652R-3: three pieces
• 1652R-4: four pieces
• 1704R-5: five pieces

Some bass rods use a slash instead of a hyphen. An Expride model such as 163L-BFS/2 is also a two-piece rod. Treat /2 and -2 as piece-count notation within their respective series.

Piece count does not tell you where the rod separates. A two-piece model may be a conventional center joint, or it may use a grip joint and remain almost full blank length when disassembled.

Zodias model	Joint construction	Pieces	Published packed length
1610M	Grip joint	2	177.4 cm
1610M-2	Put-over ferrule (並継)	2	107 cm

Both rods have a published overall length of 2.08 m, but the -2 model packs much shorter. This is why piece count, joint construction, and packed length must be checked together when choosing a rod for travel or storage.

6. Saltwater rods often begin with S or B

Many Shimano shore and saltwater lure rods use an initial letter instead of the numeric 1 or 2 system.

Initial letter	Reel type
S	Spinning
B	Baitcasting

The remaining digits usually state length in feet and inches, followed by the power class. Read S86ML-S as:

S / 86 / ML / -S

• S: spinning
• 86: 8 feet 6 inches
• ML: medium-light power
• -S: solid tip

This format appears across many eging, seabass, rockfish, and shore-lure families, although the exact suffixes available differ by series.

7. A final -S or -G describes construction in applicable families

-S commonly identifies a solid tip

On applicable saltwater and bass rods, the final -S identifies a solid-tip model. A solid tip is filled through its cross-section, while a tubular tip is hollow. The initial S and final -S serve different purposes in S86ML-S: the first identifies a spinning rod, while the suffix identifies the tip.

The suffix identifies construction, not the exact feel. For example, Sephia SS uses Taftec Infinity on its solid-tip models, while other Shimano families may use a different solid-tip design. Confirm the technology description for the exact model.

-G commonly identifies glass composite

On applicable families, a final -G indicates a glass-composite model. Zodias 166L-G, for example, separates into 1 for baitcasting, 66 for 6 feet 6 inches, L for light power, and -G for glass composite. Because G is not used in exactly the same way across every historic Shimano series, confirm its meaning on the product page before treating it as universal.

8. Four real Shimano model numbers decoded

Zodias 1610M-2

1 / 610 / M / -2

This is a baitcasting rod, 6 feet 10 inches long, with medium power and two pieces.

World Shaula 1652R-3

1 / 65 / 2 / R / -3

This is a baitcasting rod. In the World Shaula system, 65 means 6 feet 6 inches. The rod uses power class 2, regular taper, and three pieces.

Sephia SS S86ML-S

S / 86 / ML / -S

This is an 8-foot-6-inch spinning rod with medium-light power and a solid tip. The SS in the product name is the series grade; the final -S is the tip specification.

Sephia Limited S84L+

S / 84 / L+

This is an 8-foot-4-inch spinning rod with light-plus power. The plus sign places it between the base light class and the next stronger class in the series.

Use the code to narrow the field—not replace the specification table

Read a Shimano rod in this order:

1. Identify the series and grade name.
2. Find the reel-type indicator.
3. Decode the length using that series' convention.
4. Read the power and taper.
5. Check piece count, joint style, and packed length.
6. Confirm tip construction and every exact specification on the product page.

The model number is an efficient filter. It does not replace the published lure range, line range, total length, packed length, or joint construction for the exact model.
