I am new here, but not new to the Sinister family. I have been riding a Sinister 6.3 since they first appeared at Walmart many years ago. I had to deal with a lot of the same issues people have posted about, but once they were addressed it has been a solid ride. It even survived a crash with a tree where I lost the tip of my finger, so it is built pretty well.
Over the past year or so I was thinking of moving to "better" bike, but money is always an issue. Being that this bike has lasted this long, I am starting to look for upgrades people have made. Is there an up to date list of budget friendly upgrades that can be made to the bike out there? I was looking at a DNM rear shock, SR Suntour XCR RL Air Spring MTB Bike Fork, Avid BB7 MTN G2 Front or Rear Rotor, but I have no idea if they will work.

Thanks,
Nubsy

Darn good choices, but check out Aliexpress for the prices. The Epixons are cheap nowadays and its a step above XCRs. We got in a big tussle on this forum for me suggesting Aliexpress, but it really is the cheapest place to buy from. Check out other sites for low prices also. You might also want bigger tires if your using it in rough terrain. 2.35 is my choice but I think the sinister can handle 2.4s but I'm not sure.

Thank you .... I am using it on Long Island, so mostly hard pack, and minimal loose rock and sand when on the MTB trails. I do use it on the road just to get in some miles for cardio once in a while. I just ordered WTB trail Boss 2.25 tires figuring they might be a good fit between road and trail riding. The original tires were Kenda 2.0, but now that I'm doing research I think were not the tires that were supposed to be on it.

I started doing the upgrades this past week, but we had a blizzard, so no chance to try them out yet.
I add 2.25 Trail Boss tires, the DNM rear shock, and a new set of hand grips so far. The next thing on the list are the front forks.

Those 2.25's fill that rear triangle out pretty well. The DNM shocks are a good upgrade. A lot of good reviews and they're priced right too!

Good looking bike. I’m not sure what kind of bottom bracket the bike has nor if you’ve replaced it but I recommend installing a sealed unit before you invest a lot on other upgrades.

Tomcat65 .... They definitely fill it out well. A few people said 2.4's would fit, but I don't see how it could.

orvil .... It's the original BB. I've had to change out the bearing a few time along the way. I was looking at a sealed BB online, and it is definitely on my to do list.

madhatter9631 .... Did you ever get the 120mm forks? I was wondering if there were any issues going up from the 100mm, and what you think of it.

Thank you

A couple things for you to ponder. You say your trails on Long Island are mostly hard pack with some sandy areas and maybe some small chunky rock I imagine. Unless you have some drops, say more than 12”, you’re probably better off with a 100mm fork. Even if you upgrade, a 100mm will be lighter than a 120 unless you spend a lot. When we modify bikes we need to be realistic about how we plan to use the bike so we can spend money where it really matters. Although a better fork will be somewhat lighter than your stock fork, your stock fork may be sufficient for your trails. Also, I’m not positive because I’m currently using my phone, but your front tire, and possibly your rear too, may be mounted backwards. Look on the sidewall for a directional arrow. The knobs usually “point” in the direction of travel. If I’m wrong with this observation then I apologize. Anyway, just trying to help. Believe me I learned A LOT through trial and error haha. We all just want to help and make your cycling more enjoyable. And my personal goal is to make it as tough as you can handle! I love technical trails. My local trails just beyond my back yard will take over an hour for just 4 miles. It will take about 3 hours to ride them all and that’s less than 10 miles currently lol.
