Adding a yamaha g2 golf cart back seat is the quickest way to turn your vintage workhorse into a family-friendly cruiser. If you've got one of these old-school Yamahas sitting in your garage, you already know they're built like tanks. But as great as they are for a round of golf or a quick trip down the driveway, the standard two-seat configuration is pretty limiting. Whether you're trying to haul the grandkids around the neighborhood or you need a way to carry extra gear for a weekend project, that rear seat kit is the missing piece of the puzzle.
The Yamaha G2 is a bit of a legend in the golf cart world. Produced from the late 80s into the early 90s, it was one of the first carts to really nail that balance between a smooth ride and a durable frame. Because they're so well-built, there are still thousands of them humming along today. However, because they're older models, finding the right accessories—like a solid back seat—requires a little bit of know-how. You can't just grab any random kit and expect it to bolt right up without some minor adjustments.
Why the G2 Needs a Rear Seat Upgrade
Most people who own a G2 aren't using them for 18 holes of golf anymore. They've become "neighborhood electric vehicles" or utility carts for large properties. When you're using a cart for chores or social outings, having only two seats feels like a missed opportunity.
A back seat doesn't just add passenger space; it changes how you use the cart. Most modern kits are "flip-flop" or "stationary-to-cargo" designs. This means the seat bottom can fold over to create a flat plastic or metal deck. If you're hauling bags of mulch or a cooler, you flip it down. If the neighbors want a ride to the community pool, you flip it up. It's that versatility that makes the investment worth it.
Choosing the Right Seat Kit
When you start shopping for a yamaha g2 golf cart back seat, you'll notice a lot of options. The most important thing is to ensure the brackets are specifically designed for the G2 or G9 frame. These two models share a lot of DNA, so many kits are labeled for both.
You'll want to look at the material of the seat frame itself. Steel is the standard because it's strong and relatively affordable. However, if you live near the coast or in an area where things rust the moment they step outside, you might want to look for a powder-coated finish or even an aluminum frame if your budget allows. Steel is heavy, which helps with traction, but you have to keep an eye on those weld points over the years to make sure they aren't bubbling.
The cushions are the next big factor. Cheaper kits often use thinner foam that feels like sitting on a piece of plywood after about twenty minutes. If you plan on taking longer rides, look for "marine-grade" vinyl and high-density foam. Marine-grade vinyl is essential because it's UV-resistant. A back seat spends a lot of time baking in the sun, and the last thing you want is for the fabric to crack and peel after one summer.
The Importance of Heavy Duty Springs
Here is the part most people skip, and they usually regret it about a week later. When you add a yamaha g2 golf cart back seat, you aren't just adding the weight of the metal frame and the cushions (which is probably around 50 to 70 pounds). You're adding the weight of two adults.
The stock suspension on a Yamaha G2 was designed to hold two people in the front and two golf bags in the back. If you put two grown men on a rear seat without upgrading your springs, the back of the cart is going to sag like an old mattress. Not only does it look bad, but it makes the steering feel light and floaty because the front tires aren't making solid contact with the ground.
I always recommend picking up a set of heavy-duty rear leaf springs or heavy-duty coil-over shocks at the same time you buy the seat. It makes the ride a bit stiffer when the cart is empty, but it handles the extra load perfectly when you've got a full house.
Installation Tips and Tricks
Installing a back seat on a G2 isn't rocket science, but it's definitely a Saturday afternoon project. You're going to need a basic set of wrenches and sockets—mostly 10mm, 12mm, and 14mm if memory serves.
The first step is usually removing the rear sweater basket and the canopy supports. Since the G2 is an older model, don't be surprised if those bolts are a little stubborn. A bit of penetrating oil like PB Blaster goes a long way here. Give them a soak a few hours before you start, and your knuckles will thank you later.
One thing to watch out for is the rear roof struts. Most back seat kits come with new, longer struts because the original ones won't reach once the seat is in place. You'll want to make sure your kit includes these, or you'll find yourself with a dangling roof and a very frustrated afternoon. When you're bolting the main frame to the cart's chassis, keep the bolts finger-tight until everything is aligned. If you tighten everything down as you go, you'll almost certainly find that the last hole is a half-inch off, and you'll have to loosen it all back up anyway.
Safety Features to Consider
If you're going to have people riding in the back, safety should be on your mind. Golf carts aren't exactly known for their crash ratings, and the people in the back are the most vulnerable.
Most yamaha g2 golf cart back seat kits come with a footrest, which is great, but I'd strongly suggest adding a safety grab bar (sometimes called a "safety bar" or "handrail"). It gives the rear passengers something to hold onto while you're turning corners. It also acts as a bit of a buffer if someone were to accidentally back into something.
Seat belts are another option. Some people find them overkill for a golf cart, but if you have young kids riding in the back, they provide a lot of peace of mind. Most rear seat kits have pre-drilled holes where you can easily bolt on a universal seat belt kit.
Maintaining Your New Seat
Once the seat is on and you're cruising the neighborhood, you'll want to keep it looking fresh. Since the G2 is often an outdoor vehicle, the back seat gets hit with rain, dirt, and sun.
Every few months, check the bolts. Golf carts vibrate a lot, especially if you're driving on gravel or uneven grass. Those vibrations can loosen the hardware over time. A quick once-over with a wrench ensures nobody ends up on the pavement because a support bracket wiggled loose.
For the vinyl, avoid using harsh chemicals. A simple mix of mild soap and water usually does the trick. If you want to use a protectant, make sure it's one designed for marine vinyl that doesn't leave a greasy film. There's nothing worse than sliding right off the seat the first time you take a sharp turn because you over-applied a shiny protectant.
Wrapping It Up
At the end of the day, a yamaha g2 golf cart back seat is probably the single best ROI you can get on an old G2. It doubles your passenger capacity, adds a ton of utility for hauling stuff around, and honestly, it just makes the cart look more complete.
It's one of those projects that feels a bit daunting when you see the box of parts on your driveway, but once it's bolted on and you're out for that first sunset cruise with the whole crew, you'll wonder why you didn't do it years ago. Just remember to grab those heavy-duty springs, take your time with the install, and keep those bolts tight. Your G2 has plenty of life left in it, and a new back seat is the perfect way to enjoy it for another decade.
